Cron Job Syntax for a task in seconds


Hi:

I have two important questions to me.

1. I setup a system Debian recently, and as an additional user, When I right click on the Devices Icons like HD, Cdrom, DVD-Rom, I get a menu panel that states only Actions -> Zip, or Zip & E-mail.

I want extra ones, Like Rename, Move-toTrash, Actions -> Play Music, Open With.

How do I create or borrow this from the root?

2. I want the exact cron job syntax for performing a task every 10 or 20 seconds

*/6 * * * * cp something

is this possible?

Thanks
AJ

First off, that would execute the commands every 6 minutes. Secondly, cron only has 1-minute resolution, and therefore is not suitable for executing something every 10 or 20 seconds. If you want that, add this to your crontab:
Code:
@reboot /PATH_TO_SCRIPT_BELOW
and create a script containing:
Code:
#!/bin/bash
while true 
do <<EXECUTE YOUR COMMANDS HERE>>
sleep 20 #this will make the next iteration 20 seconds after the previous
done
