why isnt cron working?

Shell Programming and Scripting
1

I am using Ubuntu linux desktop, and I am trying to schedule a sheel script to run every 10minutes.

These are the steps I have taken:

crontab -e

added and saved this line to the file

# m h  dom mon dow   command
*/1 * * * * /home/enzo/Desktop/dlrecentuse

restarted cron:

 sudo /etc/init.d/cron restart

nothing is happening, any ideas?

2 
*/1 * * * * /home/enzo/Desktop/dlrecentuse

That doesnt make sense.

* * * * * /home/enzo/Desktop/dlrecentuse

That runs every minute.

*/10 * * * * /home/enzo/Desktop/dlrecentuse

Runs every 10 minutes

You dont have to restart cron after changin.

Look in cron log in /var/log to see if there are any errors.

*/2 would be every 2 mins, */5 every 5 mins...etc...

I have a related question if you know -
if */10 is every 10 - is it on 00, 10, 20 etc?

what if you want to run every 10 mins starting on 02 - 02, 12, 22, etc?
