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 command supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, OutBuffer, OutVariable, WarningAction, and WarningVariable. For more information, see about_CommonParameters.
Inputs and Outputs
The input type is the type of the objects that you can pipe to the cmdlet. The return type is the type of the objects that the cmdlet returns.
|
Inputs |
System.Management.Automation.PSObject You can pipe objects to Measure-Object. |
|
Outputs |
GenericMeasureInfo or TextMeasureInfoObject |
Example 1
| Copy Code |
|
|---|---|
C:\PS>get-childitem | measure-object |
|
Description
-----------
This command counts the files and folders in the current directory.
Example 2
| Copy Code |
|
|---|---|
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
| Copy Code |
|
|---|---|
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
| Copy Code |
|
|---|---|
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
| Copy Code |
|
|---|---|
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
| Copy Code |
|
|---|---|
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 (versus files) in the current directory.
