How do I create a script that will restart another script after so many minutes?
« on: February 08, 2012, 05:10:20 pm »
Okay I have OmnomIRC running in my channels which keeps closing now apparently it needs an auto restart script according to Nathem. How do I create one? I tried Googling but had no success what so ever. Is this in the wrong place or is there a better place for it?

You could just do something like this:
Code: [Select]
p="process name"
while true; do
/path/to/process/to/run;
while [ "$(ps -C $p | grep $p)" != "" ]; do
sleep 3;
done;
done;I haven't tested it but with some tweaking I'm pretty sure it should do what you want.

Well if I remember correctly it would probably be the name of the script/binary you are running. You could try changing it to ps -A instead, it's just less precise.

I've tried looking through ps -A in the past only to find that my bots process names are "PHP". Any way of changing a process name for a bot?

Netham45 appears to have the same problems for his OmnomIRC it seems. I wonder if your script could actually fix our split channel problems Eeems? (so we don't have to rely on AaronBot or Jimbauwen every few week or so)

You seriously rely on AaronBot? :o That thing is buggy! I used it as a relay and it kept getting mixed up and ended up relaying other peoples channels to mine.

You could modify the php script to write its pid to a file each startup.

It didn't seem too bad last night, although when Alberthrocks modified it at one point it started freaking out. We only rely on AaronBot when Jimbauwen is not online.

You could do the pid thing. You could also run the script itself ( ./OmnomIRC.php ( make sure to add the right stuff to the start of it ( #!/usr/bin/php5 ) ) ) that way the process name will be the name of the script instead of php :)

EDIT: @ DJ: my script probably wont fix the issues where omnom stops relaying to one of the channels. That is a code issue I think. Unless he has multiple processes ( one per server he connects to ).

I think he already has an auto-restart script. I'm not sure though, we'd have to ask him.
Oh, and btw helen, this script will also start Omnom on its own if it isn't running. You can start it first or just my script, it doesn't really matter.
