SET$EDITOR

Set $EDITOR

In Linux and other Unix-like operating systems, the EDITOR environment variable is used to specify the default text editor that should be used when opening and editing files from the command line.

The set EDITOR=nano command is used to set the EDITOR environment variable to the nano text editor. This means that any command or program that requires a text editor to be opened, such as git commit, will now use nano as the default editor instead of the previously set default.

The nano editor is a simple, easy-to-use text editor that is designed to be user-friendly and intuitive, making it a good choice for beginners who are new to Linux.

Setting the EDITOR environment variable to nano can be useful for users who prefer to use nano as their default text editor, or for users who are not familiar with other text editors like vi or emacs.

To make the EDITOR environment variable persist across terminal sessions, you can add the set EDITOR=nano command to your shell startup file, such as .bashrc or .zshrc, depending on which shell you are using.

To see if EDITOR as already be assigned:
echo $EDITOR

To set environment variable:
set EDITOR=nano

To unset use:
unset EDITOR

Now you can use $EDITOR /home/$USER/somefile.txt and it will open using nano or any other editor you set.
