Fetch utility. "sing" and the code for color printing are from https://github.com/Manas140/sh, and wmctrl is needed for detecting the window manager.

singfetch.sh

echo -e "$c5$e1 $c6- $(sing $distro)"
echo -e "$c5$e2 $c6- $(sing $kernel)"
echo -e "$c5$e3 $c6- $(sing $init)"
echo -e "$c5$e4 $c6- $(sing $SHELL)"
echo -e "$c5$e5 $c6- $(sing $windowmanager)"

printf "\n$c1▇▇$c2▇▇$c3▇▇$c4▇▇$c5▇▇$c6▇▇$c7▇▇$c8▇▇$end\n\n" 

yeah i was gonna work on that
