How do I ask PowerShell where something is?
For instance, "which notepad" and it returns the directory where the notepad.exe is run from according to the current paths.
The very first alias I made once I started customizing my profile in PowerShell was 'which'.
New-Alias which get-command
To add this to your profile, type this:
"`nNew-Alias which get-command" | add-content $profile
The `n at the start of the last line is to ensure it will start as a new line.
