[vim] Clear trailing whitespace in file

:%s/\s\+$//
% acts on every line in the file. \s matches spaces. \+ matches one or more occurrences of what's right behind it. Character '$' matches end-of-line.

What Others Think

It's worth making one slight change: add the search flag 'e' to the end (no error message). See "help :s_flags" for more details. :%s/\s\+$//e Then you can do crazy things (in your .vimrc) like: autocmd BufWritePre *.c %s/\s\+$//e Before saving my source code, strip any trailing space!
