In the wrapper, choose whether it is an odd or even week and issue the target commands accordingly. The "choose odd or even" can't be from the beginning of the year, or it will not work across year boundaries, so it needs to be based on absolute time. WEEK=`perl -e 'print 1 & int(time/(60*60*24*7))'` This inaccurately sets WEEK to 0 or 1 (currently 1). Better would be to use one of perl's date/time modules, which do leap years, DST, etc. instead of calculating it yourself. --S ** Posted from http://www.teranews.com **      |
