Hooks

Hooks are local to a git repo they are not copied over to the new repository when you run git clone
In shared dev team, typically hooks are stored in the project directory itself in a seperate hooks directory, which is version controlled.
A new dev needs to either symlink or copy hooks to local .git/hooks

Sample hook files are by default generated by git in a git repo in the directory .git/hooks . The .sample suffix of the filenames prevent them from executing

Hooks are simple executable scripts, by default sh, but can be written in any scripting language using #!/usr/bin/env <executable>

Client Side (local) Hooks

• pre-commit
• prepare-commit-msg
• commit-msg
• post-commit
• post-checkout
• pre-rebase

Server Side Hooks

• pre-receive: called once before receiving the pushed changes
• update : called every time before a ref is updated i.e. before every commit being added to remote repo
• post-receive: called once after the push for all refs is completed
