how do i change it to for every 30 minutes rather than 30minutes after the hour. May be I was checking it incorrectly. Because my intention is to do it every half hour.

Sorry, I've misspoken - it's every 30mins, e.g. 14:00, 14:30, 15:00 etc...

okay! I found my problem. It's not a problem, I was misinterpreting the minute part.

When we say

30 * * * * test.sh implies it runs 30mins after the hour. Not every 30 minutes. If I want the script to run every 30 minutes then we should say-

0, 30 * * * * test.sh

I tested this logic using short time 1 minute. For ex:
1 * * * * test.sh will run at 1 minute after every hour.

1, 5 * * * * test.sh will run at 1minute after every hour and 5 minutes after every hour.

Radhika.
