Oh Shit, Vim or Vi

vi is the de facto standard Unix editor, you find it in every NIX derived OS.

Thats why you should learn a handfull of commands, you can the show off your Vi skills

The first thing you need to learn is how to exit

1. just quit: :q
2. just quit and not save: :q! or ZQ (shift-Z-Q)
3. quit and save any changes: ZZ (shift-Z-Z)

Next up is editing

1. insert: i then escape to exit insert mode
2. append: a then escape to exit insert mode then escape to exit insert mode
3. append at the end of the line: A (shift-A)
4. Begin a new line below the cursor: o then escape to exit insert mode
5. Begin a new line above the cursor: O (shift-O) then escape to exit insert mode

Now you can exit and edit a file, what if you want to delete stuff?

1. Delete characters: x
2. Delete lines: dd
3. Delete the characters under the cursor until the end of the line: D (shift-D)

Great, you can exit and edit and even delete. SO what else would bew cool to do?

How about copy a line and past it else where?

1. yank a line: yy
2. move to destination line
3. paste after cursor p or P to paste before the cursor

SO you made a change and you need to undo it, or you made a change and want to repeat it. We have you covered!

1. undo is just u
2. you can redo a change with CTRL-R
3. repeat the last change with .

Thats most of the cool stuff I know, the last 2 things are searching

1. searching can be started with / then type out what your looking for.
2. repeat your search with n
3. you can also search up the file with ?

And the very last thing is substituting, this is find and replace

1. :s%/find/replace/g this is look for find and replace it with replace everywhere
2. :%s!file path!new path!g you can use any delimiter, that helps with changing a path
