-#!/bin/bash
-# finddate.sh
-# author:  Luke Lin    phone:  457-5047           24 June 1998
-# author:  Daniel Wesloh                          30 January 2024
-# abstract:  This script looks in ether forward or backward in time to
-# generate  either a variable containing sequential date/time stamps
-# for a period up to a month or just the date/time stamp occurring
-# at the end of such a period.
-# Time stamp is in the form yyyyddmm.  The script should be good for many
-# years. Leap years are accounted for.  Years go 1998, 1999, 2000, 2001,
-#   2002, 2003, ....
-# etc.
-#
-# usage:  examples assume today's date is 19990929.
-# To generate a sequence looking 10 days forward then execute:
-#     list=`sh /nwprod/util/scripts/finddate.sh 19990929 s+10`
-# To generate just the date/time 10 days from now then execute:
-#     list=`sh /nwprod/util/scripts/finddate.sh 19990929 d+10`
-# To generate a sequence looking 10 days backward then execute:
-#     list=`sh /nwprod/util/scripts/finddate.sh 19990929 s-10`
-# To generate just the date/time 10 days ago then execute:
-#     list=`sh /nwprod/util/scripts/finddate.sh 19990929 d-10`
-# list will contain 10 time stamps starting with 19990929.  Time stamps
-# are separated by blanks.
