How to use?
.git/hooks/pre-commit
in your project .git folderchmod +x .git/hooks/pre-commit
to make it executableIf you want to skip the hook just add the
--no-verify
flag:git commit --no-verify
If you want to customize for files, keywords, just modify these contants to meet your need:
Bonus: (thanks to wacko/pre-commit)
$HOME/.git-templates/hooks
$HOME/.gitconfig
:So it will be automatically copied into your project any time you run git init
(you can replace
.git-templates
with any other path)Screen shots:
