Remove Trailing Whitespace With Vim
Posted by Weston Ganger
Vim is awesome and it can remove all trailing whitespace automatically.
For the Current File:
If you want to get Vim to remove all trailing whitespace whenever you save the file you can add an auto command to your ~/.vimrc
# on every file save autocmd BufWritePre * :%s/\s\+$//e # on certain file extension autocmd BufWritePre *.rb :%s/\s\+$//e # on certain file types autocmd FileType ruby,php,java autocmd BufWritePre <buffer> :%s/\s\+$//e
