UnrealIRCd Forums

Any handy bash scripters here who could write up a script to check if the unrealircd process is running, if its not start it, if it is then exit the script Or does anyone know of any already exsisting? My purpose is to add a crontab job for this script.

I believe the ls command will return an error value if no files match the options. Something like?

See the ircdcron dir (ircdcron/ircdchk).

Wow i'm an idiot, thanks.

That will likely be true, but the existence of ircd.pid does not mean Unreal is running. I don't believe Unreal ever destroys ircd.pid, so all that file's existence signifies is that at one point in time Unreal was running.

Wouldnt ps aux | grep unrealircd do the trick? if it returns null, it aint running... Just a thought.

No it wouldn't. First off, it doesn't even get listed as "unrealircd" secondly, that just says _an_ Unreal is running. If you're on a shell account, there might be 10 ircds running. It doesn't mean your's is running.

Sorry to dig up this old thing...

ps x, by itself, should show "unhooked" processes (tty-less) that belong to the current user. Unless there are 500 people using the same login... using that should only show your ircd(s).

A useful trick if you're going to go the "ps | grep" route is to use egrep to avoid matching the grep itself.

Casual experimenting will lead to the discovery that "ps ux | grep ircd" will catch itself about half the time. Instead, I prefer to use something like this:
Using the brackets in an egrep will make the grep not match itself which will yield reliable results.

Or an alternative solution is to type ps x | grep ircd | grep -v grep.
