Toggle Redshift with Keyboard Shortcut
Redshift is a screen-tinting program that achieves similar goals to the popular f.lux1 program.
I perused through the redshift man-pages and noticed there is no
documented way to toggle redshift. Of course one can click the
notification area icon when using redshift-gtk or
redshift process, but neither is very user friendly. (The mouse is not
user friendly.) After some awkward DuckDuckGo-ing and Googling I found
an obvious solution on the redshift homepage2: simply send
the redshift or redshift-gtk process. When using redshift-gtk, one can
choose to send
SIGUSR1 to either redshift or redshift-gtk.
This is the script I came up with:
#!/bin/sh set -eu if ! pkill -x -SIGUSR1 redshift; then echo 'Could not find redshift process to toggle.' >&2 exit 1 fi
After installing the script into my system’s
PATH, now all I have to
do is add a line to my Xbindkeys3 configuration file (
~/.xbindkeysrc.scm) such as:
(xbindkey '(Mod4 F2) "toggle-redshift")
Now I can type
Mod4-F2 and toggle Redshift.
