Save a file you edited in vim without the needed permissions

this is just awesome! of course you have to have sudo rights...

awe-some !

Unfortunately this does not work well in gvim.

I wish I could vote this up more than once. Thanks!

nice - thanks!

I use

which is similar, but shorter (you can add sudo in there if you want).

awesome!

I always quit vi and sudo vi when I find I haven't write permission before. This command save me much time.

!sudo cat > % won't work:

* the su-ed command is "cat" but

* > % isn't an argument for "cat", but a redirection

it's the same for sudo echo > myRootFile.txt

you could try with sudo sh -c "cat > %" but it's longer

so tee is ok.

comments welcome.

greatest commend ever!!! tnx!

how often did i miss this command, perfect!

+1 vote for greatest command ever

i have added:

cmap w!! %!sudo tee > /dev/null %

to my .vimrc, so I can just use :w!! to write files with sudo

Pretty sweet. I'm an Emacs guy, but I'm impressed with the succinct way vi handles changing effective UID.

By the way, does this work for files that have spaces in the filenames? I would guess that it wouldn't. Is it fixable by double-quoting the %?

You made me curious about filenames with spaces so I had to try it out. It only works with the "%". But as a general rule, I try not to name Unix files with spaces.

Really nice! I just freaked out when I tried this with nvi (in Ubuntu 9.10)... it did not ask for my password and yet it wrote an /etc file. Please shed some light!

Wow, this will come in handy. So will f3lix's :w!!

but I like to use abbreviations, i think they are cleaner than remapping:

Thanks for this. It will save me a lot of frustration.

is this also possible for nano?

Cool.!

Make sure to configure sudo properly to ask you for your ROOT password and not your USER password.

Otherwise it reduces the security of your system.

:w !sudo tee %

I'm hoping someone can elaborate on this command for me.

Not sure I understand what the "%" is doing, and where tee is getting its input from. Tee reads from standard input and outputs to the first argument (file), which in this case, is the "%". In VIM, the "%" is often used with regular expressions to mean "every line in the file".

So how is this working? Because using those definitions, the command doesn't make any sense.

...I should add, great command. This situation happens to me all of the time.

Have my babies? Just kidding. Awesome solution for a common derp.

I can not tell you how often i use this.

@yohhan % in vim command line mode ， It represents current file, you can test it with :!echo % in vim

@yohhan or :h cmdline-special
