how to stop a cron job - cpanel

Question

My cron job in my cpanel looks like this

cd public_html/Staging/ff; perl sendmail.pl >/dev/null

The sendmail.pl looks like this

my $php = `php decode.php`;

The decode.php looks like this

$user = "Hello";
$fh = fopen("output.txt","a+");
fwrite($fh,$user."\n");
fclose($fh);

output.txt file gets on updating every second, even though i've called it for 1 hour.

Now how do i stop this job based in PID?

Where should i find PID?

How do i find all cron jobs running right now? and stop it at once?

I wanted to call sendmail.pl every hour.

Answer 1

Since you have * in minute it now runs every minute. Try putting a value there (for instance 0) to run it every hour on that minute number. And only have star in hour.
