Question

Is there a way to trigger a hook after a new branch has been checked out in Git?

Answer 1

Similar to others but verifies that the branch has been checked out once.

#!/bin/bash

# this is a file checkout – do nothing
if [ "$3" == "0" ]; then exit; fi

BRANCH_NAME=$(git symbolic-ref --short -q HEAD)
NUM_CHECKOUTS=`git reflog --date=local | grep -o ${BRANCH_NAME} | wc -l`

#if the refs of the previous and new heads are the same 
#AND the number of checkouts equals one, a new branch has been created
if [ "$1" == "$2"  ] && [ ${NUM_CHECKOUTS} -eq 1 ]; then
    git push origin ${BRANCH_NAME}
fi
