Answer 1

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
        done
done || exit $?

Answer 2

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.

#!/bin/bash
import os
echo "Running pre-commit hook" 
checks=os.environ["APPSETTING_DEVPASSWORD"],os.environ["APPSETTING_DEVUSER"],os.environ["APPSETTING_DEVPASS_ELMAH"]


git diff --cached --name-status | while read x file; do

          if [ "$x" == 'D' ]; then continue; fi
        for word in $checks
        do
            if egrep $word $file ; then
                echo "ERROR: Disallowed expression \"${word}\" in file: ${file}"
                exit 1
            fi
        done
done || exit $?
