git hooks

To activate pre-push, rename .git/hooks/pre-push.sample to .git/hooks/pre-push

Example script:

branch_name=$(git symbolic-ref HEAD 2>/dev/null)
echo "$branch_name"
if [ "$branch_name" != "refs/heads/min-branch" ]; then
echo "You can't push this branch." # also prevents git push --force-with-lease
exit 1
fi
exit 0

should work given that this command:

git symbolic-ref HEAD 2>/dev/null

gives: refs/heads/min-branch

and:

git symbolic-ref HEAD 2>/dev/null | cut -d"/" -f 3

gives min-branch

Bash. check if a file exists

Check if prepush is activated or not

lsprepush() {
  if [[ -f ".git/hooks/pre-push" ]]; then
    echo ".git/hooks/pre-push was found:"
    echo "pre-push is activated"
  else
    if [[ -f ".git/hooks/pre-push.sample" ]]; then
      echo ".git/hooks/pre-push was not found:"
      echo "but .git/hooks/pre-push.sample was found:"
      echo "pre-push is deactivated"
    else
      echo "Hmmmmm"
    fi
  fi
}
