Set-Service

NAME
    Set-Service

SYNOPSIS
    Starts, stops, and suspends a service, and changes its properties.

SYNTAX
    Set-Service [-Name] <string> [-Description <string>] [-DisplayName <string>] [-PassThru] [-StartupType {Automatic | Manual | Disabled}] [-Status <string>] [-ComputerName <string[]>] [-Confirm] [-WhatIf] [<CommonParameters>]

    Set-Service [-Description <string>] [-DisplayName <string>] [-InputObject <ServiceController>] [-PassThru] [-StartupType {Automatic | Manual | Disabled}] [-Status <string>] [-ComputerName <string[]>] [-Confirm] [-WhatIf] [<CommonParameters>]

DESCRIPTION
    The Set-Service cmdlet changes the properties of a local or remote service, including the status, description, display name, and start mode. You can use this cmdlet to start, stop, or suspend (pause) a service. To identify the service, enter its service name or submit a service object, or pipe a service name or service object to Set-Service.

PARAMETERS
    -ComputerName <string[]>
        Specifies one or more computers. The default is the local computer.

        Type the NetBIOS name, an IP address, or a fully qualified domain name of a remote computer. To specify the local computer, type the computer name, a dot (.), or “localhost”.

        This parameter does not rely on Windows PowerShell remoting. You can use the ComputerName parameter of Set-Service even if your computer is not configured to run remote commands.

    <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.ServiceProcess.ServiceController, System.String
        You can pipe a service object or a string that contains a service name to Set-Service.

OUTPUTS
    None
        This cmdlet does not return any objects.

NOTES

        To use Set-Service on Windows Vista and later versions of Windows, start Windows PowerShell with the “Run as administrator” option.

        Set-Service can control services only when the current user has permission to do so. If a command does not work correctly, you might not have the required permissions.

        To find the service names and display names of the services on your system, type “Get-Service“. The service names appear in the Name column and the display names appear in the DisplayName column.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Set-Service -Name lanmanworkstation -DisplayName “LanMan Workstation”

    Description
    ———–
    This command changes the display name of the lanmanworkstation service to “LanMan Workstation”. (The default is “Workstation”.)

    ————————– EXAMPLE 2 ————————–

    C:\PS>Get-WmiObject win32_service -filter “name = ‘SysmonLog'”

    ExitCode : 0
    Name     : SysmonLog
    ProcessId : 0
    StartMode : Manual
    State     : Stopped
    Status    : OK

    C:\PS> Set-Service sysmonlog -StartupType automatic

    C:\PS> Get-WmiObject win32_service -filter “name = ‘SysmonLog'”

    ExitCode : 0
    Name     : SysmonLog
    ProcessId : 0
    StartMode : Auto
    State     : Stopped
    Status    : OK

    C:\PS> Get-WmiObject win32_service | Format-Table Name, StartMode -auto

    Name                                 StartMode
    —-                                 ———
    AdtAgent                             Auto
    Alerter                             Disabled
    ALG                                 Manual
    AppMgmt                             Manual
    …

    Description
    ———–
    These commands get the startup type of the Performance Logs and Alerts (SysmonLog) service, set the start mode to automatic, and then display the result of the change.

    These commands use the Get-WmiObject cmdlet to get the Win32_Service object for the service, because the ServiceController object that Get-Service returns does not include the start mode.

    The first command uses the Get-WmiObject cmdlet to get the Windows Management Instrumentation (WMI) object that represents the SysmonLog service. The default output of this command displays the start mode of the service.

    The second command uses Set-Service to change the start mode to automatic. Then, the first command is repeated to display the change.

    The final command displays the start mode of all services on the computer.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Set-Service -Name Schedule -ComputerName S1 -Description “Configures and schedules tasks.”

    C:\PS> Get-WmiObject win32_service -ComputerName s1 | Where-Object {$_.Name -eq “Schedule”} | Format-List Name, Description

    Description
    ———–
    These commands change the description of the Task Scheduler service on the S1 remote computer and then display the result.

    These commands use the Get-WmiObject cmdlet to get the Win32_Service object for the service, because the ServiceController object that Get-Service returns does not include the service description.

    The first command uses a Set-Service command to change the description. It identifies the service by using the service name of the service, “Schedule”.

    The second command uses the Get-WmiObject cmdlet to get an instance of the WMI Win32_Service that represents the Task Scheduler service. The first element in the command gets all instances of the Win32_service class.

    The pipeline operator (|) passes the result to the Where-Object cmdlet, which selects instances with a value of “Schedule” in the Name property.

    Another pipeline operator sends the result to the Format-List cmdlet, which formats the output as a list with only the Name and Description properties.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Set-Service winrm -Status Running -PassThru -ComputerName Server02

    Description
    ———–
    This command starts the WinRM service on the Server02 computer. The command uses the Status parameter to specify the desired status (“running”) and the PassThru parameter to direct Set-Service to return an object that represents the WinRM service.

    ————————– EXAMPLE 5 ————————–

    C:\PS>Get-Service schedule -ComputerName S1, S2 | Set-Service -Status paused

    Description
    ———–
    This command suspends the Schedule service on the S1 and S2 remote computers. It uses the Get-Service cmdlet to get the service. A pipeline operator (|) sends the service to the Set-Service cmdlet, which changes its status to “Paused”.

    ————————– EXAMPLE 6 ————————–

    C:\PS>$s = Get-Service schedule

    C:\PS> Set-Service -inputobject $s -Status stopped

    Description
    ———–
    These commands stop the Schedule service on the local computer.

    The first command uses the Get-Service cmdlet to get the Schedule service. The command saves the service in the $s Variable.

    The second command uses the Set-Service cmdlet to change the status of the Schedule service to “Stopped”. It uses the InputObject parameter to submit the service stored in the $s Variable, and it uses the Status parameter to specify the desired status.

        “Get-Help about_CommonParameters“.

INPUTS
    System.String
        You can pipe a string that contains a name to Set-TraceSource.

OUTPUTS
    None or System.Management.Automation.PSTraceSource
        When you use the PassThru parameter, Set-TraceSource generates a System.Management.Automation.PSTraceSource object representing the trace session. Otherwise, this cmdlet does not generate any output.

NOTES

        Tracing is a method that developers use to debug and refine programs. When tracing, the program generates detailed messages about each step in its internal processing.

        The Windows PowerShell tracing cmdlets are designed to help Windows PowerShell developers, but they are available to all users. They let you monitor nearly every aspect of the Functionality of Windows PowerShell.

        A “trace source” is the part of each Windows PowerShell component that manages tracing and generates trace messages for the component. To trace a component, you identify its trace source.

        A “trace listener” receives the output of the trace and displays it to the user. You can elect to send the trace data to a user-mode or kernel-mode debugger, to the console, to a file, or to a custom listener derived from the System.Diagnostics.TraceListener class.

        To start a trace, use the Name parameter to specify a trace source (the component to be traced) and the FilePath, Debugger, or PSHost parameters to specify a listener (a destination for the output). Use the Options parameter to determine the types of events that are traced and the ListenerOptions parameter to configure the trace output.

        To change the configuration of a trace, enter a Set-TraceSource command as you would to start a trace. Windows PowerShell recognizes that the trace source is already being traced. It stops the trace, adds the new configuration, and starts or restarts the trace.

        To stop a trace, use the RemoveListener parameter. To stop a trace that uses the file listener (a trace started by using the -FilePath parameter), use the RemoveFileListener parameter. When you remove the listener, the trace stops.

        To determine which components can be traced, use Get-TraceSource. The trace sources for each module are loaded automatically when the component is in use, and they appear in the output of Get-TraceSource.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Set-TraceSource -Name Parameterbinding -Option ExecutionFlow -PSHost ‘
    -ListenerOption “ProcessID,TimeStamp”

    Description
    ———–
    This command starts tracing for the ParameterBinding component of Windows PowerShell. It uses the Name parameter to specify the trace source, the Option parameter to select the ExecutionFlow trace events, and the PSHost parameter to select the Windows PowerShell host listener, which sends the output to the console. The ListenerOption parameter adds the “ProcessID” and “TimeStamp” values to the trace message prefix.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Set-TraceSource -Name ParameterBinding -RemoveListener Host

    Description
    ———–
    This command stops the trace of the ParameterBinding component of Windows PowerShell. It uses the Name parameter to identify the component that was being traced and the RemoveListener parameter to identify the trace listener.

Set-Acl

NAME
    Set-Acl

SYNOPSIS
    Changes the security descriptor of a specified resource, such as a file or a Registry key.

SYNTAX
    Set-Acl [-Path] <string[]> [-AclObject] <ObjectSecurity> [-Exclude <string[]>] [-Filter <string>] [-Include <string[]>] [-Passthru] [-Confirm] [-WhatIf] [-UseTransaction] [<CommonParameters>]

DESCRIPTION
    The Set-Acl cmdlet changes the security descriptor of a specified resource, such as a file or a Registry key, to match the values in a security descriptor that you supply.

    To use Set-Acl, use the Path parameter to identify the resource whose security descriptor you want to change, and use the AclObject parameter to supply a security descriptor that has the values you want to apply. Set-Acl uses the value of the AclObject parameter as a model and changes the values in the resource’s security descriptor to match the values in the AclObject parameter.

PARAMETERS
    -AclObject <ObjectSecurity>
        Specifies an ACL with the desired property values. Set-Acl changes the ACL of resource specified by the Path parameter to match the values in the specified security object.

        You can save the output of a Get-Acl command in a Variable and then use the AclObject parameter to pass the Variable, or type a Get-Acl command.

        Required?                    true
        Position?                    2
        Default value
        Accept pipeline input?     true (ByValue)
        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

    -Include <string[]>
        Changes 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

    -Passthru [<SwitchParameter>]
        Returns an object representing the security descriptor. By default, this cmdlet does not generate any output.

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

    -Path <string[]>
        Identifies the resource whose security descriptor you want to change. Enter the path to a resource, such as a path to a file or Registry key. Wildcards are permitted.

        If you pass a security object to Set-Acl (either by using the AclObject parameter or by passing an object from Get-Acl to Set-Acl), and you omit the Path parameter (name and value), Set-Acl uses the path that is included in the security object.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?     true (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.Security.AccessControl.ObjectSecurity
        You can pipe a security descriptor to Set-Acl.

OUTPUTS
    None or security object
        By default, Set-Acl does not generate any output. However, if you use the -Passthru parameter, it generates a security object. The type of the security object depends on the type of the resource.

NOTES

        The Set-Acl cmdlet is supported by the Windows PowerShell file system and Registry providers. As such, you can use it to change the security descriptors of files, directories, and Registry keys.

        When specifying multiple values for a parameter, use commas to separate the values. For example, “<parameter-name> <value1>, <value2>”.

    ————————– EXAMPLE 1 ————————–

    C:\PS>$DogACL = Get-Acl c:\dog.txt

    C:\PS>Set-Acl -Path C:\cat.txt -AclObject $DogACL

    Description
    ———–
    These commands copy the values from the security descriptor of the Dog.txt file to the security descriptor of the Cat.txt file. When the commands complete, the security descriptors of the Dog.txt and Cat.txt files are identical.

    The first command uses the Get-Acl cmdlet to get the security descriptor of the Dog.txt file. The assignment operator (=) stores the security descriptor in the value of the $DogACL Variable.

    The second command uses Set-Acl to change the values in the ACL of Cat.txt to the values in $DogACL.

    The value of the Path parameter is the path to the Cat.txt file. The value of the AclObject parameter is the model ACL, in this case, the ACL of Dog.txt as saved in the $DogACL Variable.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Get-Acl c:\dog.txt | Set-Acl -Path C:\cat.txt

    Description
    ———–
    This command is almost the same as the command in the previous example, except that it uses a pipeline operator to send the security descriptor retrieved in a Get-Acl command to a Set-Acl command.

    The first command uses the Get-Acl cmdlet to get the security descriptor of the Dog.txt file. The pipeline operator (|) passes an object that represents the Dog.txt security descriptor to the Set-Acl command.

    The second command uses Set-Acl to apply the security descriptor of Dog.txt to Cat.txt. When the command completes, the ACLs of the Dog.txt and Cat.txt files are identical.

    ————————– EXAMPLE 3 ————————–

    C:\PS>$newACL = Get-Acl file0.txt

    C:\PS>Get-ChildItem c:\temp -recurse -Include *.txt -force | Set-Acl -AclObject $newacl

    Description
    ———–
    These commands apply the security descriptors in the File0.txt file to all text files in the C:\Temp directory and all of its subdirectories.

    The first command gets the security descriptor of the File0.txt file in the current directory and uses the assignment operator (=) to store it in the $newACL Variable.

    The first command in the pipeline uses the Get-ChildItem cmdlet to get all of the text files in the C:\Temp directory. The Recurse parameter extends the command to all subdirectories of C:\temp. The Include parameter limits the files retrieved to those with the “.txt” file name extension. The Force parameter gets hidden files, which would otherwise be excluded. (You cannot use “c:\temp\*.txt”, because the Recurse parameter works on directories, not on files.)

    The pipeline operator (|) sends the objects representing the retrieved files to Set-Acl command, which applies the security descriptor in the AclObject parameter to all of the files in the pipeline.

    In practice, it is best to use the Whatif parameter with all Set-Acl commands that can affect more than one resource. In this case, the second command in the pipeline would be “Set-Acl -AclObject $newacl -WhatIf“. This command lists the files that would be affected by the command. After reviewing the result, you can run the command again without the Whatif parameter.

    <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
    None or System.Management.Automation.AliasInfo
        When you use the PassThru parameter, Set-Alias generates a System.Management.Automation.AliasInfo object representing the Alias. Otherwise, this cmdlet does not generate any output.

NOTES

        An Alias is an alternate name or nickname for a cmdlet or command element. To run the cmdlet, you can use its full name or any valid Alias. For more information, see about_aliases.

        To create a new Alias, use Set-Alias or New-Alias. To delete an Alias, use Remove-Item.

        A cmdlet can have multiple Aliases, but an Alias can only be associated with one cmdlet at a time. If you use Set-Alias to associate the Alias with a different cmdlet, it is no longer associated with the original cmdlet.

        You can create an Alias for a cmdlet, but you cannot create an Alias for a command with parameters and values. For example, you can create an Alias for Set-Location, but you cannot create an Alias for “Set-Location C:\Windows\System32″. To create an Alias for a command, create a Function that includes the command, and then create an Alias to the Function.

        To save the Aliases from a session and use them in a different session, add the Set-Alias command to your Windows PowerShell profile. Profiles do not exist by default. To create a profile in the path stored in the $profile Variable, type “New-Item -type file -Force $profile”. To see the value of the $profile Variable, type “$profile”.

        You can also save your Aliases by using Export-Alias to copy the Aliases from the session to a file, and then use Import-Alias to add them to the Alias list for a new session.

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

    ————————– EXAMPLE 1 ————————–

    C:\PS>Set-Alias -Name list -Value Get-ChildItem

    Description
    ———–
    This command creates the Alias “list” for the Get-ChildItem cmdlet. After you create the Alias, you can use “list” in place of “Get-ChildItem” at the command line and in scripts.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Set-Alias list Get-Location

    Description
    ———–
    This command associates the Alias “list” with the Get-Location cmdlet. If “list” is an Alias for another cmdlet, this command changes its association so that it now is the Alias only for Get-Location.

    This command uses the same format as the command in the previous example, but it omits the optional parameter names, -Name and -Value. When you omit parameter names, the values of those parameters must appear in the specified order in the command. In this case, the value of -Name (“list”) must be the first parameter and the value of -Value (“Get-Location“) must be the second parameter.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Set-Alias scrub Remove-Item -Option readonly -PassThru | Format-List

    Description
    ———–
    This command associates the Alias “scrub” with the Remove-Item cmdlet. It uses the “ReadOnly” option to prevent the Alias from being deleted or assigned to another cmdlet.

    The PassThru parameter directs Windows PowerShell to pass an object that represents the new Alias through the pipeline to the Format-List cmdlet. If the PassThru parameter were omitted, there would be no output from this cmdlet to display (in a list or otherwise).

    ————————– EXAMPLE 4 ————————–

    C:\PS>Set-Alias np c:\windows\notepad.exe

    Description
    ———–
    This command associates the Alias, “np”, with the executable file for Notepad. After the command completes, to open Notepad from the Windows PowerShell command line, just type “np”.

    This example demonstrates that you can create Aliases for executable files and elements other than cmdlets.

    To make the command more generic, you can use the “Windir” Environment Variable (${env:windir}) to represent the C\Windows directory. The generic version of the command is “Set-Alias np ${env:windir}\notepad.exe”.

    ————————– EXAMPLE 5 ————————–

    C:\PS>function CD32 {Set-Location c:\windows\system32}

    C:\PS>Set-Alias go cd32

    Description
    ———–
    These commands show how to assign an Alias to a command with parameters, or even to a pipeline of many commands.

    You can create an Alias for a cmdlet, but you cannot create an Alias for a command that consists of a cmdlet and its parameters. However, if you place the command in a Function or a script, then you can create a useful Function or script name and you can create one or more Aliases for the Function or script.

    In this example, the user wants to create an Alias for the command “Set-Location c:\windows\system32″, where “Set-Location” is a cmdlet and “C:\Windows\System32” is the value of the Path parameter.

    To do this, the first command creates a Function called “CD32” that contains the Set-Location command.

    The second command creates the Alias “go” for the CD32 Function. Then, to run the Set-Location command, the user can type either “CD32” or “go”.

cmdlet, Content, Set

Set-Content

NAME
    Set-Content

SYNOPSIS
    Writes or replaces the content in an item with new content.

SYNTAX
    Set-Content [-LiteralPath] <string[]> [-Value] <Object[]> [-Credential <PSCredential>] [-Exclude <string[]>] [-Filter <string>] [-Force] [-Include <string[]>] [-PassThru] [-Confirm] [-WhatIf] [-UseTransaction] [<CommonParameters>]

    Set-Content [-Path] <string[]> [-Value] <Object[]> [-Credential <PSCredential>] [-Exclude <string[]>] [-Filter <string>] [-Force] [-Include <string[]>] [-PassThru] [-Confirm] [-WhatIf] [-UseTransaction] [<CommonParameters>]

DESCRIPTION
    The Set-Content cmdlet is a string-processing cmdlet that writes or replaces the content in the specified item, such as a file. Whereas the Add-Content cmdlet appends content to a file, Set-Content replaces the existing content. You can type the content in the command or send content through the pipeline to Set-Content.

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 set the contents of a file, even if the file is read-only. 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[]>
        Changes 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 item that will receive the content. 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

    -PassThru [<SwitchParameter>]
        Returns an object representing the content. By default, this cmdlet does not generate any output.

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

    -Path <string[]>
        Specifies the path to the item that will receive the content. Wildcards are permitted.

        Required?                    true
        Position?                    1
        Default value

        Accept wildcard characters? false

    -Value <Object[]>
        Specifies the new content for the item.

        Required?                    true
        Position?                    2
        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.Object
        You can pipe an object that contains the new value for the item to Set-Content.

OUTPUTS
    None or System.String
        When you use the Passthru parameter, Set-Content generates a System.String object representing the content. Otherwise, this cmdlet does not generate any output.

NOTES

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

        Set-Content is designed for string processing. If you pipe non-string objects to Set-Content, it converts the object to a string before writing it. To write objects to files, use Out-File.

        The Set-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>Set-Content -Path C:\Test1\test*.txt -Value “Hello, World”

    Description
    ———–
    This command replaces the contents of all files in the Test1 directory that have names beginning with “test” with “Hello, World”. This example shows how to specify content by typing it in the command.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Get-Date | Set-Content C:\Test1\date.csv

    Description
    ———–
    This command creates a comma-separated Variable-length (csv) file that contains only the current date and time. It uses the Get-Date cmdlet to get the current system date and time. The pipeline operator passes the result to Set-Content, which creates the file and writes the content.

    If the Test1 directory does not exist, the command fails, but if the file does not exist, the command will create it.

    ————————– EXAMPLE 3 ————————–

    C:\PS>(Get-Content Notice.txt) | ForEach-Object {$_ -replace “Warning”, “Caution”} | Set-Content Notice.txt

    Description
    ———–
    This command replaces all instances of “Warning” with “Caution” in the Notice.txt file.

    It uses the Get-Content cmdlet to get the content of Notice.txt. The pipeline operator sends the results to the ForEach-Object cmdlet, which applies the expression to each line of content in Get-Content. The expression uses the “$_” symbol to refer to the current item and the Replace parameter to specify the text to be replaced.

    Another pipeline operator sends the changed content to Set-Content which replaces the text in Notice.txt with the new content.

    The parentheses around the Get-Content command ensure that the Get operation is complete before the Set operation begins. Without them, the command will fail because the two Functions will be trying to access the same file.

cmdlet, Item, Rename

Rename-Item

NAME
    Rename-Item

SYNOPSIS
    Renames an item in a Windows PowerShell provider namespace.

SYNTAX
    Rename-Item [-Path] <string> [-NewName] <string> [-Credential <PSCredential>] [-Force] [-PassThru] [-Confirm] [-WhatIf] [-UseTransaction] [<CommonParameters>]

DESCRIPTION
    The Rename-Item cmdlet changes the name of a specified item. This cmdlet does not affect the content of the item being renamed.

    You cannot use Rename-Item to move an item, such as by specifying a path along with the new name. To move and rename an item, use the Move-Item cmdlet.

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

    -Force [<SwitchParameter>]
        Allows the cmdlet to rename items that cannot otherwise be changed, such as hidden or read-only files or read-only Aliases or Variables. The cmdlet cannot change constant Aliases or Variables. 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

    -NewName <string>
        Specifies the new name of the item. Enter only a name, not a path and name. If you enter a path that is different from the path that is specified in the Path parameter, Rename-Item generates an error. To rename and move an item, use the Move-Item cmdlet.

        You cannot use wildcard characters in the value of NewName. To specify a name for multiple files, use the Replace operator in a regular expression. For more information about the Replace operator, type “Get-Help about_Comparison_Operators“. For a demonstration, see the examples.

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

    -PassThru [<SwitchParameter>]
        Passes an object representing the item to the pipeline. By default, this cmdlet does not generate any output.

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

    -Path <string>
        Specifies the path to the item to rename.

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

    -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 string that contains a path to Rename-Item.

OUTPUTS
    None or an object representing the renamed item.
        When you use the Passthru parameter, Rename-Item generates an object representing the renamed item. Otherwise, this cmdlet does not generate any output.

NOTES

        The Rename-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>Rename-Item -Path c:\logfiles\daily_file.txt -NewName monday_file.txt

    Description
    ———–
    This command renames the file daily_file.txt to monday_file.txt.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Rename-Item -Path project.txt -NewName d:\archive\old-project.txt

    Rename-Item : Cannot rename because the target specified represents a path or device name.
    At line:1 char:12
    + Rename-Item <<<< -Path project.txt -NewName d:\archive\old-project.txt
        + CategoryInfo         : InvalidArgument: (:) [Rename-Item], PSArgumentException
        + FullyQualifiedErrorId : Argument,Microsoft.PowerShell.Commands.RenameItemCommand

    C:\PS> Move-Item -Path project.txt -destination d:\archive\old-project.txt
    # Command succeeds

    Description
    ———–
    This example shows that you cannot use the Rename-Item cmdlet to both rename and move an item. Specifically, you cannot supply a path for the value of the NewName parameter, unless the path is identical to the path specified in the Path parameter. Otherwise, only a new name is permitted.

    The first command uses the Rename-Item cmdlet to rename the project.txt file in the current directory to old-project.txt in the D:\Archive directory. The result is the error shown in the output.

    The second command shows the correct way to move and rename a file by using the Move-Item cmdlet. The Move-Item cmdlet lets you specify both a new path and a new name in the value of its Destination parameter.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Rename-Item HKLM:\Software\MyCompany\Advertising -NewName Marketing

    Description
    ———–
    This command uses the Rename-Item cmdlet to rename a Registry key from Advertising to Marketing. When the command is complete, the key is renamed, but the Registry entries in the key are unchanged.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Get-ChildItem *.txt | Rename-Item -NewName { $_.name -replace ‘\.txt’,’.log’ }

    Description
    ———–
    This example shows how to use the Replace operator to rename multiple files, even though the NewName parameter does not accept wildcard characters.

    This command renames all of the .txt files in the current directory to .log.

    The command uses a Get-ChildItem cmdlet to get all of the files in the current directory that have a .txt file name extension. Then, it uses the pipeline operator (|) to send the resulting files to the Rename-Item cmdlet.

    In the Rename-Item command, the value of the NewName parameter is a script block that is executed before the value is submitted to the NewName parameter.

    In the script block, the $_ automatic Variable represents each file object as it comes to the command through the pipeline. The command uses the dot format (.) to get the Name property of each file object. The Replace operator replaces the “.txt” file name extension of each file with “.log”.

    Because the Replace operator works with regular expressions, the dot preceding “txt” is interpreted to match any character. To ensure that it matches only a dot (.), it is escaped with a backslash character (\). The backslash character is not required in “.log” because it is a string, not a regular expression.

        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.ServiceProcess.ServiceController, System.String
        You can pipe a service object or a string that contains a service name to Restart-Service.

OUTPUTS
    None or System.ServiceProcess.ServiceController
        When you use the PassThru parameter, Restart-Service generates a System.ServiceProcess.ServiceController object that represents the restarted service. Otherwise, this cmdlet does not generate any output.

NOTES

        Restart-Service can control services only when the current user has permission to do so. If a command does not work correctly, you might not have the required permissions.

        To find the service names and display names of the services on your system, type “Get-Service“. The service names appears in the Name column, and the display names appear in the DisplayName column.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Restart-Service wmi

    Description
    ———–
    This command restarts the Windows Management Instrumentation (WMI) service on the local computer.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Restart-Service -displayname net* -Exclude “net logon”

    Description
    ———–
    This command restarts the services that have a display name that begins with “Net”, except for the “Net Logon” service.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Get-Service net* | Where-Object {$_.Status -eq “Stopped”} | Restart-Service

    Description
    ———–
    This command starts all of the stopped network services on the computer.

    It uses the Get-Service cmdlet to get objects representing the services whose service name begins with “net”. (The optional Name parameter name is omitted.) The pipeline operator (|) sends the services object to the Where-Object cmdlet, which selects only the services with a status of “stopped.” Another pipeline operator sends the selected services to Restart-Service. In practice, you would use the WhatIf parameter to see the effect of the command before using it.

        “Get-Help about_CommonParameters“.

INPUTS
    System.ServiceProcess.ServiceController or System.String
        You can pipe a service object or a string that contains a service name to Resume-Service.

OUTPUTS
    None or System.ServiceProcess.ServiceController
        When you use the PassThru parameter, Resume-Service generates a System.ServiceProcess.ServiceController object representing the resumed service. Otherwise, this cmdlet does not generate any output.

NOTES

        The status of services that have been suspended is “Paused”. When services are resumed, their status is “Running”.

        Resume-Service can control services only when the current user has permission to do so. If a command does not work correctly, you might not have the required permissions.

        To find the service names and display names of the services on your system, type “Get-Service“. The service names appear in the Name column, and the display names appear in the DisplayName column.

    ————————– EXAMPLE 1 ————————–

    C:\PS>Resume-Service sens

    Description
    ———–
    This command resumes the System Event Notification service (the service name is represented in the command by “sens”) on the local computer. The command uses the Name parameter to specify the service name of the service, but the command omits the parameter name because the parameter name is optional.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Get-Service | Where-Object {$_.Status -eq “Paused”} | Resume-Service

    Description
    ———–
    This command resumes all of the suspended (paused) services on the computer. The first command gets all of the services on the computer. The pipeline operator (|) passes the results to the Where-Object cmdlet, which selects the services with a Status property of “Paused”. The next pipeline operator sends the results to Resume-Service, which resumes the paused services.

    In practice, you would use the WhatIf parameter to determine the effect of the command before running it without WhatIf.

    Description
    ———–
    These commands remove the local computer from the domain to which it is joined.

    The first command removes the computer from the domain. The command uses the Credential parameter to supply the credentials of a domain administrator. It uses the PassThru parameter and the Verbose common parameter to display information about the success or failure of the command.

    The second command uses the Restart-Computer cmdlet to restart the computer, which is required to complete the remove operation.

    The semi-colon (;) separates the two commands.
