Probably best to use $date +%Y%m%d Which (for today) would give 20030123 and for tomorrow, 20030124, etc., which means that it can be sorted based on the extension and come out in logical order. BTW, someone else (also) suggested currdate=`date -s +%Y%m%d` mv myfile myfile.$currdate which is NOT what you want; the -s will mess it up; probably just a typo, leave out the -s and that works.
