AFAIK cron only "understands" minutes. You could make the hourly script to sleep for 30sec and then run another script.

True, because the cron daemon scans the crontab file only once a minute. A 30 second delay will have to be handled programmaticly.

boolean short circuit in shell...

[QUOTE=yusufs;3007393]I want to have a cron which should run every hour.. and another cron to run within the next 30 secs after the first cron is executed.. how to have this ?

configure your crontab entry as

Code:
/some/dir/script1.sh && sleep 30 && /some/dir/script2.sh
the shell evaluates left-to-right to determine the result of the whole expression. If script1 exits non-zero, it won't do the sleep or scrip2.

-c
