Running Shells as cronjobs

A common thing to do with a shell is making it run as a cronjob to clean up the database once in a while or send newsletters. This is trivial to setup, for example:

  */5  *    *    *    *  cd /full/path/to/app && Console/cake myshell myparam
# *    *    *    *    *  command to execute
# │    │    │    │    │
# │    │    │    │    │
# │    │    │    │    \───── day of week (0 - 6) (0 to 6 are Sunday to Saturday,
# |    |    |    |           or use names)
# │    │    │    \────────── month (1 - 12)
# │    │    \─────────────── day of month (1 - 31)
# │    \──────────────────── hour (0 - 23)
# \───────────────────────── min (0 - 59)
