#!/bin/ksh

# Used to copy regular files from one directory to another
# when the number of files is so large that the regular cp
# cmd blows up with "arg list too large" error.
# 
# Parameter 1 is the source dir - use no wildcard in this parameter.
# Parameter 2 is the filename pattern - MUST DOUBLE-QUOTE if you use ANY wildcard.
# Parameter 3 is the destination dir - use no wildcard in this parameter.
#
# It's probably safest to cd into the source dir and simply provide
# a dot (.) as the 1st parameter, and then your desired filename pattern
# ENCLOSED IN DOUBLE-QUOTES as the 2nd parameter and finally
# the destination dir as the 3rd parameter. Don't forget to provide trailing slashes
# on directory names just to be safe.
