My favorite editor is vim, but some others prefer nano, or emacs, nano reminds me WordStar, anyway.

Cron job default editor which is invoqued by the command crontab -e is vi, while I prefer vim, and you may prefer nano, you can use this command.

env EDITOR=nano crontab -e

or as I usually do:

env EDITOR=vim crontab -e

You can create an alias</p>
