Crontab

Some time ago I posted a crontab entry that starts up the mud if it is down.
That crontab entry works fine on a SGI computer, now I have moved to a 
linux computer and had to change my crontab entry (because of the other ps 
options).

It is now: (must be 1 line)
0,5,10,15,20,25,30,35,40,45,50,55 * * * * if [ -z "`ps -x|grep -v 
grep|grep circle`" ]; then cd ~user/muddir; bin/circle 4000 >& 
syslog& fi

You see I curently don't use autorun, if you do it has to be something like:
(again on 1 line)
0,5,10,15,20,25,30,35,40,45,50,55 * * * * if [ -z "`ps -x|grep -v 
grep|grep circle`" ] && [ -z "`ps -x|grep -v grep|grep autorun`"];
then cd ~user/muddir; autorun& fi

(this only starts autorun if there is no circle and no autorun running, 
it checks every 5 minutes)

I keep this line in a file named .crontab in my home dir, to activate it 
I use "crontab .crontab" but there are other ways of doing this.

There are no other scripts needed.

All output is mailed to you (so make sure there is no output) ;)

You can check your current crontab entries with "crontab -l".

Greeting,
Jaco
