Cron Tips

(i actually made this because i was dumbfounded why my cron isn’t running)

Used crontab (user, not sudo or /etc/crontab) for doing things, and realize that things aren’t running.
So i’m browsing around and found these tips

Cron Stuff

• check permission for the file / folder, use

  ls -l [file / folder name]
  

  to check

• if not present, use

  chmod -x [file name]
  

  to add permission to execute
  (r - read, w - write, x - execute)

• add path to the cronjob list, use

  PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/home/[username]/[folder_file]
  

  to access path (untested)

• to get cron log (check if run)

  grep CRON /var/log/syslog
  

  or

  systemctl status cron
  

• add a command-specific before command-to-file

  0 * * * * /bin/bash [command]
  

  to make sure it uses bash / sh
