Powershell: Perform an operation on all files in a directory (foreach)

Question

In bash, the equivalent would be

for x in `ls *.zip` do ; unzip $x ; done

How do I do this in Windows Powershell.

Update As Johannes Rössel pointed out this is a bad example (unzip *.zip) but what I'm after is the "foreachness" of it.

Answer 1

ls *.zip | foreach-object { unzip $_ }
