$EDITOR

1 min read · system

The System's default text editor can be defined within /etc/profile. It's given the variable EDITOR.

Add these lines to /etc/profile.d/custom.sh:

1echo 'export EDITOR=vim' >> /etc/profile.d/custom.sh
2echo 'export VISUAL=$EDITOR' >> /etc/profile.d/custom.sh

Then reload that profile with:

1source /etc/profile

If you want to ensure nano never appears again:

1sudo ln -sf $(which vim) $(which nano)
