Vim – How to Save Edited Files

vim

I can't save changes after editing 

sudo vi /etc/network/interfaces

Text before editing: 

auto lo
iface lo inet ...

Edited to:

auto eth0
iface eth0 inet dhcp

What key combination or sequence must I press to save this?

Best Answer

You're probably in editing/insert mode. You need to type the following sequence :

  1. Esc, to quit edit mode and fallback to command mode ;
  2. :+w+q, start with a : (colon) then press w and finally q to write and quit (or just :w to write without quitting)
  3. then press Enter to valid.
