# POSIX_Scripts
A set of POSIX* shell scripts designed for personal use. No guarantees when it comes to quality, as these are also used for various minor experiments of mine.
A set of POSIX* shell scripts designed for personal use. No guarantees when it comes to quality, as these are also used for various minor experiments of mine.
Links - wrapper script for managing links2 and tabbed
fpm - wrapper for using ffplay to manage music
fpv - the above, but video
gasutc - "Get and Set UTC" over HTTPS using ncat
gcl - one-liner to g(it)cl(one)
iview - simple wrapper for sxiv; auto-sizes based on image dimensions
ls - one-liner to pipe ls through cols
man - short script to auto-resize mandoc output
modem-manager - used to manage laptop PCIe WAN modems. rather dense
netsh - an old experiment that serves as a simple TUI for managing network interfaces... and an example of how not to use AWK
plumber - one of my more sophisticated scripts; plumber creates pipes between programs based on what sort of input it receives, and handles errors (somewhat) intelligently
