su in a script?

[Gordon Keegan]

"su" will create a new shell with the owner you specify.  In
order to run something as that user, you need to specify:

    su quake3 -c "cd /usr/local/games/quake3; ./linuxq3ded ..."

and pass a single command to "su" to run as user "quake3", or
you can create a second script that has several commands and use:

    su quake3 -c "/usr/local/games/runquakescript"

(runquakescript has the "cd" and the "linuxq3ded" and whatever
commands you need in it.)

Also, if you have environment variables or aliases or anything
else that can be put into the ~quake3/.bashrc (or .profile),
you can use:

    su - quake3 -c "command_to_run"

The " - " tells "su" to run any login/profile/rc startup scripts
for the user "quake3".
