cronjobs and perl scripts

[BlackFox]

okay, i have this perl script for SigX and im trying to put a new line into my crontab file in my /etc folder so that itll execute the perl script every 2 miniutes. this is the line i added to the crontab file

0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58 * * * * /etc/SigX.pl >/dev/null 2>&1

im just wondering if i did the right thing, if not someone correct me. this isnt as easy as it was in windows lol.
im also posting the SigX script just so you can look over it and tell me if theres anything wrong with it, or if theres anything i need for it to run.

so thats it, im just looking for a little help, hopefully someone here has already done this and knows how to. thanks guys.

**edit**
also i try and run the SigX.pl file by typing "sh SigX.pl" in my console and this is the message i get.

[blackfox@21-130 etc]$ sh SigX.pl

Well, you will have to fix that script first..

Also:

0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,3 6,38,40,42,44,46,48,50,52,54,56,58 * * * * /etc/SigX.pl >/dev/null 2>&1

Did you know that you can simplify that to..

*/2 * * * * /etc/SigX.pl >/dev/null 2>&1

[BlackFox]

clarification = i dont know what the **** im doing, thats why im trying to ask for help. if i knew how to fix it, i wouldnt be posting asking for help...

[serz]

Wait a sec, that's a Perl script and you're using "sh script", treating it as it if was a shell script.

Try /usr/bin/perl SigX.pl instead.

[BlackFox]

okay, that helps a bit, i didnt quite realize what the sh command was, so heres the latest.

[blackfox@21-130 etc]$ /usr/bin/perl SigX.pl

*edit* can a moderator move this to the scripting section, i didnt notice it untill after i had made the inital post, and im not about to cross post and waste forum space. thanks.
