using su with -c option

[osu250]

I need to run a script that su's to diff user and then runs a command as the second user. I think the way to do this is using -c option on su but I can't seem to get it to work. Can anyone provide me with sample code / syntax ?

I am running Red Hat Linux
Thanks in advance!

su UserName -c "command to execute"

Hope This Helps, PH.

Keep in mind the su - <user> and su <user>

Excerpts from man page for su

If the first argument to su is a ``-'', the environment is changed to what would be expected if the user actually logged in as the specified user. This is done by invoking the program used as the shell with an arg0 value whose first character is ``-'', thus causing first the system's profile (/etc/profile) and then the specified user's profile (.profile in the new $HOME directory) to be executed.

cdlvj makes a good point and this is particularly important when setting up cron jobs - see the myriad questions in these fora concerning that issue!!
