To implement Foreach-Object Parallel in Powershell, you can use the ForEach-Object -Parallel
parameter. This parameter is available in PowerShell version 5.0 and above.
Using this parameter, you can process multiple items in parallel, instead of one item at a time. The syntax for the command is as follows:
1ForEach-Object -InputObject <Object[]> -Parallel { <ScriptBlock> } Where <Object[]>
is the array of objects you want to process and <ScriptBlock>
is the script block containing the code to process each of the objects. For example, if you want to process a list of files in a directory, you can use the following command:
1Get-ChildItem -Path "C:\MyFolder" | ForEach-Object -Parallel { <ScriptBlock> } Where <ScriptBlock>
is the script block containing the code to process each file. You can also use the -ThrottleLimit
to limit the number of jobs running at the same time. For example, if you want to process 5 files in parallel, you can use the following command:
1Get-ChildItem -Path "C:\MyFolder" | ForEach-Object -Parallel -ThrottleLimit 5 { <ScriptBlock> }
By using the -Parallel parameter, you can greatly increase the speed at which you can process data in PowerShell.
