# Query a property from the terminal, e.g. background color.

# XTerm Operating System Commands
# "ESC ] Ps;Pt ST"
oldstty=$(stty -g)
# What to query?
# 11: text background
Ps=${1:-11}
stty raw -echo min 0 time 0
# stty raw -echo min 0 time 1
printf " 33]$Ps;? 33\"
# xterm needs the sleep (or "time 1", but that is 1/10th second).
sleep 0.00000001
read -r answer
# echo $answer | cat -A
result=${answer#*;}
stty $oldstty
# Remove escape at the end.
echo $result | sed 's/[^rgb:0-9a-f/]+$//'
