Git Version Control Cookbook - Second Edition

How to do it...

What we want to do in the first example is to check whether or not the defect information is correct. There is no need to release a commit that refers to a defect that does not exist:

1. We will start by testing the commit-msg hook. First, make a copy of the current hook, then we will force the hook to exit with a non-zero value that will abort the creation of the commit:

$ cp .git/hooks/commit-msg.sample .git/hooks/commit-msg

2. Now, open the file in your preferred editor and add the following lines to the file:

#!/bin/bash
echo "you are not allowed to commit"
exit 1

3. Now, we will try to make a commit and see what happens, as follows:

$ echo "Frogs, scallops, and coco shell" >> fishtank.txt
$ git add fishtank.txt
$ git commit ...
