The following are POSIX compliant shell scripts that I have mainly written for personal use. I've decided to share them in case anyone is interested or needs a point of reference to create something similar. In most cases they're designed to be mapped to keyboard shortcuts. Most of these were written while teaching myself shell scripting. I am by no means an expert. If you see a glaringly obvious issue that could be improved upon, please let me know.
OpenBSD versions below are likely newer and more complete. Since I no longer use linux much on the desktop, those versions will not be updated anymore.
