WIP shell script to fix slightly off indentation of control statements (for mac)

gistfile1.txt

#!/usr/bin/env bash

# Cleans up almost k&r formated control statements to nicer ones, e.g.
#    if (something){ -> if (something)
#    while(something){ -> while (something) {
#
# Probably doesn't work on lots of things and has holes and will destroy your computer, use at your own risk.
# It worked for me on two files
#
# Usage:
# ./thenameofthisfile.sh MyInputFileThatIsSupposedToBeKR.c

sed -E -i -e 's/(if|while|else if|for) ?\((.*)\) ?{/\1 (\2) {/' $1
