Hello devs
First, thanks for an awesome solution, the quality from me getting going to
today has been amazing!
I have a question (and assume it is a beginners mistake). I have setup a
call from *track_generic_move* to* motionTrackMove.sh *that is not being
run, however if I call it from the command line (either as user *pi* or via
*sudo*) it works perfectly...
I can see this is being called in the motion.log file (below)
I have tried calling this as:
/home/pi/mlai/motionTrackMove.sh
/usr/bin/sh /home/pi/mlai/motionTrackMove.sh
The bash script motionTrackMove.sh has been set to execute (see below).
Any ideas please?
*tail -f /var/log/motion/motion.log*
[1:ml1] [DBG] [EVT] [Feb 17 00:54:24] generic_move: Executing external
command '/home/pi/mlai/motionTrackMove.sh'

#file: motionTrackMove.sh
echo 'Called motionTrackMove.sh' >> /home/pi/mlai/log
ls -la motionTrackMove.sh

OK, must be something to do with the shell? As this works every time,
please consider this request closed by me as using Python is fine.
*track_generic_move* /usr/bin/python3 /home/pi/mlai/movementDetected.py
'[track_generic_move] ***x/y/z etc***'

I'm not sure about your system, but I don't think /usr/bin/sh usually
exists, it should be /bin/sh, but since your shell is written in bash,
then it should probably have been /bin/bash.
In any case, seems you have a working solution now. It might be good if
motion logged an error message if the executable doesn't exist, or log
the return code or something, this might have provided a better clue to
the problem.
PPS, maybe the above is wrong, on my pi:
root@pi-03:~# which sh
/usr/bin/sh
root@pi-03:~# ls -l /usr/bin/sh
lrwxrwxrwx 1 root root 4 Oct 22 14:01 /usr/bin/sh -> dash
root@pi-03:~# ls -l /usr/bin/dash
-rwxr-xr-x 1 root root 129536 Mar 30? 2020 /usr/bin/dash
root@pi-03:~# ls -l /bin/sh
lrwxrwxrwx 1 root root 4 Oct 22 14:01 /bin/sh -> dash
root@pi-03:~# ls -ld /bin
lrwxrwxrwx 1 root root 7 Oct 22 14:00 /bin -> usr/bin
So, maybe it was a problem with using dash instead of bash... though
again, you could re-configure the system such that sh points to bash...
so overall, maybe motion needs better logging.
To work it out, you could use strace to better see what motion is
calling and why it fails (the syscall and results).
Regards,
Adam
