於 Linux 最常使用的編輯器就是 VI、VIM，但是之前有流傳著，非常多人在 Stack Overflow 裡面發問，而問題就是如何離開 VIM。
- 如果是不小心進入，想離開 VIM 的：ESC 多按幾下，然後輸入 :q! ENTER 即可
下述摘錄自此篇：vi - How do I exit the Vim editor? - Stack Overflow
- :q to quit (short for :quit)
- :q! to quit without saving (short for :quit!)
- :wq to write and quit
- :wq! to write and quit even if file has only read permission (if file does not have write permission: force write)
- 😡 to write and quit (similar to :wq, but only write if there are changes)
- :exit to write and exit (same as :x)
- :qa to quit all (short for :quitall)
- :cq to quit without saving and make Vim return non-zero error (i.e. exit with error)
