Programming and Scripting :: User commands in root script

Is there a way to execute some commands as user in a script called by root?

For example, in a script that requires to be run as root due to using "modprobe", is there a way to use "mydsl-load" as user?

su dsl mydsl-load ....

Aaah - thanks (don't recall seeing that anywhere).

use man su?

Anyways, I think using that way implies -c (the way I'm used to using it)
