How to use nano

Nano is a simple to use text editor.

Start it by typing nano on the command line, optionally followed by the name of a file to edit.

$ nano ~/public_html/index.html

Nano's editing commands are listed at the bottom of the screen. When you see a ^ character, it indicates the Ctrl key. So, for example, ^O Write Out means press Ctrl-O to save your work, and ^X Exit means press Ctrl-X to exit. Pretty straight forward!

Configuration

$ cp /etc/nanorc ~/.config/nano/nanorc

That command will copy the sample configuration file in your home directory. Now you can edit ~/.config/nano/nanorc to customize nano.

$ nano ~/.config/nano/nanorc

You can check the nanorc manpage for more information about certain options.

Notable options

set nowrap - disables text wrapping.
set linenumbers - enables line numbers. Their color can also be changed with set numbercolor fg,bg (see section named 'Changing colors' below).
set zap - makes it possible to highlight text and then remove it with a backspace.
set tabsize 4 - makes tabs smaller.
set mouse - enables mouse support.
set smooth - enables smooth scrolling.

Changing editor colors

Valid names for the foreground and background colors are: white, black, blue, green, red, cyan, yellow, magenta, and normal -- where normal means the default foreground or background color. The name of the foreground color may be prefixed with bright. And either "fgcolor" or ",bgcolor" may be left out.

set titlecolor fg,bg - Sets colors for the title bar (nano version, file being edited, etc.).
set numbercolor fg,bg - Sets colors for the line numbers (line numbers have to be enabled manually).
set keycolor fg,bg - Sets colors for the shortcut key combos in the help lines at the bottom.
set functioncolor fg,bg - Sets colors for the function descriptions in the help lines at the bottom.
set errorcolor fg,bg - Sets colors for the status bar when an error is displayed.
set statuscolor fg,bg - Sets colors for the status bar (displayed with Ctrl+C with normal keybinds).
set selectedcolor fg,bg - Sets colors for selected text.

Simpler keybindings

If you are used to common keybindings in graphical editors, append this to your nanorc:

bind ^Q exit all bind ^S savefile all bind ^F whereis all bind ^C cancel all bind ^Z undo all bind ^Y redo all bind M-U undo all bind M-Y redo all bind ^X cut all

If you're using a nano version higher or equal to 3.2, you can also add this after the other keybindings:

bind ^C copy main bind ^V paste all
