All options must set before [File].

Multiple files

Currently can only update single file, but we can use find and xargs to treat multiple files:

Copy pre-commit.sample.sh as .git/hooks/pre-commit, chmod +x.

This hook will not touch un-staged file, even this file have staged part.

Notice for usage in MacOS X

MacOS X uses BSD version command utils, so you need GNU versons:

• Bash v4
• grep
• sed
• xargs

You can install them via brew and configure to use them, here is some useful links:

Brew by default install grep, sed, xargs with prefixed with g, like ggrep, to overwrite system grep:

• In /usr/local/bin/, ln ggrep to grep, so do gsed and xargs
• Config PATH, put /usr/local/bin/ before /usr/bin/ or $PATH
• Restart bash
