Hi.
Here is the current entry in my cron file..

*    *    *    *    *   sh /ffp/start/torrentwatch.sh

Is that the correct syntax?  or is it only supposed to be one space instead of a tab between the asterisks?

You need to specify a bit more than that unless you want to run the script every minute. Have a look at the Wiki for example -> http://en.wikipedia.org/wiki/Cron#Fields
As RunaR already stated "*/30 * * * * /ffp/start/torrentwatch.sh" will be ok to run the script every 30 minutes on your machine. One space between the asterisks is sufficient but tabs should work as well.

Use "crontab -l" to check if the job was successfully added to the crons task list.

It would also be a good idea to specify a log file so you can see when the script was run and what it did.

I have the line added as:
*/30 * * * * /ffp/var/scripts/torrentwatchdog.sh >> /mnt/USB/torrents/.torrentwd.log 2>&1

It runs every 30 minutes. sh is not needed. output goes to a log file. The exacutable bit on the script should be on (chmod a+x <filename>). /ffp/start is not the ideal place to put the file. The script will also run at startup.

the other thing i was wondering, was which crontab is being run?  the one included with the ffp script? or the one that is included on the dns box itself?  I looked and saw 2 folders with that command, pointing to two different busybox executables..   how do I verify which one is running the job? and does it make a difference?


does the */30 at the beginning of the crontab line make it every 30 mins?  therefore if i make it */5 it will run every 5 mins? 

I have used linux quite a bit, but never have had to run jobs using cron, so i kinda on a beginner level in that regard..

thanks!

Thanks for your help, that seems to have done the trick!
