Hi,

on linux works:

*/2 * * * * command

Hi,

in hpux */1 doesn't work
I think you have to do:

0,2,4,6,8,10,12,14,16 .... 58 * * * * command

Hi amit,

#cd /usr/spool/cron/crontabs
#vi root.tmp (if you want to run this command as root. If you want to run it with another user: vi .tmp)

...add the following line...

2,4,6,8,10,...,58 * * * * /.../command.sh

...save the file...

#crontab root.tmp

Best regards,

crontab -e >> /tmp/cronfile1

Make the necessary changes to /tmp/cronfile1
whereever you feel comfortable

0 2 4 6 8 .... 58 * * * *

DO crontab /tmp/cronfile, this will write a new root cron file for you.
This is what I have used to make changes.

Thanks

Amit,

I would prefer to prepare a script with "sleep 120".

Sorry,
After you make necessary changes to /tmp/cronfile1

do

crontab /tmp/cronfile1

Please note the change it's cronfile1 to do corntab on.

Thanks
Prashant
