Thanks. Good cleanup overall. Just a few things to put back as I'd like them.

Thanks for the follow up. Looks like the commit with the changes hasn't been pushed yet...or maybe Github is being laggy.

...or maybe I'm looking too soon 😀

@itzg No problem! I just pushed everything.

Just a couple tiny tweaks left. Thanks!

[keepittechie]

No problem! It should be corrected now.

Thanks for merging the pull request! Appreciate the feedback and guidance on keeping the scripts readable and consistent. Happy to have contributed and looking forward to working on more improvements in the future if needed. By the way, I have a repository on my profile called "mcsli" where I'm scripting the full installation of Minecraft on Linux. I found your project while searching to make sure I wasn't duplicating something already on GitHub and to learn more about shell scripting. Feel free to check it out if you're interested! Peace!

You're welcome and glad to see a fellow Minecraft automation project!
