Git pre-commit hook to find text in files

Answer to mark this question as having an answer:

OP ended up with:

disallowed="word1 word2"git diff --cached --name-status | while read x file; do        if [ "$x" == 'D' ]; then continue; fi        for word in $disallowed        do            if egrep $word $file ; then                echo "ERROR: Disallowed expression \"${word}\" in file: ${file}"                exit 1            fi        donedone || exit $?

I am using the same logic as above and even though the stagged file contains the disallowed word, it commits the changes to the branch. Any lead would be greatly appreciated.
