From a comment at http://www.davidarno.org/2008/04/08/pash-powershell-for-the-rest-of-us/:
With the ksh, I could type
whence -v cdto determine that
cdwas a tracked alias of say
/bin/cd. In PowerShell,
cdis an alias of
Set-Location, but I only found this out because I typed
help cd, and got the
Set-Locationhelp page. The
whence -vcommand would report whether the item was a function, alias, tracked alias, or give the file location.
How can we do this in PowerShell?
