Coming from Bash

If you're coming from Git Bash on Windows, then the external commands you're used to (bash, grep, etc) will not be available in nu by default (unless you had explicitly made them available in the Windows Path environment variable). To make these commands available in nu as well, add the following line to your with either append or prepend.

$env.Path = ($env.Path | prepend 'C:\Program Files\Git\usr\bin')

Note: this table assumes Nu 0.91.0 or later.
