#shell scripting

now playing with playerctl: loops through chromium (qutebrowser), mpv, and mpd to find what's playing, latter two need mpv-mpris (in most package repos) and mpd-mpris (a go program)

...output from a python program i wrote dw

#!/bin/sh [ "$(date +%H)" -gt "11" ] && GREET="afternoon" || GREET="morning" notify-send "Welcome." "Good $GREET, $USER"

That first line is doing a few things. First, it is getting the current hour (in 24-hour time, so an integer between 0 and 23) with $(date +%H). Then the -gt checks if it is greater than 11 (NOT 12; our hour value starts at 0) . If the hour is greater than 11, it sets the variable GREET to "afternoon". If the hour is NOT greater than 11, it sets GREET to "morning".

The second line is a call to the notify-send command, a simple command-line program to send desktop notifications. We pass 2 arguments: The notification title (or "summary" as it is referred to in the documentation), and the body. Our title is simply "Welcome." In the body, we call 2 variables: the GREET variable we set in the first line, and the USER variable which stores your username.
