Hook scripting

Learn to write hook scripts.

What Are Hook Scripts?

Git hooks are scripts that run automatically when specific Git operations occur. Hook files are usually located in the `.git/hooks` directory and can be written as shell scripts. The script must be executable.

#!/bin/bash
echo "Hook executed"

Shell Scripts and Hook Files

A hook file can contain a script that the operating system can execute. When using Bash, the first line contains a shebang that identifies the interpreter. You can use `chmod +x` to grant execution permission.

chmod +x .git/hooks/example-hook
