crontab & mplayer static

linuxhippy · 11-13-2005, 06:42 AM

I put together a simple script that uses mplayer to play a radio stream. If I run this script using the keyboard it runs fine. If I put it into crontab, it plays along with a bunch of static. Any ideas why I get static?

Here's the script (radio):

clear
/usr/local/bin/mplayer -nortc -playlist /home/huntz/high.pls

Here's the crontab list:

30 7 * * * sh /home/huntz/radio

Here's high.pls:

[playlist]

perhaps mplayer need a shell with environnement variable?
crontab is very special, it launch applications or scripts with shell, without anything you see usually for a user.

I'm not sure how to do this-could you provide an example or a link?

when you launch in crontab, try type
30 7 * * * /bin/sh /home/huntz/radio
because crontab don't know where is the interpreter.
In radio script, you can include an execution of the user's profile, who have the rigth to eXecute the script. Try in header of the script :
. /home/huntz/.bash_profile (don't forget the "." at the first caracter of the line)
or, try :
30 7 * * * su - huntz "-c /bin/sh /home/huntz/radio" (with double cotes)
