Using command as parameter in PowerShell

Question

I am trying to move some files to a relative subfolder recursivly.

I want to use the get-location command and combine it with a string ( "\foo_1" ), while using it as a parameter.

So get-location should result in " D:\foo_2 " so that the result is " D:\foo_2\foo_1 "

All while being a parameter of a separate command:

Get-ChildItem -Path ".\*.wav" -Recurse | Move-Item -Destination (get-location + "string")

I know i could just use variables, but i really want to understand this (if there is an answer). Thanks in advance =)

Answer 1

You could use a sub-expression, like this:

Get-ChildItem -Path ".\*.wav" -Recurse | 
    Move-Item -Destination "$(Get-Location)\foo_1"

The structure $(...) tells PowerShell to execute the contents of the brackets first (ie run Get-Location ) then substitute the result into the string. Note that you must use double-quotes as this functionality doesn't work with single-quoted strings.
