I can't seem to find anything about a Powershell equivalent of the where command from cmd. Should I just call it from cmd or is there something more elegant in PS?

This question came from our site for system and network administrators.


Use the Get-Command commandlet passing it the name of the executable. It populates the Path property of the returned object (of type ApplicationInfo) with the fully resolved path to the executable.

# ~> (get-command notepad.exe).Path

    If you find yourself using this a lot, you can abbreviate the command as gcm instead of typing the whole Get-Command word every time – Moshe Katz Nov 18 '13 at 20:38
  • @MosheKatz Thank you! gcm notepad has been working perfect for me when I just want to see which file am I calling. – Shawn Wang Jul 28 '17 at 18:07
  • And this, boys and girls, is how you over-complicate useful things that were already right. If it isn't broken, don't fix it. – AFP_555 Apr 18 '18 at 14:39

If you're just looking to have the same functionality without invoking cmd, you can call where.exe from powershell, as long as C:\Windows\System32 is in your path. The command where (without the .exe) is aliased to Where-Object, so just specify the full name.

PS C:\Users\alec> where
cmdlet Where-Object at command pipeline position 1

PS C:\Users\alec> where.exe
The syntax of this command is:

WHERE [/R dir] [/Q] [/F] [/T] pattern...

Get-ChildItem C:\SomeDir -Recurse *.dll

That's pretty much what the old where.exe does... was there more specific functionality that you're trying to mimic?

Edit: In response to Joshua's comment... oh, you want to search your PATH environment variables too? No problem.

Foreach($_ In $Env:Path -Split ';')
    Get-ChildItem $_ -Recurse *.dll

    "where" also searches the PATH as well – Joshua McKinnon Nov 13 '13 at 0:38

    oh, you want to search your PATH environment variables too? Um, yes, that’s the whole point to where, otherwise you can just use dir. Der. :-P – Synetech Nov 19 '13 at 2:26
