Scripts I wrote that I use all the time

It's weird how the circle of life progresses for a developer or whatever.

- When I was a fresh engineer I used a pretty vanilla shell environment

- When I got a year or two of experience, I wrote tons of scripts and bash aliases and had a 1k+ line .bashrc the same as OP

- Now, as a more tenured engineer (15 years of experience), I basically just want a vanilla shell with zero distractions, aliases or scripts and use native UNIX implementations. If it's more complicated than that, I'll code it in Python or Go.

When I had one nix computer, I wanted to customize it heavily.

Now I have many nix computers and I want them consistent and with only the most necessary packages installed.

Besides many nix computers I also have wife, dog, children, chores, shopping to be done. Unlike when I was young engineer I could stay all night fiddling with bash scripts and environments.

What does your wife, dog, children, chores, and shopping have to do with custom configuration and scripts? Just set up a Git repo online, put your files there, and take a couple of minutes to improve it incrementally when you encounter inconveniences. And just like that, you made your life easier for a marginal effort.
