Re: Running process as another user

Looking at perlvar for $< and $>, it suggests that you may want to call POSIX::setuid() to set both in one call. Would that work for you? Or would simply setting both, $< and $> work for you, too?

($<,$>)= ($run_as, $run_as);

use POSIX qw(setuid);

setuid( $run_as );

I actually mentioned in my post why this is not what I want. The problem with this approach is that the resulting process (while running under the correct effective user-id) still seems to be running as root in ps. I would like to have a process running under another effective id and be visible as such in ps.	[reply]

Ah - I'm sorry, I thought that one was for setting the real user-id in addition to the effective user-id would have that effect.	[reply]

Actually you were right (so I am sorry). What I tried before I posted my question here was setting $< and that makes the process still appear as being run by root. But setting $> does the trick and is all that is needed. Seems I need to brush up on real vs effective uid...	[reply]
