Compare the amount of opening and closing braces in a file. This can be used as trivial check for Puppet scripts before Puppetlint is used. It might show false positive in case curly braces are embedded in strings.

#!/bin/bash

FILE=$1

function remove_comments {
	sed -e 's/#.*$//' 
}


OPEN_BRACES=$(cat $FILE | remove_comments | fgrep -o \{ | wc -l)
CLOSE_BRACES=$(cat $FILE | remove_comments | fgrep -o \} | wc -l)

if [ "$OPEN_BRACES" -nq "$CLOSE_BRACES" ]; then
	>&2 echo "$FILE has mismatching brace counts.(open: $OPEN_BRACES, close: $CLOSE_BRACES)"
	exit 1;
