in VIM sometimes when saving, I accidentally hit capital W instead of its lowercase brother. I am prompted for my system password, so I assume it is running a sudo command of some sort, but do you know what?
Thank you!

As others have said, :W
isn't defined in vanilla vim (7.0 here), so it sounds like some plugin you've installed has added it.
:command W
will tell you what it does.

I guess you have a common mapping for :W
in your .vimrc
to save the file as typing :w
does. Often people press too long the shift key for the colon and make the typo but actually wanting to type :w
. You've possibly got this mapping by copy and paste of snippets into your vimrc or by using a pre-configured vim setup such as spf13-vim distribution.
.vimrc:
command! W write
However, as pointed out by Sam Stokes checking the meaning of commands via
:command W
and for keycombos:
:verbose map < C-j>
is a general approach to find out what a command or keycombo does.

You can test this line
{Cursor}It's the test
{Cursor} : Cursor position in normal mode, w: will move word which separated by " ,./?" W: will move word which separated by " " only

That's strange. The normal mapping of "W" advances by a WORD, where WORD is defined by a sequence of non-blank characters.

@akira that makes more sense. – bentsai – 2010-05-26T16:00:47.393

:W
doesn't do anything in my copy of VIM (6.4), for what that's worth. What does :help :W
tell you? (For me, it just takes me to the help for :w
, which wouldn't be, um, help-ful for you. :-) )
1in my vim it gives me "E492: Not an editor command: W" if i try to ":W". – akira – 2010-05-26T16:10:02.783
Ahh..
thank you. I got the vimrc from a friend and it was:
w !sudo tee % > /dev/null – tesmar – 2017-03-01T19:50:30.413
