Git pre-commit hook to check for a string and exit code 1 if the string exists

I am trying to get a pre-commit hook to work, to check the stagged files and read the difference to check for a few strings. If the strings exist, commit has to fail. 

#!/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 $?

It still commits the files even though the strings exist in the files. Any guidance would be greatly appreciated. I am fairly new to bash.

It must be something like this:

#!/bin/bash

echo "Running pre-commit hook" 
checks=($APPSETTING_DEVPASSWORD $APPSETTING_DEVUSER $APPSETTING_DEVPASS_ELMAH) # create an array

git diff --cached --name-status | while read flag file; do
    if [ "$flag" == 'D' ]; then continue; fi

    for word in ${checks[@]}
    do
        if egrep -q "$word" "$file"; then
            echo "ERROR: Disallowed expression \"${word}\" in file: ${file}" >&2
            exit 1
        fi
    done
done
