Hi

If I run the shell script below I get an mp3 file of the radio broadcast I 
want. Works great run as root or as me and the files always end up the 
directory I've hard coded for them.  I want to run it from a cron job but 
it's not happening, can anyone tell me how to get it to work?

Using cron:-
Run as me I don't think I get any output at all.  (least not a Show.wav or 
an audiodump.wav)
Run as root I get a file in the roots home dir on the /dev/hda1 partition 
called audiodump.wav.  This partition isn't big enought to take a 3 hr show 
and I don't want it there anyway, the script says put the donload in 
/home/ann/rips/ .  ???  Obviously the mp3 conversion fails because the .wav 
is in the wrong place.

It's not a target directory permissions issue.
[root at tri: /home/ann]# ls -l
drwxrwxr-x    2 ann      ann          4096 Jan  2 13:47 rips

Any ideas much appreciated.  I'm using Linux redhat9 and MPlayer 
dev-CVS-050927-16:40-3.2.2
Thanks

---------------------THE SHELL SCRIPT------------------
#!/bin/bash

DATE=`date +%F`
echo "recording"
rm /home/ann/rips/Show*.wav #remove previous show .wav files
mplayer -cache 256 -playlist 
http://www.station.co.uk/radio/aod/shows/rpms/show.rpm -ao 
pcm:file=/home/ann/rips/Show.wav -vc dummy -vo null -really-quiet &
#sleep 10800  #sleep for 3hrs
sleep 120   #sleep for 120sec
kill $! #kill the mplayer job
echo "recording done"
head -17600000 /home/ann/rips/Show.wav >/home/ann/rips/Show1.wav
#if I don't do a 'head' LAME can't find the 3 hour .wav file, I'm guessing 
that it's too big
echo "head done"
lame /home/ann/rips/Show1.wav /home/ann/rips/Show$DATE.mp3
echo "all done :)"
