Hi chefchanyu,

A few more diagnostics would be helpful.

I'm assuming /tmp/mycron.log gets updated? How exactly have you determined that your script isn't run?

Why is there a difference between the crontab entry you showed and the cron command from the logs? What happens when you try to run the exact crontab entry from the command line? ("date >> /tmp/mycron.log; perl /share/script/Test/report.pl /share/script/Test/file/ltm_all_non_prod")

Has cron sent you any e-mails? You can test this with a crontab entry that simply does "echo Hello", your root user should receive an e-mail, assuming that's been configured correctly. Look into whether your system has local mail delivery configured and at cron's MAILTO option (more detail in crontab(5)).

Hope this helps,
