@Humpleupagus @r000t Completely ignoring the security ramifications in the process. Did he make sure to set the user and group to something appropriate and change it to read-only? Not doing that is a good way to have a future script inject hostile code into something that will be visible and accessible to the rest of the systems users, and thereby might be run by someone else.

This is why we have a $PATH var, so you can set a local folder to be included, and have that change only be user-wide.

Edit : If you want that change to stick, there is usually a . file that can be modified to push the change on each login.
