Git hook to include the branch name on each commit

Tired to forget to write every goddam time the branch name on the commit messsage? This got you covered:

1. Add the prepare-commit-msg file to your .git/hooks/ folder;
2. Then, chmod +x prepare-commit-msg;
3. PROFIT!

prepare-commit-msg

#!/bin/bash

BRANCHNAME=$(git branch | grep '*' | sed 's/* //')

if [ -n "$BRANCHNAME" ]
then
   echo "" >> "$1"
   echo $BRANCHNAME >> "$1"
fi

Improved version

Requires git config commit.status = false. Also, works best with templates 😉

#!/bin/bash

GITDIFF=$(git diff --name-status -r)
