How to clear code base, trailing spaces, newlines, etc.

I have a code base that makes me run into conflicts due to lagging spaces. I would like to clean it.

I want to:

  • Delete all trailing spaces
  • Delete newlines at the end of files
  • Convert all strings to unix (dos2unix)

  • Convert all leading spaces to tabs i.e. 4 spaces to tabs.

  • When ignoring the .git directory.

I am on OSX Snow Leopard and zsh .

so far I:

sed -i "" 's/[ \t]*$//' **/*(.)

which works fine, but sed adds a new line at the end of every file it touches, which is not good. I don’t think sed can be stopped from doing this, so how can I delete these new lines? Maybe there is some kind of awk magic here.

(Full answers are also welcome)
