Problem
Exiting a file in vi.
Solution
There are quite a few ways to exit a file in vi. Here are some of my favorites.
Example
The standard: :wq
Force, in the case of read-only: :wq!
Abort updates: :q!
Reset the file without writing: :e!
Quick save and exit: 😡
Lazy one, without using a colon: ZZ
Going to another file: n filename
Go back to the first file, when you'v edited with wildcard or list of files: :rew
