Vi

Quick reference for basic editing in Vi
Vi is a very basic (yet incredibly powerful) text editor that comes with just about every single Linux Distribution. Using Vi allows you to avoid installing other text editors.

Basic Instructions:

Note: Avoid using the number pad in Vi.

Go into insert mode, here you may use arrows to navigate text, and edit it with the keyboard as normal: i

Exit insert mode: Esc (the escape key)

WHEN NOT in insert mode you may use:

Write changes: :w  (then enter)

Exit vi: :q  (then enter)

Exit vi without saving changes: :q! (then enter)

Example of usage...

[root@localhost ~]# vi /README.txt

i This is my first readme file, wrote with vi! (Esc key)
 * w
 * q

[root@localhost ~]# cat /README.txt This is my first readme file, wrote with vi!
