NOTES

        This cmdlet uses the Win32_QuickFixEngineering WMI class, which represents small system-wide updates of the operating system. Starting with Windows Vista, this class returns only the updates supplied by Component Based Servicing (CBS). It does not include updates that are supplied by Microsoft Windows Installer (MSI) or the Windows update site. For more information, see the Win32_QuickFixEngineering class topic in the Microsoft .NET Framework SDK at http://go.microsoft.com/fwlink/?LinkID=145071.

        The output of this cmdlet might be different on different operating systems.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Get-HotFix

    Description

cmdlet, Credential, Get

Get-Credential

NAME
    Get-Credential

SYNOPSIS
    Gets a credential object based on a user name and password.

SYNTAX
    Get-Credential [-Credential] <PSCredential> [<CommonParameters>]

DESCRIPTION
    The Get-Credential cmdlet creates a credential object for a specified user name and password. You can use the credential object in security operations.

    The cmdlet prompts the user for a password or user name and password. Users are prompted through a dialog box or at the command line, depending on the system Registry setting.

PARAMETERS
    -Credential <PSCredential>
        Specifies a user name for the credential, such as “User01” or “Domain01\User01”. The parameter name (“Credential”) is optional.

        When you submit the command, you will be prompted for a password.

        If you enter a user name without a domain, Get-Credential inserts a backslash before the name.

        If you omit this parameter, you will be prompted for a user name and a password.

        Required?                    true
        Position?                    1
        Default value                None
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    None
        You cannot pipe input to this cmdlet.

OUTPUTS
    System.Management.Automation.PSCredential
        Get-Credential returns a credential object.

NOTES

        You can use the PSCredential object that Get-Credential creates in cmdlets that request user authentication, such as those with a Credential parameter.

        The Credential parameter is not supported by the providers that are installed with Windows PowerShell. However, you can use the Credential parameter with Get-WmiObject, because it calls the Microsoft .NET Framework directly.

    ————————– EXAMPLE 1 ————————–

    C:\PS>$c = Get-Credential

    Description
    ———–
    This command gets a credential object and saves it in the $c Variable.

    When you enter the command, a dialog box appears requesting a user name and password. When you enter the requested information, the cmdlet creates a PSCredential object representing the credentials of the user and saves it in the $c Variable.

    You can use the object as input to cmdlets that request user authentication, such as those with a Credential parameter. However, the providers that are installed with Windows PowerShell do not support the Credential parameter.

    ————————– EXAMPLE 2 ————————–

    C:\PS>$c = Get-Credential

    C:\PS>Get-WmiObject Win32_DiskDrive -ComputerName Server01 -Credential $c

    Description
    ———–
    These commands use a credential object from Get-Credential to authenticate a user on a remote computer so they can use Windows Management Instrumentation (WMI) to manage the computer.

    The first command gets a credential object and saves it in the $c Variable. The second command uses the credential object in a Get-WmiObject command. This command gets information about the disk drives on the Server01 computer.

    ————————– EXAMPLE 3 ————————–

    C:\PS>C:\PS>Get-WmiObject Win32_BIOS -ComputerName Server01 ‘
    -Credential (Get-Credential Domain01\User01)

    Description
    ———–
    This command shows how to include a Get-Credential command in a Get-WmiObject command.

    This command uses the Get-WmiObject cmdlet to get information about the BIOS on the Server01 computer. It uses the Credential parameter to authenticate the user, Domain01\User01, and a Get-Credential command as the value of the Credential parameter.

    ————————– EXAMPLE 4 ————————–

    C:\PS>$c = Get-Credential -Credential User01

    C:\PS>$c.Username

    \User01

    Description
    ———–
    This example creates a credential that includes a user name without a domain name. It demonstrates that Get-Credential inserts a backslash before the user name.

    The first command gets a credential with the user name User01 and stores it in the $c Variable.

    The second command displays the value of the Username property of the resulting credential object.

    ————————– EXAMPLE 5 ————————–

    C:\PS>$credential = $host.ui.PromptForCredential(“Need credentials”, “Please enter your user name and password.”, “”, “NetBiosUserName”)

    Description
    ———–
    This command uses the PromptForCredential method to prompt the user for their user name and password. The command saves the resulting credentials in the $credential Variable.

    PromptForCredential is an alternative to using Get-Credential. When you use PromptForCredential, you can specify the caption, messages, and user name that appear in the message box.

    ————————– EXAMPLE 6 ————————–

    C:\PS>Set-ItemProperty ‘HKLM:\SOFTWARE\Microsoft\PowerShell\1\ShellIds’ ConsolePrompting $true

    Description
    ———–
    When requiring a user name and password, as a default, a dialog box appears to prompt the user. To be prompted at the command line, modify the Registry by running this command in Windows PowerShell Run as administrator.

    Use the same command with “ConsolePrompting $false” to be prompted with a dialog box.

cmdlet, Content, Get

Get-Content

NAME
    Get-Content

SYNOPSIS
    Gets the content of the item at the specified location.

SYNTAX
    Get-Content [-LiteralPath] <string[]> [-Credential <PSCredential>] [-Exclude <string[]>] [-Filter <string>] [-Force] [-Include <string[]>] [-ReadCount <Int64>] [-TotalCount <Int64>] [-UseTransaction] [<CommonParameters>]

    Get-Content [-Path] <string[]> [-Credential <PSCredential>] [-Exclude <string[]>] [-Filter <string>] [-Force] [-Include <string[]>] [-ReadCount <Int64>] [-TotalCount <Int64>] [-UseTransaction] [<CommonParameters>]

DESCRIPTION
    The Get-Content cmdlet gets the content of the item at the location specified by the path, such as the text in a file. It reads the content one line at a time and returns an object for each line.

PARAMETERS
    -Credential <PSCredential>
        Specifies a user account that has permission to perform this action. The default is the current user.

        Type a user name, such as “User01” or “Domain01\User01”, or enter a PSCredential object, such as one generated by the Get-Credential cmdlet. If you type a user name, you will be prompted for a password.

        This parameter is not supported by any providers that are installed with Windows PowerShell.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Exclude <string[]>
        Omits the specified items. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as “*.txt”. Wildcards are permitted.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Filter <string>
        Specifies a filter in the provider’s format or language. The value of this parameter qualifies the Path parameter. The syntax of the filter, including the use of wildcards, depends on the provider. Filters are more efficient than other parameters, because the provider applies them when retrieving the objects, rather than having Windows PowerShell filter the objects after they are retrieved.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Force [<SwitchParameter>]
        Overrides restrictions that prevent the command from succeeding, just so the changes do not compromise security. For example, Force will override the read-only attribute or create directories to complete a file path, but it will not attempt to change file permissions.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Include <string[]>
        Retrieves only the specified items. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as “*.txt”. Wildcards are permitted.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -LiteralPath <string[]>
        Specifies the path to an item. Unlike Path, the value of LiteralPath is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell Windows PowerShell not to interpret any characters as escape sequences.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Path <string[]>
        Specifies the path to an item. Get-Content retrieves the content of the item. Wildcards are permitted. The parameter name (“Path” or “FilePath”) is optional.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -ReadCount <Int64>
        Specifies how many lines of content are sent through the pipeline at a time. The default value is 1. A value of 0 (zero) sends all of the content at one time.

        This parameter does not change the content displayed, but it does affect the time it takes to display the content. As the value of ReadCount increases, the time it takes to return the first line increases, but the total time for the operation decreases. This can make a perceptible difference in very large items.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -TotalCount <Int64>
        Specifies how many lines of content are retrieved. The default is -1 (all lines).

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -UseTransaction [<SwitchParameter>]
        Includes the command in the active transaction. This parameter is valid only when a transaction is in progress. For more information, see about_transactions.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    None
        You cannot pipe input to Get-Content.

OUTPUTS
    Object
        Get-Content returns objects that represent the content that it gets. The object type depends on the content type.

NOTES

        You can also refer to Get-Content by its built-in Aliases, “cat”, “type” and “gc”. For more information, see about_aliases.

        The Get-Content cmdlet is designed to work with the data exposed by any provider. To list the providers available in your session, type “Get-PSProvider“. For more information, see about_providers.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Get-Content -Path C:\Chapters\chapter1.txt

    Description
    ———–
    This command displays the content of the Chapter1.txt file on the console. It uses the Path parameter to specify the name of the item. Get-Content actually passes the content down the pipeline, but because there are no other pipeline elements, the content is formatted and displayed on the console.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Get-Content c:\Logs\Log060912.txt -TotalCount 50 | Set-Content sample.txt

    Description
    ———–
    This command gets the first 50 lines of the Log060912.txt file and stores them in the sample.txt file. The command uses the Get-Content cmdlet to get the text in the file. (The name of Path parameter, which is optional, is omitted.) The TotalCount parameter limits the retrieval to the first 50 lines. The pipeline operator (|) sends the result to Set-Content, which places it in the sample.txt file.

    ————————– EXAMPLE 3 ————————–

    C:\PS>(Get-Content cmdlets.txt -TotalCount 5)[-1]

    Description
    ———–
    This command gets the fifth line of the Cmdlets.txt text file. It uses the TotalCount parameter to get the first five lines and then uses array notation to get the last line (indicated by “-1”) of the resulting set.

Enter-PSSession

NAME
    Enter-PSSession

SYNOPSIS
    Starts an interactive session with a remote computer.

SYNTAX
    Enter-PSSession [-ComputerName] <string> [-ApplicationName <string>] [-Authentication {Default | Basic | Negotiate | NegotiateWithImplicitCredential | Credssp | Digest | Kerberos}] [-CertificateThumbprint <string>] [-ConfigurationName <string>] [-Credential <PSCredential>] [-Port <int>] [-SessionOption <PSSessionOption>] [-UseSSL] [<CommonParameters>]

    Enter-PSSession [[-Id] <int>] [<CommonParameters>]

    Enter-PSSession [-InstanceId <Guid>] [<CommonParameters>]

    Enter-PSSession [-Name <string>] [<CommonParameters>]

    Enter-PSSession [[-Session] <PSSession>] [<CommonParameters>]

    Enter-PSSession [[-ConnectionURI] <Uri>] [-AllowRedirection] [-Authentication {Default | Basic | Negotiate | NegotiateWithImplicitCredential | Credssp | Digest | Kerberos}] [-CertificateThumbprint <string>] [-ConfigurationName <string>] [-Credential <PSCredential>] [-SessionOption <PSSessionOption>] [<CommonParameters>]

DESCRIPTION
    The Enter-PSSession cmdlet starts an interactive session with a single remote computer. During the session, the commands that you type run on the remote computer, just as though you were typing directly on the remote computer. You can have only one interactive session at a time.

    Typically, you use the ComputerName parameter to specify the name of the remote computer. However, you can also use a session that you create by using New-PSSession for the interactive session.

    To end the interactive session and disconnect from the remote computer, use the Exit-PSSession cmdlet, or type “exit”.

PARAMETERS
    -AllowRedirection [<SwitchParameter>]
        Allows redirection of this connection to an alternate Uniform Resource Identifier (URI).

        When you use the ConnectionURI parameter, the remote destination can return an instruction to redirect to a different URI. By default, Windows PowerShell does not redirect connections, but you can use this parameter to allow it to redirect the connection.

        Allows redirection of this connection to an alternate URI.

        When you use the ConnectionURI parameter, the remote destination can return an instruction to redirect to a different URI. By default, Windows PowerShell does not redirect connections, but you can use the AllowRedirection parameter to allow it to redirect the connection.

        You can also limit the number of times that the connection is redirected by setting the MaximumConnectionRedirectionCount property of the $PSSessionOption preference Variable, or the MaximumConnectionRedirectionCount property of the value of the SessionOption parameter. The default value is 5. For more information, see the description of the SessionOption parameter, and see New-PSSessionOption.

        Required?                    false
        Position?                    named
        Default value                False
        Accept pipeline input?     false
        Accept wildcard characters? false

    -ApplicationName <string>
        Specifies the application name segment of the connection URI. Use this parameter to specify the application name when you are not using the ConnectionURI parameter in the command.

        The default value is the value of the $PSSessionApplicationName preference Variable on the local computer. If this preference Variable is not defined, the default value is WSMan. This value is appropriate for most uses. For more information, see about_preference_variables.

        The WinRM service uses the application name to select a listener to service the connection request. The value of this parameter should match the value of the URLPrefix property of a listener on the remote computer.

        Required?                    false
        Position?                    named
        Default value                WSMan
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Authentication <AuthenticationMechanism>
        Specifies the mechanism that is used to authenticate the user’s credentials. Valid values are “Default”, “Basic”, “Credssp”, “Digest”, “Kerberos”, “Negotiate”, and “NegotiateWithImplicitCredential”. The default value is “Default”.

        CredSSP authentication is available only in Windows Vista, Windows Server 2008, and later versions of Windows.

        For information about the values of this parameter, see the description of the System.Management.Automation.Runspaces.AuthenticationMechanism enumeration in the MSDN (Microsoft Developer Network) library at http://go.microsoft.com/fwlink/?LinkId=144382.

        Caution: Credential Security Service Provider (CredSSP) authentication, in which the user’s credentials are passed to a remote computer to be authenticated, is designed for commands that require authentication on more than one resource, such as accessing a remote network share. This mechanism increases the security risk of the remote operation. If the remote computer is compromised, the credentials that are passed to it can be used to control the network session.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -CertificateThumbprint <string>
        Specifies the digital public key Certificate (X509) of a user account that has permission to perform this action. Enter the Certificate thumbprint of the Certificate.

        Certificates are used in client Certificate-based authentication. They can be mapped only to local user accounts; they do not work with domain accounts.

        To get a Certificate thumbprint, use the Get-Item or Get-ChildItem command in the Windows PowerShell Cert: drive.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -ComputerName <string>
        Starts an interactive session with the specified remote computer. Enter only one computer name. The default is the local computer.

        Type the NetBIOS name, an IP address, or a fully qualified domain name of one or more remote computers. You can also pipe a computer name to Enter-PSSession.

        To use an IP address in the value of the ComputerName parameter, the command must include the Credential parameter. Also, the computer must be configured for HTTPS transport or the IP address of the remote computer must be included in the WinRM TrustedHosts list on the local computer. For instructions for adding a computer name to the TrustedHosts list, see “How to Add a Computer to the Trusted Host List” in about_remote_TroubleShooting.

        Note: In Windows Vista and later versions of Windows, to include the local computer in the value of the ComputerName parameter, you must start Windows PowerShell with the “Run as administrator” option.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByValue, ByPropertyName)
        Accept wildcard characters? false

    -ConfigurationName <string>
        Specifies the session configuration that is used for the interactive session.

        Enter a configuration name or the fully qualified resource URI for a session configuration. If you specify only the configuration name, the following schema URI is prepended: http://schemas.microsoft.com/powershell.

        The session configuration for a session is located on the remote computer. If the specified session configuration does not exist on the remote computer, the command fails.

        The default value is the value of the $PSSessionConfigurationName preference Variable on the local computer. If this preference Variable is not set, the default is Microsoft.PowerShell. For more information, see about_preference_variables.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -ConnectionURI <Uri>
        Specifies a Uniform Resource Identifier (URI) that defines the connection endpoint for the interactive session. The URI must be fully qualified.

        The format of this string is as follows:
            <Transport>://<ComputerName>:<Port>/<ApplicationName>

        The default value is as follows:
            http://localhost:80/WSMAN

        Valid values for the Transport segment of the URI are HTTP and HTTPS. If you do not specify a ConnectionURI, you can use the UseSSL, ComputerName, Port, and ApplicationName parameters to specify the URI values.

        If the destination computer redirects the connection to a different URI, Windows PowerShell prevents the redirection unless you use the AllowRedirection parameter in the command.

        Required?                    false
        Position?                    2
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Credential <PSCredential>
        Specifies a user account that has permission to perform this action. The default is the current user.

        Type a user name, such as “User01”, “Domain01\User01”, or “User@Domain.com”, or enter a PSCredential object, such as one returned by the Get-Credential cmdlet.

        When you type a user name, you will be prompted for a password.

        Required?                    false
        Position?                    named
        Default value                Current user
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Id <int>
        Specifies the ID of an existing session. Enter-PSSession uses the specified session for the interactive session.

        To find the ID of a session, use the Get-PSSession cmdlet.

        Required?                    false
        Position?                    1
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -InstanceId <Guid>
        Specifies the instance ID of an existing session. Enter-PSSession uses the specified session for the interactive session.

        The instance ID is a GUID. To find the instance ID of a session, use the Get-PSSession cmdlet. You can also use the Session, Name, or ID parameters to specify an existing session. Or, you can use the ComputerName parameter to start a temporary session.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Name <string>
        Specifies the friendly name of an existing session. Enter-PSSession uses the specified session for the interactive session.

        If the name that you specify matches more than one session, the command fails. You can also use the Session, InstanceID, or ID parameters to specify an existing session. Or, you can use the ComputerName parameter to start a temporary session.

        To establish a friendly name for a session, use the Name parameter of the New-PSSession cmdlet.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Port <int>
        Specifies the network port on the remote computer used for this command. The default is port 80 (the HTTP port).

        Before using an alternate port, you must configure the WinRM listener on the remote computer to listen at that port. Use the following commands to configure the listener:

        1. winrm delete winrm/config/listener?Address=*+Transport=HTTP
        2. winrm create winrm/config/listener?Address=*+Transport=HTTP @{Port=”<port-number>”}

        Do not use the Port parameter unless you must. The port setting in the command applies to all computers or sessions on which the command runs. An alternate port setting might prevent the command from running on all computers.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Session <PSSession>
        Specifies a Windows PowerShell session (PSSession) to use for the interactive session. This parameter takes a session object. You can also use the Name, InstanceID, or ID parameters to specify a PSSession.

        Enter a Variable that contains a session object or a command that creates or gets a session object, such as a New-PSSession or Get-PSSession command. You can also pipe a session object to Enter-PSSession. You can submit only one PSSession with this parameter. If you enter a Variable that contains more than one PSSession, the command fails.

        When you use Exit-PSSession or the EXIT keyword, the interactive session ends, but the PSSession that you created remains open and available for use.

        Required?                    false
        Position?                    1
        Default value
        Accept pipeline input?     true (ByValue, ByPropertyName)
        Accept wildcard characters? true

    -SessionOption <PSSessionOption>
        Sets advanced options for the session. Enter a SessionOption object that you create by using the New-PSSessionOption cmdlet.

        The default values for the options are determined by the value of the $PSSessionOption preference Variable, if it is set. Otherwise, the session uses the system defaults.

        For a description of the session options, including the default values, see New-PSSessionOption. For information about the $PSSessionOption preference Variable, see about_preference_variables.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -UseSSL [<SwitchParameter>]
        Uses the Secure Sockets Layer (SSL) protocol to establish a connection to the remote computer. By default, SSL is not used.

        WS-Management encrypts all Windows PowerShell content transmitted over the network. UseSSL is an additional protection that sends the data across an HTTPS connection instead of an HTTP connection.

        If you use this parameter, but SSL is not available on the port used for the command, the command fails.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    System.String or System.Management.Automation.Runspaces.PSSession
        You can pipe a computer name (a string) or a session object to Enter-PSSession.

OUTPUTS
    None
        The cmdlet does not return any output.

NOTES

        — To connect to a remote computer, you must be a member of the Administrators group on the remote computer.

        — In Windows Vista and later versions of Windows, to start an interactive session on the local computer, you must start Windows PowerShell with the “Run as administrator” option.

        — When you use Enter-PSSession, your user profile on the remote computer is used for the interactive session. The commands in the remote user profile, including commands to add Windows PowerShell snap-ins and to change the command prompt, run before the remote prompt is displayed.

        — Enter-PSSession uses the UI culture setting on the local computer for the interactive session. To find the local UI culture, use the $UICulture automatic Variable.

        — Enter-PSSession requires the Get-Command, Out-Default, and Exit-PSSession cmdlets. If these cmdlets are not included in the session configuration on the remote computer, the Enter-PSSession commands fails.

        — Unlike Invoke-Command, which parses and interprets the commands before sending them to the remote computer, Enter-PSSession sends the commands directly to the remote computer without interpretation.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Enter-PSSession

    LocalHost\PS>

    Description
    ———–
    This command starts an interactive session on the local computer. The command prompt changes to indicate that you are now running commands in a different session.

    The commands that you enter run in the new session, and the results are returned to the default session as text.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Enter-PSSession -computer Server01

    Server01\PS> Get-Process powershell > C:\ps-test\process.txt

    Server01\PS> Exit-PSSession
    C:\PS>

    C:\PS> dir C:\ps-test\process.txt
    Get-ChildItem : Cannot find path ‘C:\ps-test\process.txt’ because it does not exist.
    At line:1 char:4
    + dir <<<< c:\ps-test\process.txt

    Description
    ———–
    This command shows how to work in an interactive session with a remote computer.

    The first command uses the Enter-PSSession cmdlet to start an interactive session with Server01, a remote computer. When the session starts, the command prompt changes to include the computer name.

    The second command gets the PowerShell process and redirects the output to the Process.txt file. The command is submitted to the remote computer, and the file is saved on the remote computer.

    The third command uses the Exit keyword to end the interactive session and close the connection.

    The fourth command confirms that the Process.txt file is on the remote computer. A Get-ChildItem (“dir”) command on the local computer cannot find the file.

    ————————– EXAMPLE 3 ————————–

    C:\PS>$s = New-PSSession -ComputerName Server01

    C:\PS> Enter-PSSession -session $s

    Server01\PS>

    Description
    ———–
    These commands use the Session parameter of Enter-PSSession to run the interactive session in an existing Windows PowerShell session (PSSession).

    ————————– EXAMPLE 4 ————————–

    C:\PS>Enter-PSSession -ComputerName Server01 -Port 90 -Credential domain01\user01

    Server01\PS>

    Description
    ———–
    This command starts an interactive session with the Server01 computer. It uses the Port parameter to specify the port and the Credential parameter to specify the account of a user with permission to connect to the remote computer.

    ————————– EXAMPLE 5 ————————–

    C:\PS>Enter-PSSession -ComputerName Server01

    Server01:\PS> Exit-PSSession

    C:\PS>

    Description
    ———–
    This example shows how to start and stop an interactive session. The first command uses the Enter-PSSession cmdlet to start an interactive session with the Server01 computer.

    The second command uses the Exit-PSSession cmdlet to end the session. You can also use the Exit keyword to end the interactive session. Exit-PSSession and Exit have the same effect.

cmdlet, Connect, WSMan

Connect-WSMan

NAME
    Connect-WSMan

SYNOPSIS
    Connects to the WinRM service on a remote computer.

SYNTAX
    Connect-WSMan [-ApplicationName <string>] [-ComputerName <string>] [-Port <int>] [-UseSSL] [-Authentication <Authentication>] [-ComputerName <string>] [-Credential <PSCredential>] [-Port <int>] [-SessionOption <hashtable>] [<CommonParameters>]

    Connect-WSMan [-ConnectionURI <Uri>] [-Authentication <Authentication>] [-ComputerName <string>] [-Credential <PSCredential>] [-Port <int>] [-SessionOption <hashtable>] [<CommonParameters>]

DESCRIPTION
    The Connect-WSMan cmdlet connects to the WinRM service on a remote computer, and it establishes a persistent connection to the remote computer. You can use this cmdlet within the context of the WS-Management provider to connect to the WinRM service on a remote computer. However, you can also use this cmdlet to connect to the WinRM service on a remote computer before you change to the WS-Management provider. The remote computer will appear in the root directory of the WS-Management provider.

    For more information about how to disconnect from the WinRM service on a remote computer, see Disconnect-WSMan.

PARAMETERS
    -ApplicationName <string>
        Specifies the application name in the connection. The default value of the ApplicationName parameter is “WSMAN”. The complete identifier for the remote endpoint is in the following format:
             <transport>://<server>:<port>/<ApplicationName>
        For example:
             http://server01:8080/WSMAN

        Internet Information Services (IIS), which hosts the session, forwards requests with this endpoint to the specified application. This default setting of “WSMAN” is appropriate for most uses. This parameter is designed to be used when numerous computers establish remote connections to one computer that is running Windows PowerShell. In this case, IIS hosts Web Services for Management (WS-Management) for efficiency.

        Required?                    false
        Position?                    named
        Default value                WSMan
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Authentication <Authentication>
        Specifies the authentication mechanism to be used at the server. Possible values are:

        – Basic: Basic is a scheme in which the user name and password are sent in clear text to the server or proxy.
        – Default : Use the authentication method implemented by the WS-Management protocol. This is the default.
        – Digest: Digest is a challenge-response scheme that uses a server-specified data string for the challenge.
        – Kerberos: The client computer and the server mutually authenticate by using Kerberos Certificates.
        – Negotiate: Negotiate is a challenge-response scheme that negotiates with the server or proxy to determine the scheme to use for authentication. For example, this parameter value allows negotiation to determine whether the Kerberos protocol or NTLM is used.
        – CredSSP: Use Credential Security Service Provider (CredSSP) authentication, which allows the user to delegate credentials. This option is designed for commands that run on one remote computer but collect data from or run additional commands on other remote computers.

        Caution: CredSSP delegates the user’s credentials from the local computer to a remote computer. This practice increases the security risk of the remote operation. If the remote computer is compromised, when credentials are passed to it, the credentials can be used to control the network session.

        Required?                    false
        Position?                    named
        Default value                Default
        Accept pipeline input?     false
        Accept wildcard characters? false

    -ComputerName <string>
        Specifies the computer against which you want to run the management operation. The value can be a fully qualified domain name, a NetBIOS name, or an IP address. Use the local computer name, use localhost, or use a dot (.) to specify the local computer. The local computer is the default. When the remote computer is in a different domain from the user, you must use a fully qualified domain name must be used. You can pipe a value for this parameter to the cmdlet.

        Required?                    false
        Position?                    named
        Default value                localhost
        Accept pipeline input?     false
        Accept wildcard characters? false

    -ConnectionURI <Uri>
        Specifies the connection endpoint. The format of this string is:

             <Transport>://<Server>:<Port>/<ApplicationName>.

        The following string is a properly formatted value for this parameter:

             http://Server01:8080/WSMAN. The URI must be fully qualified .

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Credential <PSCredential>
        Specifies a user account that has permission to perform this action. The default is the current user. Type a user name, such as “User01”, “Domain01\User01”, or “User@Domain.com”. Or, enter a PSCredential object, such as one returned by the Get-Credential cmdlet. When you type a user name, you will be prompted for a password.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -OptionSet <hashtable>
        Passes a set of switches to the service to modify or refine the nature of the request. These are similar to switches used in command-line shells in that they are service specific. Any number of options can be specified.

        The following example demonstrates the syntax that passes the values 1, 2, and 3 for the a, b, and c parameters:

             -OptionSet @{a=1;b=2;c=3}

        Required?
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Port <int>
        Specifies the port to use when the client connects to the WinRM service. When the transport is HTTP, the default port is 80. When the transport is HTTPS, the default port is 443. When you use HTTPS as the transport, the value of the ComputerName parameter must match the server’s Certificate common name (CN). However, if the SkipCNCheck parameter is specified as part of the SessionOption parameter, then the Certificate common name of the server does not have to match the host name of the server. The SkipCNCheck parameter should be used only for trusted computers.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -SessionOption <hashtable>
        Defines a set of extended options for the WS-Management session. Enter a SessionOption object that you create by using the New-WSManSessionOption cmdlet. For more information about the options that are available, see New-WSManSessionOption.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -UseSSL [<SwitchParameter>]
        Specifies that the Secure Sockets Layer (SSL) protocol should be used to establish a connection to the remote computer. By default, SSL is not used.

        WS-Management encrypts all the Windows PowerShell content that is transmitted over the network. The UseSSL parameter lets you specify the additional protection of HTTPS instead of HTTP. If SSL is not available on the port that is used for the connection and you specify this parameter, the command fails.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

        This cmdlet does not generate any output.

NOTES

        You can run management commands or query management data on a remote computer without creating a WS-Management session. You can do this by using the ComputerName parameters of Invoke-WSManAction and Get-WSManInstance. When you use the ComputerName parameter, Windows PowerShell creates a temporary connection that is used for the single command. After the command runs, the connection is closed.

    This command creates a connection to the remote server01 computer.

    The Connect-WSMan cmdlet is generally used within the context of the WS-Management provider to connect to a remote computer, in this case the server01 computer. However, you can use the cmdlet to establish connections to remote computers before you change to the WS-Management provider. Those connections will appear in the ComputerName list.

    Description
    ———–
    This command creates a connection to the remote system server01 using the Administrator account credentials.

    The first command uses the Get-Credential cmdlet to get the Administrator credentials and then stores them in the $cred Variable. The Get-Credential cmdlet prompts the user for a password of username and password. Users are prompted throught a dialog box
    or at the command line, depending on system Registry settings.

    The second command uses the Credential parameter to pass the credentials stored in $cred to Connect-WSMan. Connect-WSMan then connects to the remote system server01 using the Administrator credentials.

    The Connect-WSMan cmdlet is generally used within the context of the WS-Management provider to connect to a remote computer, in this case server01. However, the cmdlet can be used establish connections to remote computers before changing to the WS-Management provider and those connections will show up in the ComputerName list.

    Description
    ———–
    This command creates a connection to the remote server01 computer over port 80.

    The Connect-WSMan cmdlet is generally used within the context of the WS-Management provider to connect to a remote computer, in this case the server01 computer. However, you can use the cmdlet to establish connections to remote computers before you change to the WS-Management provider. Those connections will appear in the ComputerName list.

    Description
    ———–
    This command creates a connection to the remote server01 computer by using the connection options that are defined in the New-WSManSessionOption command.

    The first command uses the New-WSManSessionOption cmdlet to store a set of connection setting options in the $a Variable. In this case, the session options set a connection time out of 30 seconds (30,000 milliseconds).

    The second command uses the SessionOption parameter to pass the credentials that are stored in the $a Variable to Connect-WSMan. Then, Connect-WSMan connects to the remote server01 computer by using the specified session options.

    The Connect-WSMan cmdlet is generally used within the context of the WS-Management provider to connect to a remote computer, in this case the server01 computer. However, you can use the cmdlet to establish connections to remote computers before you change to the WS-Management provider. Those connections will appear in the ComputerName list.

Clear, cmdlet, Item

Clear-Item

NAME
    Clear-Item

SYNOPSIS
    Deletes the contents of an item, but does not delete the item.

SYNTAX
    Clear-Item [-LiteralPath] <string[]> [-Credential <PSCredential>] [-Exclude <string[]>] [-Filter <string>] [-Force] [-Include <string[]>] [-Confirm] [-WhatIf] [-UseTransaction] [<CommonParameters>]

    Clear-Item [-Path] <string[]> [-Credential <PSCredential>] [-Exclude <string[]>] [-Filter <string>] [-Force] [-Include <string[]>] [-Confirm] [-WhatIf] [-UseTransaction] [<CommonParameters>]

DESCRIPTION
    The Clear-Item cmdlet deletes the value of an item, but it does not delete the item. For example, Clear-Item can delete the value of a Variable, but it does not delete the Variable. The value that used to represent a cleared item is defined by each Windows PowerShell provider. Clear-Item is similar to Clear-Content, but it works on Aliases and Variables, instead of files.

PARAMETERS
    -Credential <PSCredential>
        Specifies a user account that has permission to perform this action. The default is the current user.

        Type a user name, such as “User01” or “Domain01\User01”, or enter a PSCredential object, such as one generated by the Get-Credential cmdlet. If you type a user name, you will be prompted for a password.

        This parameter is not supported by any providers installed with Windows PowerShell.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Exclude <string[]>
        Omits the specified items. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as “*.txt”. Wildcards are permitted.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Filter <string>
        Specifies a filter in the provider’s format or language. The value of this parameter qualifies the Path parameter. The syntax of the filter, including the use of wildcards, depends on the provider. Filters are more efficient than other parameters, because the provider applies them when retrieving the objects, rather than having Windows PowerShell filter the objects after they are retrieved.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Force [<SwitchParameter>]
        Allows the cmdlet to clear items that cannot otherwise be changed, such as read- only Aliases. The cmdlet cannot clear constants. Implementation varies from provider to provider. For more information, see about_providers. Even using the Force parameter, the cmdlet cannot override security restrictions.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -Include <string[]>
        Clears only the specified items. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as “*.txt”. Wildcards are permitted.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -LiteralPath <string[]>
        Specifies the path to the items being cleared. Unlike Path, the value of LiteralPath is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell Windows PowerShell not to interpret any characters as escape sequences.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByPropertyName)
        Accept wildcard characters? false

    -Path <string[]>
        Specifies the path to the items being cleared. Wildcards are permitted. This parameter is required, but the parameter name (“Path”) is optional.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (ByValue, ByPropertyName)
        Accept wildcard characters? false

    -Confirm [<SwitchParameter>]
        Prompts you for confirmation before executing the command.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -WhatIf [<SwitchParameter>]
        Describes what would happen if you executed the command without actually executing the command.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    -UseTransaction [<SwitchParameter>]
        Includes the command in the active transaction. This parameter is valid only when a transaction is in progress. For more information, see about_transactions.

        Required?                    false
        Position?                    named
        Default value
        Accept pipeline input?     false
        Accept wildcard characters? false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    System.String
        You can pipe a path string to Clear-Item.

OUTPUTS
    None
        This cmdlet does not return any objects.

NOTES

        The Clear-Item cmdlet is supported only by several Windows PowerShell providers, including the Alias, Environment, Function, Registry, and Variable providers. As such, you can use Clear-Item to delete the content of items in the provider namespaces.

        You cannot use Clear-Item to delete the contents of a file, because the Windows PowerShell FileSystem provider does not support this cmdlet. To clear files, use Clear-Content.

        You can also refer to Clear-Item by its built-in Alias, “cli”. For more information, type “Get-Help about_aliases“.

        The Clear-Item cmdlet is designed to work with the data exposed by any provider. To list the providers available in your session, type “Get-PSProvider“. For more information, see about_providers.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Clear-Item Variable:TestVar1

    Description
    ———–
    This command deletes the value of the Variable, Testvar1. The Variable remains and is valid, but its value is set to null.

    The Variable name is prefixed with “Variable:” to indicate the Windows PowerShell Variable provider. To get the same result, you can switch to the Windows PowerShell Variable provider namespace first and then perform the Clear-Item command.

        PS C:> Set-Location Variable:
        PS Variable:\> Clear-Item Testvar1

    ————————– EXAMPLE 2 ————————–

    C:\PS>Clear-Item Alias:log* -Include *1* -Exclude *3* -WhatIf

    What if: Performing operation “Clear Item” on Target “Item: log1”.

    Description
    ———–
    This command asks Windows PowerShell what would happen if you executed the command, “Clear-Item Alias:log* -Include *1* -Exclude *3″. In response, Windows PowerShell explains that it would delete the value of the log1 Alias.

    This command would not have any effect on the log, log2, or log13 Aliases. Because the Alias provider does not permit an Alias without a value, when you clear an Alias, you also delete the Alias.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Clear-Item Registry::HKLM\Software\MyCompany\MyKey -Confirm

    Description
    ———–
    This command deletes all Registry entries in the MyKey subkey, but only after prompting you to confirm your intent. It does not delete the MyKey subkey or affect any other Registry keys or entries. You can use the Include and Exclude parameters to identify particular Registry keys, but you cannot use them to identify Registry entries. To delete particular Registry entries, use Remove-ItemProperty. To delete the value of a Registry entry, use Clear-ItemProperty.

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer and OutVariable. For more information, type,
        “Get-Help about_CommonParameters“.

INPUTS
    None
        You cannot pipe objects to Clear-Content.

OUTPUTS
    None
        This cmdlet does not return any objects.

NOTES

        You can also refer to Clear-Content by its built-in Alias, “clc”. For more information, see about_aliases.

        If you omit the -Path parameter name, the value of Path must be the first parameter in the command. For example, “Clear-Content c:\mydir\*.txt”. If you include the parameter name, you can list the parameters in any order.

        You can use Clear-Content with the Windows PowerShell File System provider and with other providers that manipulate content. To clear items that are not considered to be content, such as items managed by the Windows PowerShell Certificate or Registry providers, use Clear-Item.

        The Clear-Content cmdlet is designed to work with the data exposed by any provider. To list the providers available in your session, type “Get-PSProvider“. For more information, see about_providers.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Clear-Content ..\SmpUsers\*\init.txt

    Description
    ———–
    This command deletes all of the content from the “init.txt” files in all subdirectories of the SmpUsers directory. The files are not deleted, but they are empty.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Clear-Content -Path * -Filter *.log -Force

    Description
    ———–
    This command deletes the contents of all files in the current directory with the “.log” file name extension, including files with the read-only attribute. The asterisk (*) in the path represents all items in the current directory. The Force parameter makes the command effective on read-only files. Using a filter to restrict the command to files with the “.log” file name extension instead of specifying “*.log” in the path makes the operation faster.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Clear-Content c:\Temp\* -Include Smp* -Exclude *2* -WhatIf

    Description
    ———–
    This command requests a prediction of what would happen if you submitted the command: “Clear-Content c:\temp\* -Include smp* -Exclude *2*”. The result lists the files that would be cleared; in this case, files in the Temp directory whose names begin with “Smp”, unless the file names include a “2”. To execute the command, run it again without the Whatif parameter.
