Help with bash script!

[el_heffe80]

I am trying to capture a picture from a wireless webcam at a specific interval (starting at 0600, every two hours until 2000). So I found this command that will capture an image when run from the command line (this is a headless server). Thing is, it throws up a bunch of stuff on the screen, like the image is being generated from letters and numbers in colors.
Anyways, when I put it in a script (pasted below) and run it same thing. Image is created, and renamed. When I run this same script through cron it fails. As a regular user it produces no errors, as root it fails because VLC doesn't like root. Anyways- is there a fix to this script? Thank you in advance.

#!/bin/bash vlc -I dummy http://login:password@192.168.44.19/snapshot.cgi --video-filter scene --no-audio --scene-path /path/to/TimeLapse/Tree/ --scene-prefix image_prefix --scene-format png vlc://quit --run-time=1 --quiet DATE=$(date +"%F_%H%M") mv /path/to/TimeLapse/Tree/image_prefix00001.png /path/to/TimeLapse/Tree/$DATE.png

When it is run from the command line this is the output:

Anyways, whatever else you need, let me know. I have very little clue what I am doing, if it isn't already obvious.

Can you try prefixing your command with sudo -u <yourusername> ? That should run it as a normal user.
