So I do a lot of work on a school computer. We can't install anything but we have most of our tools on our flash drives but I was wondering if there's a way to get Command Prompt to use Mercurial off of my Flash Drive. Let's say in theory that Mercurial's files were on my flash drive, where would I go from there?
To make Bryan's solution "truly" portable in Windows 2000/XP/Vista/7, assuming the BAT file is inside Mercurial's directory, use:
set PATH=%PATH%;%~dp0%
So, no more hardcoded paths.
