Gitgo or: How I learned to live with VCS

UPDATE: Only keeping thins post around as a reminder of how far I've come.

UPDATE: This is a bit outdated now, as I have added some features and polished up the code a bit. I will post the update after the migration to Ghost is done.

UPDATE: Changed order of main to try to avoid push conflicts
UPDATE: Multi-directory bug squashed! (I think)
UPDATE: Found a bug that breaks the script if you are deep in a multi-directory Git repo and call this script. (All of my repos are currently only one directory deep, so it might be a bit before I squash this bug...)

I didn't know what I was missing.

I have started using Git in my professional career, and I have to say I'm hooked. I'm just not overly fond of one aspect of Git. The commands.

Sure, after using it day in and day out it became less of a chore and more of a required familiarity, but I still wanted a better way so I decided to write a script in bash to help streamline my interactions with git.

I'll be the first to admit that this has (in one way or another) already been done, and probably better too, but I wanted to create my own. I'm sure I'll keep adding to it, polishing it, and making sure I've accounted for most (if not all) edge cases or errors, and of course all the while using Git to keep track of the changes and GitLab to have a more visually pleasing view into it all.
