Used to clean up rubyish code, make unix line endings, tabs to spaces, kill trailing whitespace.

code_cleanup.sh

#!/bin/bash

main() {
  find_files |
  exclude_vcs_dirs |
  exclude_common_dirs_that_are_not_ours |
  exclude_extra_dirs |
  cleanup_the_code
}

find_files() {
  find -E . -iregex '.*(rb|html|erb|rhtml|rjs|plain|rxml|yml|rake|eml|css|scss|sass|haml|js)$'
}

exclude_vcs_dirs() {
  grep -v -e '.git/' -e '.svn/'
}

exclude_lock_files() {
  grep -v '.lock'
}

exclude_common_dirs_that_are_not_ours() {
  grep -v -e 'vendor/' -e 'tmp/' -e 'public/' -e 'images/' -e 'img/'
}

exclude_extra_dirs() {
  grep -v -e 'vendor_archive/' 
}

cleanup_the_code() {
  xargs -I{} sed -i '' -E -e "s/[[:space:]]*$//" -e "s/`printf '\t'`/  /g" -e "s/\r\n$/\n/" {} 
}

main

I threw it in scripts/ and then did chmod +x scripts/code_cleanup.sh and finally ./scripts/code_cleanup.sh

It is destructive, there are no backups (hopefully you're using git), but it should work as advertised.

Inspired by lots of code and stackoverflow and helped along with man pages, including:
