You can use the suid permissions bit.
But be very careful to not let your script be hijacked.

I think there might be an option to the "su" command which
will let you run a script as another user.  You can
then split your script into two parts, have the first part
do things and then call 

su -c power-user  "/home/bin/newscript"


Something like that.  My syntax is probably bad.

Subject: How do I elevate in a script?

Hi All,

I have a bash script that need to be run as root.
In the script, I check to see if it is running as
root and flag the user to run appropriately.

Is there a way to use "su" to prompt for the password
and continue the script if successful? (I would test for
$? after the prompt.)

Currently "su" will just open a new shell as root.

I can run a command inside "su", but what about the
other 200 lines of code?  :'(

Many thanks,
-T
