How to grant permission for cron job file?

Question

I set the cron tab for my site. But I have a message in my inbox like "Permission denied" for a script. Can anyone help me tell me what could be the problem.

Thanks......

Answer 1

Are you getting this error when setting up crontab? or from a script running from cron?

If you are installing crontab, try the following:

You enter: crontab -e You get: - bash: / usr / bin / crontab: Permission denied

Problem: Your user is not in the cron group.

. root, /etc/group, cron          ( ).          .

: "". "cron".

, , SSH. , SSH, , cron .

My solution was to create an additional key for this script without a passphrase (using ssh-keygen), install it on a remote server, and specify ssh commands in the script with the -i flag.

ssh -i /path/to/id_rsa.no-passphrase user@remote command-to-run
