Isso foi perguntado e respondido no Stack Overflow: Equivalente ao * Nix ', que 'comando em Powershell?
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 is to ensure it will start as a new line.
