Apparently it's not ok. I'm running this under pCP6-b9. I changed my
script to look like this, so that that line is line 16:
Code:
--------------------
#!/bin/sh
# start pigpiod daemon
pigpiod -t 0 -f -l -s 10
# wait for pigpiod to initialize - indicated by 'pigs t' exit code of zero
#while ! pigs t >/dev/null 2>&1 ; do
# printf "\nWaiting for pigpiod to initialize\n"
# sleep 1
#done
#printf "\npigpiod is running\n"
count=10 # approx time limit in seconds
while ! pigs t >/dev/null 2>&1 ; do
if (( count-- <= 0 )) ; then
printf "\npigpiod failed to initialize within time limit\n"
exit 1 # or however you want to deal with failure
fi
# printf "\nWaiting for pigpiod to initialize\n"
sleep 1
done
printf "\npigpiod is running\n"
.
.
.
--------------------
It gives these errors:
Code:
--------------------
./sbpd-script.sh: line 16: can't open =: no such file
./sbpd-script.sh: line 16: count--: not found
