Not quite a fan of vi? Whilst it is important to know, you are not limited to using vi when using commands such as edquota, crontab, visudo, etc. You can change the default editor used if you like. The variable VISUAL controls the editor and all you need to do is set it to the path of your favorite editor.
To change the editor from vi to joe you would use:
The above command sets this variable for the current session only.
echo "export VISUAL=/usr/bin/joe" >> ~/.profile
The above command sets this variable for future logins.
