Git tips - lint + test pre-commit hook

A nice last minute sanity check I use is a pre-commit hook that auto runs test and lint commands from a makefile or package.json if they’re found:

 1#!/usr/bin/env bash
 2
 3if [ -f "$PWD/makefile" ] && [ ! -z "$(cat $PWD/makefile | grep '^lint:')" ]; then
 4    echo "running make lint"
 5    make lint
 6elif [ -f "$PWD/package.json" ] && [ ! -z "$(cat $PWD/package.json | grep "^\"lint\":")" ]; then
 7    echo "running npm run lint"
 8    npm run lint
 9fi
10
11if [ -f "$PWD/makefile" ] && [ ! -z "$(cat $PWD/makefile | grep '^test:')" ]; then
12    echo "running make test"
13    make test
14elif [ -f "$PWD/package.json" ] && [ ! -z "$(cat $PWD/package.json | grep "^\"test\":")" ]; then
15    echo "running npm run test"
16    npm run test
17fi

If the test or lint command fails then the git commit command fails. If I absolutely need to commit something in spite of the lint/test results I can do git commit --no-verify to skip the pre-commit hook.
