I checked out Perderabo's datecalc script and it was helpful but still not exactly what I needed.

Code:
#! /usr/bin/ksh
read "yr1?enter start date (yyyy mm dd) - " mo1 da1
start=$(datecalc -j $yr1 $mo1 $da1) ||
{ echo $yr1 $mo1 $da1 is not valid ; exit 1 ; }
read "yr2?enter start date (yyyy mm dd) - " mo2 da2
stop=$(datecalc -j $yr2 $mo2 $da2) ||
{ echo $yr2 $mo2 $da2 is not valid ; exit 1 ; }
while ((start<stop)) ; do
datecalc -j $start
((start=start+1))
done
exit 0
OK, 110 seconds..|
