switching user in shell

Hi All,

I want to run a cronjob that uses a shell script.

The script simply does:

#!/bin/csh -f
su - sully
touch /apps/testfile
touch /data/testfile

Then chmod it so it executes.

The su to sully spawns a child I imagine and the touch commands then
try
and run as root, I think. Or the first touch runs a sully and the
second does not.
My root mail is saying permission denied on /data/testfile for
example, though
at the command line, as sully, I can do the touches.

Anyway....

How do I switch to sully, run the two touch commands, then exit or do
I do the
su in the cron.

Thanks

as soon as you do the "su - sully" as shown, you effectively leave
your script, so the touch is being hit. assuming you're running as
root a couple of possibilities come to mind:

su - sully -c /path_to_yourscript

if the entire thing can be run as "sully"

alternatively, change your script above such that it touches the
files, then sets required permissions, then does a chown so that sully
owns it if necessary. Based on what you've said above, I think I'd
go this route....and change to something other than csh
