Schedule to run every 3 minutes - CRONTAB

Hello all,

I want to run a script every 3 minutes in os level and to send mail.

I scheduled in crontab as

3 * * * * /mnt1/monitorscripts/testdbstart.sh

I got mail every one hour and I confirmed that the script is running every 1 hour which doesn't meet my requirment.

Where I am wrong? Did I scheduled in crontab properly?

Please advice

OS: sun solaris 5.2

Thanks and Regards,
Prashanth

Your example is for 3mins after EVERY HOUR...

Do a man on crontab for more info:

crontab Entry Format
A crontab file consists of lines of six fields each. The
fields are separated by spaces or tabs. The first five are
integer patterns that specify the following:

minute (0-59),
hour (0-23),
day of the month (1-31),
month of the year (1-12),
day of the week (0-6 with 0=Sunday).


3,6,9,12,15,youGETtheIDEA * * * * /mnt1/monitorscripts/testdbstart.sh

thats right!

Its every 3rd minute that you need to mention... rest is good:


3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60 * * * * /mnt1/monitorscripts/testdbstart.sh

did that work!
