Very fast response on this one, and yes, a simple answer, right out of the
crontab man page:
The cron program runs the command named in the sixth field at the
specified
date and time. If you include a percent sign (%) in the sixth field, cron
treats everything that precedes it (in that field) as the command invoca-
tion, and makes all that follows it available to standard input, unless
you
escape the percent sign (\%) or double quote it ("%").
Working entry is:
45 13 * * * script.ksh arg1 -arg2.`date +\%y\%m\%d`
Thanks to Dr Blinn, Pat O'Brien, Martin Moore, Paul Sand, Ken Peacock, Dan
Harrington and George Gallen.
My apologies for asking a question so obviously documented.
Bill
