Change default crontab editor to nano in FreeBSD

When I edit the crontab using crontab -e it opens the crontab in vi. I'd prefer it to use nano. How can I change this?

EDIT:

For some reason the export command returns command not found. And changing the EDITOR env value didn't work for crontab -e.

The following command worked on my system:

setenv VISUAL /usr/local/bin/nano

For sh based shells:

export EDITOR=/path/to/nano

For C shell based:

setenv EDITOR /path/to/nano

Remember that unless you save these setting to your login profile script (/home/user/.bash_profile for example), you lose the setting at log out.

If I remember correctly, FreeBSD uses C shell as the default user shell.

Should be

export EDITOR=/usr/bin/nano

adjust for your location of nano (use 'which' to find). You can put that command in your .bashrc or similar profile script to have it in effect all the time.
