Tip: vi and lowercase/uppercase

Submitted by lefred on Thu, 01/10/2008 - 13:32

As always I use my blog as reminder of some useful commands or tips.

This one is for dimi, to change the case of a full document in vi, use the following command to transform everything in lowercase :

<ESC>:%s/.*/\L&/

and in uppercase :
<ESC>:%s/.*/\U&/

I hope this helps ;)

for uppercase: gggUG
for lowercase: ggguG

PS: the first 2 g's are for moving to the beginning of the document.
PS2: works in vim, don't know about plain vi

so just wanted to break down that last post so people know what's up with it.

the first 2 'g's put your cursor to the beginning of the file. the 3rd g puts you in what appears to be a "replace" mode of some kind. U means uppercase (or u means lowercase) the final G means until the end of the file.

So if you want to manipulate just a single word you should move the cursor to the beginning of the word then type gUw ((g)replace to (U)uppercase until (w)the end of the word).

Or if you want to go from the current position to the end of the line gU$ ((g)replace to (U)uppercase until ($)the end of the line).

Or if you want to go from the current position to the next 'x' on the line gUtx ((g) replace to (U) uppercase (t) to (x) the x character)... Of course you can replace x with any character you want.

Figured that might help those who don't know about jumping around in a file.

(also if you only want to do the current line and the next two lines: gU2).

This stuff is handy!
