[NCLUG] starting a script at startup as specific user?

[Gordon Forsythe]

Thanks, Mark.  Didn't know you could su to a specific user.  I'll look at
the named script and get it figured out from there.  BTW, you assume
correctly on the distro.

Apache actually starts as root, then becomes another user; who this other
user is is set in httpd.conf, so that's rather specific to apache.

If you're using RedHat, take a look at how named starts up:

daemon named -u named

the "-u" argument specifies the user to start as.

The "daemon" command isn't a normal bash command, but comes from
/etc/rc.d/init.d/functions (again, I'm assuming RedHat).  You might want
to use /etc/rc.d/init.d/named as an example.

Whether or not you're using RedHat, you can also do something simple like
this:

su user -c command_to_run

(This is essentially what the daemon() function does.)
