Thanks for ur reply!!
So if I want to run my file "update.pl" weekly,
How should I write?
Becos, it is a perl script so I will need to run perl program ...... so in the filename side, should I write something like this -> perl update.pl
and the timimg will be -> *****/Mon
so the overall will look like that -> *****/Mon perl /home/kelvin/update.pl
is that correct?
And btw, where should I put this line of code becos my system don't have crontab, instead, it have cron.d, cron.daily, cron.weekly, etc......
Should I activate the CRON command to start running the above code?
