Hi All

I want my cron job to run at every 2 minutes interval in all hours,
days, months etc.
OS - Sun Solaris
Release Level -5.10

I tried with */2 * * * * filename but it failed.

How to do that?

Regards
Prachet

Try 'man crontab' on your Solaris box to find out the format of each field.

Try this -- all on one line --

0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,49,50,52,54,56,58

* * * * filename

Sure, it looks inelegant, but elegance costs extra. Remember, my
advice is worth every penny you paid for it!

Alternatively, use "at" instead of "cron". Set up a script:

#!/bin/sh
# Script named "myScript"
at now + 2 minutes <<!
/pathTo/myScript
!
.... perform my script functions ...
#end myScript

Hope that's helpful.

Threr is a mistake or limitation in above method, you don't calculate
the time which "myscript" run.
You can add a "&" after "/pathTo/myScript"

It's Vixie Cron syntax if you want to be accurate.

Shades of VAX/VMS batch. It works, but if anything goes wrong so as to
prevent the resubmission you loose your job.
