This is my personal collection of scripts.
They range in complexity and usefulness; some of them are little more than aliases, while others contain a lot more logic and functionality. They should all support a -h or --help argument to display a summary and basic help information (it should be considered a bug if any don’t). Some of the scripts have configuration options at the top of the file that you may need or want to change, but I strive for “sensible defaults” and attempt to auto-detect “the right thing” when possible.
Even though I wrote them primarily for myself, all of these scripts should still be usable (and hopefully useful) to others. I have made an effort to write clean code (with comments where warranted), to handle possible error conditions, and to give helpful output when they occur.
The scripts are mostly written in Fish (because Fish is great), but a few of them are written in other languages (because other languages are also great, and fun to play with). As long as you have the script’s requirements, it should work just as well for you. Please don’t hesitate to open an issue if you find any problems with them.
The scripts in this collection that I find most useful are marked with ⚡.
The full list of scripts follows. Each is listed with its requirements and a short description.
