Running process as another userby morgon (Deacon)
|on May 14, 2014 at 09:35 UTC||Need Help??|
morgon has asked for the
wisdom of the Perl Monks concerning the following question:
I have a script that is started by udev and so runs as root. What I want the script to do is to fork off another long-running process that is supposed to run as another user.
Here is what I do at the moment:
This works but in the process table I end up with 2 processes: One for the started command running as some_other_id and a root-process for the sudo.
My question is now how to avoid having the sudo-process staying around.
To rephrase: How do you fork off a long-runnning process under an other user-id while avoiding a root-owned sudo-process staying around as well.
Please note that I want the new process to appear in the process-table as beloning to the other user, so setting effective uid does not do the trick as the process would still appear as root in ps.
