Why is my Git pre-commit hook not executable by default?

If you see the accepted answer in: Aggregating and uglifying JavaScript in a Git pre-commit hook, you'll see that I had to do a chmod +x on my pre-commit hook to get it to work.

Why is this not executable by Git by default?

Solution

  • Because files are not executable by default; they must be set to be executable.

    The sample files from a git init are all executable; if it's copied or renamed to a non-sample file, it will retain the original file's x flag.

    New files will be created with current defaults. In your case, view those defaults with umask:

    $ umask
0022

    By default, new files won't be u+x unless explicitly set to be.
