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

Example script:

GREEN='\033[0;32m'
RED='\033[1;91m'
RESET='\033[0m'

branch_name="$(git branch --show-current)"
allowed_branch_name="my-branch"

if [ "$branch_name" != "$allowed_branch_name" ]; then
  echo "Current branch: ${RED}${branch_name}${RESET}"
  echo "Allowed branch: ${GREEN}${allowed_branch_name}${RESET}" 
  echo
  echo "You can't push directly to this branch."
  exit 1
fi

Insert the current branch into the top of the pre-push file

sed -i "" "s&An example&$(git branch --show-current)\n# An example&" .git/hooks/pre-push 

Replace "An example" with current branch \n # An example

Copy current branch to Mac clipboard

echo $(git branch --show-current) | pbcopy

:!echo $(git branch --show-current) | pbcopy
