Re: Perl Script as a Cron Job
The Answers are 1. Is /scripts/.pl the full path name? Yes the above is the correct path of the script : when i run perl /scripts/xxx.pl it runs fine 2. Does your script have execute permissions Yes it has execute permissions (i changed it chmod +x for the code file) 3. Does the shebang line indicate the full path to the perl binary?

This as to be the longest running thread since the great Good
answer/bad answer debate.
So Mazhar:
1) In who's crontab file have you put this entry?
2) Does this user exist in cron-allow?
3) Do you need to HUP crond to get the cron -rescheduled?
4) Have you any access to the cron log, if so what does that say?
5) Try printing out the environment variables at the start of the
script incase there is something restricting the job. Something like
the bit below (untested).
foreach my $k (%ENV) {
print $k - $ENV{$k}\n;
}
Is there any any output from the command, either from cron or from
the command line? Can we see a sample please and the output from the
above.
Thanx.

Dear DP,
Your answers to the questions above are here as follows,
1) In who's crontab file have you put this entry?
* In Root Login*
2) Does this user exist in cron-allow?
*Yes*
3) Do you need to HUP crond to get the cron -rescheduled?
*No*
4) Have you any access to the cron log, if so what does that say?
*How can i found the log file for cron job*
5) Try printing out the environment variables at the start of the
script incase there is something restricting the job. Something like
the bit below (untested).
foreach my $k (%ENV) {
print $k - $ENV{$k}\n;
}
*Attached is the file containing the output of the above script (op.log)*
Regards
Mazhar

Once you have worked out your crontab syntax, almost all cron problems are due to permissions or environment.
