Here's some of my bash scripts I use.
andy.sh - pings an address and gives a thumbs up/thumbs down based on the result. I use this to see what network my kid's computer is on.
background.sh - changes my i3 background.
bar.sh and temp.sh - are used with a weather station and weather display console's clientraw files to pull the current temp/baro and give an arrow indicating the trend.
gpu.sh - sets my video card power limit to max.
ipcam.sh - just moves some files on a server.
logs.sh - cleans up logs directory. Useful on low memory machines.
music.sh - randomly picks a line of text from a file, good for piping into a music player.
pingtest.sh - pings and address and returns the response in a nice clean format for status bars.
vm_windows - is just a script to open a vm.
weather - a weather script for polybar.
