How to show line numbers in Nano on Mac

If you want to display the line numbers at the left-hand side gutter area in Nano editor on the Mac, then you can make use of the Keyboard Command: Esc + n

If for some reason you do not see any line numbers on the file, then you need to be aware that this does not work with the default Nano editor that is available with macOS. You will need to get the GNU version of Nano, you can get it using homebrew.

Install GNU Nano:

brew install nano

Also make sure to add the path to your .zshrc profile file, else you might be again using the default nano editor.

Path:

PATH="/opt/homebrew/bin/nano:$PATH"

Note: The path may vary based on your Mac CPU type M1/M2 or Intel.
