I just found this handy reference site here:

http://www.ibm.com/developerworks/aix/library/au-productivitytips.html

Here was my script that finds the files modified between given dates, and then will tar the ouptut to an archive.

<blockquote> find /path/ -name *.JPG -daystart -newer file.start ! -daystart -newer file.end -print0
xargs -0 tar rvf filename.tar</blockquote>
