Execute multiple cmdlets in PowerShell

Question

How can I execute multiple commands in PowerShell on one line?

I am trying to unlock the files in the directory and output their names:

@"powershell get-childitem E:\\WRT\\Downloads\\TouchGesturesVisio -Recurse ^|select BaseName,Extension ^|unblock-file"

I need to be able to do this in a stand-alone application, but so far I can only get one cmdlet to function.

When I run the command from the application, I get the following exception.

powershell get-childitem E:\WRT\Downloads\TouchGesturesVisio -Recurse ^|select B
aseName,Extension ^|unblock-file
Error unblock-file : The input object cannot be bound to any parameters for the

I know about the option to use System.Management.Automation, but unfortunately it doesn't work on Windows 8.1. The assembly dependencies are messed up with Windows 8.1.

what app are you using to run the powershell? the errors you haven't tried my answer — Raf

Speechmarks are in the wrong place and you don't need to escape backslashes or use carets. If you are trying to unblock files you don't need the intermediate select either.

@powershell "get-childitem E:\WRT\Downloads\TouchGesturesVisio -Recurse |unblock-file"

I added the exception I get when I run the command. I had to escape the characters to allow the command to run on the console app.

your errors Error + ... ame,Extension |unblock-file show you are still using your original command rather than mine or @mjolinor's. try both and see how you get on

Does this work in your environment?

@powershell "get-childitem E:\WRT\Downloads\TouchGesturesVisio -Recurse -PipelineVariable File |unblock-file | ft @{l='Name';e={$File.basename}},Extension"

Still no dice, the files are getting unlocked, but I don't see the names.

This did it for me.

@"powershell Get-ChildItem 'E:\WRT\Downloads\TouchGesturesVisio' -Recurse -pv f ^| ForEach-Object {unblock-file $_.FullName -whatif}"

Thanks Raf and mjolinor for pointing me to the -PipleLineVariable
