script to take screenshot every hour

Hello, can anyone help me ? I have a (working) Bash Shell Script to take a snapshot of an ONVIF camera. When i launch te script
at the command prompt in using "bash script.sh" it works perfect and saves the picture in the specified directory as photo.jpg with
as owner "pi" and rights "rwxr-xr-x" what is perfect for me !
To run the script every hour in Domoticz i call the script.sh using a Blocky script or dzVents script (i tried both). This also works, but
the wile is saved in de specified directory with other rights and owner !! Owner is "root" and permissions "rw-r-----". So i can't copy them,
can't change te permissions etc....
Anybody knows what the reason for this is or how i can solve this ?

Hi
I guess that the user used by domoticz to run is root. You can change the rights at the end of your scripts and the owner too with chmod and chown.
Btw, is it possible to share your script i'm interested by this idea.
Thanks

This is the code i use in the bash script :
Code: Select all
#!/bin/sh
export DATETIME=`date +%Y%m%d%H%M%S`
ffmpeg -loglevel fatal -i rtsp://192.168.1.19:554/user=admin_password=tlJwpbo6_channel=1_stream=0.sdp?real_stream -vframes 1 -r 1 /home/pi/Pictures/$DATETIME.jpg
Can you help me how i can change the owner and permissions ? What do i have to add ? I'm a "newbie"

For me you have to add these 2 lines. 1st allow you to change the owner of the file and 2nd change the auth on the file.
Code: Select all
chown user:group your_file
chmod 755 your_file
