Convert whitespace from tabs to 2 spaces

whitespace.sh

#!/bin/bash

set -e # fail on nonzero status

cd $1

files=`find . \
        -not \( -path ./vendor -prune \) \
        -not \( -path ./tmp -prune \) \
        -name '*.html' -o -name '*.js' -o -name '*.coffee' -o \
        -name '*.sass' -o -name '*.scss' -o -name '*.erb' \
        -type f`

# Handle whitespace in filenames
#   http://en.wikipedia.org/wiki/Internal_field_separator
IFS=$'\n'

for file in $files; do
  echo -n "Converting '$file' ... "

  expand -t2 "$file" > out.tmp
  mv out.tmp "$file"

  echo 'done.'
done

rm out.tmp at the end perhaps?

mv will remove it

Worth adding -not \( -path ./node_modules -prune \) \

☝️ what he said.

got it -- rm -rf ./node_modules
