Can you give the steps of how do it?

Quote:
#! /usr/bin/ksh
day=$(date +%d)
if ((day <= 7)) ; then
exec somecommand
fi
exit 1
That wont work as cronjob will run first 7 days. But I want cronjob to run only once (wed) in a month..

Your cron if you have set on wednesdays will only run all wednesdays, the test is to execute if day is less than 8 (first week), else you execute on the first 7 days of the week and test if day is wednesday

Code:
00  5 * * 3          /sm/cron/bin/yourplannedJob

will run every wednesday...
If you test for days less than 8, you are sure to be in the first week of the month
