Crontab won't run.

If someone could shed some light on this for me, I would greatly appriciate it.

I basically just need the crontab to run a command "flexget execute" once every 6th hour.

edit with crontab -e (ctrl+o = save, ctrl+x = quit)

and I guess it should look something like "0 */6 * * * /usr/local/bin/flexget >/dev/null"

remember to always leave a empty line at the bottom.

For some reason, that didn't do it. It still won't autorun. How can I tell the crontab to run "flexget execute" automatically?

Are you sure it's executable, else do chmod +x /usr/local/bin/flexget

Not sure if it's executable or not, I'm not experienced with this system. If I run the flexget execute command, it executes the command correctly though, which is why I thought it would work.

I just did this now:

# chmod +x /usr/local/bin/flexget

Can I type something to test the crontab, to see if it works, or do I just wait 6 hours every time to check? :)

Did you reload cron after doing the modification ? ( /etc/init.d/cron restart ) Cron checks updates on config files only on start I think, at least I've been taught to restart with each modification.
You can also paste your file to the /etc/cron.hourly or /etc/cron.daily if you are not in need for a special timer.

PS : you cron will execute "flexget" not "flexget execute" is any different for this command ?

When testing I set on minute timer and make sure the script has some kind of output, if it works I change the timer and the output (if necessary). Maybe there is a better way to do it though.

# /etc/init.d/cron restart
Restarting periodic command scheduler: cron.

Yes, the command is very different. It has to be exactly "flexget execute".

I don't really need a special timer. Once a hour is perfect too. How do I do that exactly? :)

Then you must have execute as your first argument: "0 */6 * * * /usr/local/bin/flexget execute >/dev/null" for every 6'th hour or for one every hour: "0 * * * * /usr/local/bin/flexget execute >/dev/null"
