If you make the following script (testusr.fish):
---------------------------------------------------------
function testusr --on-event USR1
echo Got the signal
end
while true
sleep 1
end
---------------------------------------------------------
then run it as
command fish testusr.fish &
kill -USR1 %1
do you see anything?
regards,
Maxim
