RE: cron job

You'll need to make 3 cron jobs:

the first will put the second in place at whatever time you choose

the second will be a script that kicks off every minute, runs a command, sleeps for 30 secs, then runs the command again...

the third will get rid of the second...

RE: cron job

So, do you want it written for you? Not to be rude, but the more you put in, the more you get out. For what you asked, I think you got a pretty reasonable response. What the 2nd anonymous suggested will work. If you need more info on Cron jobs, look at this:

What is it that the script does? Will it take longer than 30 sec. to complete? Not that this would effect anything, just curious.

RE: RE: cron job

to add a cron job:
$> crontab -e
then type in the data...
the "data" is:
|`Min. to be executed
| |`Hour to be executed
| | |`Month to be executed
| | | |`Week day to be executed
| | | |
* * * * <command>
if you want something to run evrey min. it would be:
*/1 * * * /some/program/
to put the output into /dev/null:
*/1 * * * /some/program/ >/dev/null 2>&1
