One liner to extract IP-address from lxi tool output:
lxi discover | grep 'DS1104Z' | grep -oE '192\.[0-9]+\.[0-9]+\.[0-9]+' 192.168.120.56
Take screenshot from oscilloscope in IP addres SKOOPPI:
# SKOOPPI=$(lxi discover | grep 'DS1104Z' | grep -oE '192\.[0-9]+\.[0-9]+\.[0-9]+')
echo Screenshot for SKOOPPI=$SKOOPPI
lxi screenshot -a $SKOOPPI pics/lxi-output.pngSceenshot taken:
Set environment variable SKOOPPI to the IP-address of the
oscilloscope.
export SKOOPPI=192.168.120.56
Ping IP-address SKOOPPI
ping -c 2 $SKOOPPITake a screenshot using netcat using the idea presented in

Options passed to netcat:
-N: ‘shutdown(2) the network socket after EOF on the input.’.-w: idle timeout
