Text editing is essential to Linux users. Historically, the Vim text editor has been the default tool for managing file contents. Today, many systems and many sysadmins prefer to use the nano text editor.

This is the second article in a series that covers some essential Linux tools. My first article discusses: "The four things you must be able to do in Vim." It is a companion article to this one.

Nano is quite a bit more intuitive than Vim, but it's still worth taking a brief look at its most fundamental features. You must be able to accomplish the following four tasks with nano:

  • Create/open a file
  • Edit the file
  • Save changes
  • Exit the file

Create or open a file

To create a new file by using nano, type nano /path/filename. This is the same syntax Vim uses. The new file is created and opened for editing. To create a new file named "RHEL_versions," I type the following:

# nano ~/Documents/RHEL_versions

The file may now be edited. Nano does not use the concept of modes like Vim. Once the file opens in nano, if you type on the keyboard, text is inserted into the file.

Use the same command syntax to open an existing file, such as the "demo" file:

# nano ~/Documents/demo

Edit a file

Because nano does not use modes, you may begin editing the file immediately without navigating between Command mode and Insert mode. This certainly makes nano easier to use, but it also makes it less flexible. However, for basic file edits, such flexibility is often overkill.

Save a file

The Ctrl key activates nano's commands on your keyboard. There is an abbreviated list of commands displayed at the bottom of the nano interface, and these cover most basic needs. You "write out" a file to save its contents by using Ctrl+O.

Note: There are many additional commands available within nano that are not displayed in the primary menu.

Exit nano

If you examine the list of available commands at the bottom of nano's interface, you discover that you won't "quit" nano, but instead "exit" nano by using Ctrl+X.

Wrap up

In some ways, using nano is more like using the keyboard shortcuts in Microsoft Word or LibreOffice Writer. Nano is significantly more powerful than I am showing here, so be sure to check the documentation for more tricks. If you're a Vim user and you find yourself on a distribution that only has nano available, at least you'll know these simple functions.

I guess I'm old school (or just old), but I prefer Vim, even for very short and simple edits. I acknowledge that nano is easier, but I am in the habit of using Vim. In fact, I have it installed on my Mac and Windows computers, too.
