git - Prevent commits in a local branch

Question

In my local git tree I pull commits from the "master" branch in the repository, but all development is done in a different branch, and pushed in a different branch too.

I would like to avoid mistakes and prevent accidental commits in my local "master" branch, and allow only pull requests (then I'd rebase the developement branch to the updated master). Is this possible? How?

You can use a pre-commit hook.

For example, place the following script as .git/hooks/pre-commit:

#!/bin/bash
if test $(git rev-parse --abbrev-ref HEAD) = "master" ; then 
  echo "Cannot commit on master"
  exit 1
fi

And set it as executable

chmod +x .git/hooks/pre-commit
