Using vi and forgetting the bastarding sudo command.

OK, so how many of you have been messing about with a system file using vi and you’ve edited about 10 lines. You go to save the file and it complains that it’s Read-Only!! Gah, you then do your thing to correct it and slap yourself for making THAT mistake AGAIN.

Anyway, rant over. Fix it by doing this!

vi ~/.vimrc

Insert this

command! -bar -nargs=0 Sw :w !sudo tee % >/dev/null

Now when you go to save and it complains just type :Sw and it will save it out as root and then ask you to reload (If someone know how to do this part automatically it would be appreciated )

Problem solved!
