NAME
    Measure-Object

SYNOPSIS
    Calculates the numeric properties of objects, and the characters, words, and lines in string objects, such as files of text.

SYNTAX
    Measure-Object [-Average] [-Maximum] [-Minimum] [-Sum] [[-Property] <string[]>] [-InputObject <psobject>] [<CommonParameters>]

    Measure-Object [-Character] [-IgnoreWhiteSpace] [-Line] [-Word] [[-Property] <string[]>] [-InputObject <psobject>] [<CommonParameters>]

DESCRIPTION
    The Measure-Object cmdlet calculates the property values of certain types of object. Measure-Object performs three types of measurements, depending on the parameters in the command.
    The Measure-Object cmdlet performs calculations on the property values of objects. It can count objects and calculate the minimum, maximum, sum, and average of the numeric values. For text objects, it can count and calculate the number of lines, words, and characters.

    <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.Management.Automation.PSObject
        You can pipe objects to Measure-Object.

OUTPUTS
    GenericMeasureInfo or TextMeasureInfoObject

NOTES

    ————————– EXAMPLE 1 ————————–

    C:\PS>Get-ChildItem | Measure-Object

    Description
    ———–
    This command counts the files and folders in the current directory.

    ————————– EXAMPLE 2 ————————–

    C:\PS>Get-ChildItem | Measure-Object -Property length -Minimum -Maximum -Average

    Description
    ———–
    This command displays the minimum, maximum, and sum of the sizes of all files in the current directory, and the average size of a file in the directory.

    ————————– EXAMPLE 3 ————————–

    C:\PS>Get-Content C:\test.txt | Measure-Object -character -line -word

    Description
    ———–
    This command displays the number of characters, words, and lines in the Text.txt file.

    ————————– EXAMPLE 4 ————————–

    C:\PS>Get-Process | Measure-Object -Property workingset -Minimum -Maximum -Average

    Description
    ———–
    This command displays the minimum, maximum, and average sizes of the working sets of the processes on the computer.

    ————————– EXAMPLE 5 ————————–

    C:\PS>Import-Csv d:\test\serviceyrs.csv | Measure-Object -Property years -Minimum -Maximum -Average

    Description
    ———–
    This command calculates the average years of service of the employees of a company.

    The ServiceYrs.csv file is a CSV file that contains the employee number and years of service of each employee. The first row in the table is a header row of “EmpNo, Years”.

    When you use Import-Csv to import the file, the result is a PSCustomObject with note properties of EmpNo and Years. You can use Measure-Object to calculate the values of these properties, just like any other property of an object.

    ————————– EXAMPLE 6 ————————–

    C:\PS>Get-ChildItem | Measure-Object -Property psiscontainer -max -Sum -min -Average

    Count    : 126
    Average : 0.0634920634920635
    Sum     : 8
    Maximum : 1
    Minimum : 0
    Property : PSIsContainer

    Description
    ———–
    This example demonstrates the Measure-Object can measure Boolean values. In this case, it uses the PSIsContainer Boolean property to measure the incidence of folders (vs. files) in the current directory.
