Execute git pre-commit hook only if files in certain directory modified

bashgit

I am trying to create a bash script for a git pre-commit hook. Whenever a commit is made, I want to check if files in a certain directory are part of the staged files and if so, run a command (Grunt task). So far I have everything working, except for only running if certain files are modified. I'm trying to get this to work:

SRC_PATTERN="site/assets/js/"
if [ grep --quiet $SRC_PATTERN `git diff --cached --name-only` ]
then
  echo "none"
  exit 0
fi

This is unfortunately giving me errors.

try,

git diff --cached --name-only | if grep --quiet "$SRC_PATTERN"
then
    ...

Happy hacking

Linux – How to execute commands as root in git post-receive hook

You need to separate the commands in your sudoers file using commas. Right now, you're authorizing a single command: /sbin/start myapp-service /sbin/stop myapp-service.

You need to write admin ALL=(ALL:ALL) NOPASSWD: /sbin/start myapp-service, /sbin/stop myapp-service.

How to commit files modified by pre-commit hook in Git

You can do something like this:

#!/bin/sh
#

perl -i -pe 's/var app_version = "\d+\.\d+\.\K(\d+)/ $1+1 /e' ./version.js

git add ./version.js

What it does: It changes the string var app_version = "0.1.1"; to var app_version = "0.1.2"; and adds the file back to the git commit process. When you commit the latest change will be included.
