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>
