#=< TLDR: Where's the code for git's internal command line parser?

I'm interested in the internals of git, more specifically it's command
line parser.

One place to start is https://github.com/git/git/blob/master/git.c

Wait, is all of Git just one big executable or are there many
executables and `git` is just the front-end for accessing the
separate git executables, such as say, the one for processing
commits?

Yes, `git` is a front end.

If you are on Windows, it gets even more interesting because all the
individual sub-commands are just hard links back to the single git.exe
that then links to those sub-command's code.

I'm on Ubuntu 20.04, just in case you ever want to know.

And I likely will consider this "front-end to many separate
executable apps" approach for my future large projects.

Thanks for your help! I've also cloned the git repository of
git, and I'll take a look through the source code.

I'm also a beginner to C, not quite an expert at it.

Does Git use a library like getopt for it's command line handling, or
does it use a custom parser?

If possible, I would appreciate being redirected to the source code
files that handle this.
