How do I exit vi editor after saving?

The lowly and now middle-aged vi editor is still a favorite among *nix system administrators and remains an essential tool for command-line file creation and editing.

Gray at the temples and in need of reading glasses, the middle-aged Vi (pronounced vee-eye) editor, released in 1976, is still a system administrator's best friend.

This advanced, yet simple to use, command-line editing program shows no sign of slowing down. You can use it to edit configuration files, create a grocery list, write a letter home to ask for money, create a new script, or even edit source code. 

Vi is often a symbolic link to Vim (Vi Improved) or an alias to Vim, an enhanced version of Vi.

It’s easy to invoke Vi. At the command line, you type vi to create a new file, or to edit an existing one.

$ vi filename.txt

Vi edit modes

The Vi editor has two modes: Command and Insert. When you first open a file with Vi, you are in Command mode. Command mode means you can use keyboard keys to navigate, delete, copy, paste, and do a number of other tasks—except entering text.

To enter Insert mode, press i. In Insert mode, you can enter text, use the Enter key to go to a new line, use the arrow keys to navigate text, and use vi as a free-form text editor. To return to Command mode, press the Esc key once.

In Vi's Command mode, almost every letter on the keyboard has a function.

To save a file, you must first be in Command mode. Press Esc to enter Command mode, and then type :wq to write and quit the file. The other, quicker option is to use the keyboard shortcut ZZ to write and quit. In Vi, write means save, and quit means exit. If you’ve made mistakes along the way while editing and want to back out (abandon) all non-saved changes, enter Command mode by pressing Esc and typing :q! This command quits without saving any changes and exits Vi.

Note: Always make a copy of an existing file prior to editing with Vi or any editor. This is especially critical when editing system and configuration files.
