Calculates the numeric properties of objects, and the characters, words, and lines in string objects, such as files of text. (Measure-Object)
NAMEMeasure-ObjectSYNOPSISCalculates the numeric properties of objects, and the characters, words, and lines in string objects, such as files of text.SYNTAXMeasure-Object [-Average] [-Maximum] [-Minimum] [-Sum] [[-Property] <string[]>] [-InputObject <psobject>] [<CommonParameters>] Measure-Object [-Character] [-IgnoreWhiteSpace] [-Line] [-Word] [[-Property] <string[]>] [-InputObject <psobject>] [<CommonParameters>]DESCRIPTIONThe 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.PARAMETERS-Average [<SwitchParameter>] Displays the average value of the specified properties. Required? false Position? named Default value Accept pipeline input? false Accept wildcard characters? false -Character [<SwitchParameter>] Counts the number of characters in the input object. Required? false Position? named Default value Accept pipeline input? false Accept wildcard characters? false -IgnoreWhiteSpace [<SwitchParameter>] Ignores white space in word counts and character counts. By default, white space is not ignored. Required? false Position? named Default value Accept pipeline input? false Accept wildcard characters? false -InputObject <psobject> Specifies the objects to be measured. Enter a variable that contains the objects, or type a command or expression that gets the objects. Required? false Position? named Default value Accept pipeline input? true (ByValue) Accept wildcard characters? false -Line [<SwitchParameter>] Counts the number of lines in the input object. Required? false Position? named Default value Accept pipeline input? false Accept wildcard characters? false -Maximum [<SwitchParameter>] Displays the maximum value of the specified properties. Required? false Position? named Default value Accept pipeline input? false Accept wildcard characters? false -Minimum [<SwitchParameter>] Displays the minimum value of the specified properties. Required? false Position? named Default value Accept pipeline input? false Accept wildcard characters? false -Property <string[]> Specifies one or more numeric properties to measure. The default is the Count (Length) property of the object. Required? false Position? 1 Default value Count Accept pipeline input? false Accept wildcard characters? false -Sum [<SwitchParameter>] Displays the sum of the values of the specified properties. Required? false Position? named Default value Accept pipeline input? false Accept wildcard characters? false -Word [<SwitchParameter>] Counts the number of words in the input object. 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.

EXAMPLE 1C:\PS>get-childitem | measure-objectDescription----------- This command counts the files and folders in the current directory.EXAMPLE 2C:\PS>get-childitem | measure-object -property length -minimum -maximum -averageDescription----------- 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 3C:\PS>get-content C:\test.txt | measure-object -character -line -wordDescription----------- This command displays the number of characters, words, and lines in the Text.txt file.EXAMPLE 4C:\PS>get-process | measure-object -property workingset -minimum -maximum -averageDescription----------- This command displays the minimum, maximum, and average sizes of the working sets of the processes on the computer.EXAMPLE 5C:\PS>import-csv d:\test\serviceyrs.csv | measure-object -property years -minimum -maximum -averageDescription----------- 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 6C:\PS>get-childitem | measure-object -property psiscontainer -max -sum -min -average Count : 126 Average : 0.0634920634920635 Sum : 8 Maximum : 1 Minimum : 0 Property : PSIsContainerDescription----------- 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.
