If you are looking specifically for days in the current month (as opposed to a more general last-word-in file search), the following is one of several ways to produce it: if [ `cal | grep -c 31` == 1 ]; then echo 31 elif [ `cal | grep -c 30` == 1 ]; then echo 30 elif [ `cal | grep -c 29` == 1 ]; then echo 29 elif [ `cal | grep -c 28` == 1 ]; then echo 28 else echo Cal did not produce a calendar. fi HTH, and have a _great_ day! -- Ralph.
