Run Script every 4 minutes

[dshaw21369]

I would like to run a script every four minutes
this does not work any suggestions?

4 * * * * /export/home/egate/Perl_Development/monitor_log.pl > /dev/null 2>&1

04 * * * * /export/home/egate/Perl_Development/monitor_log.pl > /dev/null 2>&1

Those scripts should run at four minutes after the hour.

Some versions of cron allow an entry like:

*/4 * * * * <script info....>

or

0,4,8,16,20,24,28,32,36,40,44,48,52,56 * * * * <script info....>

Check your manpages on cron and crontab to see if this is available. ______________________________________________________________________

Or try putting a sleep 240 in your script and looping it? Cheers.

let your script DECIDE not cron !!
in cron:
* * * * * script
in script:
#!/bin/sh
case `date +%M` in [135][26]|[024][048])
;; *) exit
;; esac

do the job.... -----------
when they don't ask you anymore, where they are come from, and they don't tell you anymore, where they go ... you'r getting older !
