I want to run a cron job only once a month. The problem is the computer is

cron tab as this below is an "or" condition as it has entries in Days of the

5 18 1 * 2 rsync -av ...
so it will run on days 1 or Tuesday of each months.
Is it possible to create "and" condition, eg. run it on Tuesday between days 1
to 7; depend on which day Tuesday falls on?
You can run it every Tuesday and check for day of month externally:
5 18 * * 2 test $(date +%d) -le 7 && rsync -av ...
or run it on
5 18 1-7 * * and test for Tuesdays, but the former gives less useless
invocations.

Thanks, very cleaver, I knew there must be a solution.
