Crontab not playing
This is my crontab:
Code:
MAILTO=""

# m h  dom mon dow   command
# Check to see if the fridge door has been left open
* * * * * fridgedoor 

#Get temperature readings from fridge and save to monthly file in Downloads
30 0,4,8,12,16,20 * * * fridge 
40 0 * * * sendfridge

* * * * * fridgedoor doesn't work
But the other two (fridge and sendfridge) do!

Fridgedoor is:

Code:
REAL=$(/usr/bin/digitemp_DS9097 -a -q -o"%.0C" -c /etc/digitemp.conf)
if [ "${REAL}" -ge 1 ] ;then
play /home/brafferton/Downloads/fridge.wav    
play /home/brafferton/Downloads/fridge.wav    
play /home/brafferton/Downloads/fridge.wav    
fi

Entering "Fridgedoor" on the command line works perfectly, but not in crontab

Any suggestions?

crontab does not have the same environment variables (the PATH in this case) that you personally have when you login. Specify the entire filename: /path/to/fridgedoor

If fridgedoor is a script be sure to put things like this on top
Code:
#!/bin/bash
/path/to/my/home/.profile
# add other variables here
# .. rest of code

Didn't seem to make any difference,
All three scripts are in the /usr/bin directory, and the other two work fine.

They do have the bin bash line on top, but the forum did something wierd with the typeface whenever I tried to include the first line of the script, so I deliberately left it out.

---------- Post updated at 05:14 PM ---------- Previous update was at 04:19 PM ----------

For some odd reason, it sort of worked when I did a restart - after updating/upgrading.
On editing crontab afterwards, I found that the line had not been inserted.
So I started again, and the damn thing worked.
Sorry to waste your time, but thanks for the info.
