Equivalent of *Nix 'which' command in 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 at the start of the last line is to ensure it will start as a new line.

Here is an actual *nix equivalent, i.e. it gives *nix-style output.

Get-Command <your command> | Select-Object -ExpandProperty Definition

Just replace with whatever you're looking for.

PS C:\> Get-Command notepad.exe | Select-Object -ExpandProperty Definition
C:\Windows\system32\notepad.exe

When you add it to your profile, you will want to use a function rather than an alias because you can't use aliases with pipes:

function which($name)
{
    Get-Command $name | Select-Object -ExpandProperty Definition
}

Now, when you reload your profile you can do this:

PS C:\> which notepad
C:\Windows\system32\notepad.exe
