Some shell scripts I've written, all licensed GPLv3 unless otherwise stated.

What each script does:

fans	fans <rpm of first fan> [rpm of second fan, if omitted first arg is applied to both fans]	E.g. fans 2000, fans 1000 1500
Changes the speed of the fans on my Corsair H110i GT via printf'ing directly into its /dev/hidraw device. I believe with some adjustments it should work on other Corsair Hydro series liquid cooling systems, but no guarantees.
img	img <image files...>	E.g. img photo001.jpg photo002.jpg
Displays images in the terminal in 24bit colour and using half-height block characters ▄. Uses imagemagick so supports anything that does.
s	Log: log [journalctl args] Trailing service log: log [service name] Following commands can be prepended with u for user services: Service status: s <service name> Start service: start <service name> Stop service: stop <service name> Restart service: restart <service name> Start inactive or stop active service: toggle <service name> Enable starting service at boot: stay <service name> Disable starting service at boot: leave <service name> Reload systemd unit files: reload Reload service's config: reload <service name>	E.g. s, restart sshd, toggle transmission, us sunshine, ustart sunshine
The Simple Short Service Script is an easier to type alternative to systemd's verbose systemctl for controlling services. Place s in your bin folder and create these symbolic links to it for i in log {u,}{start,stop,restart,toggle,stay,leave,reload}; do sudo ln -s /usr/local/bin/{s,$i}; done.
