Know everything about nano Text Editor Print

  • Linux, text editor, nano, commands
  • 2

Once you have connected to your Linux ssh account, you will need to access a text editor to write the code. There are a few already installed on the system (vi, emacs, etc.), but these have a bit of a learning curve associated with them. Nano is a relatively easy editor to use, but you have to operate it entirely from the keyboard, so you'll have to learn some keyboard commands. Fortunately, they're pretty quick and easy to learn!

NOTE: Any command prefixed with a caret symbol (^) means to use the Ctrl key (e.g., ^G means to press the Ctrl+g keys at the same time). Any command prefixed with the letter M means to press the Alt key (e.g., M-R means to press the Alt+r keys together)..

Nano Keyboard Commands

If you take a look at the online help in nano (Ctrl+G) you'll be presented with a list of the commands available. For your convenience, I've duplicated that list below; the ones I think are most important are marked with three asterisks.

NOTE: Any command prefixed with a caret symbol (^) means to use the Ctrl key (e.g., ^G means to press the Ctrl+G keys at the same time). Any command prefixed with the letter M means to press the Alt key (e.g., M-R means to press the Alt+R keys together).
