This program sets a random background color on the X window server.

This is useful if you use dwm, for example. The script selects one of

the 16'777'216 colors from #000000 to #ffffff and prints it to stdout

so that you can save it if you like it.

random_digit() {

local digits digit

digits="0 1 2 3 4 5 6 7 8 9 a b c d e f"

for digit in $digits

do printf '%s\n' "$digit"

done | shuf -n1

}

color='#'

for i in $(seq 6)

do color="$color$(random_digit)"

done

printf '%s\n' "$color"

xsetroot -solid "$color"
