    Here's my 2 cents:
    
    I've written a program called dfilter that can extract files from 
    directory contents.  First you take dir contents to a file and then
    type for example:

    dfilter a Apr 01 1991 - May 04 1991 <Dir-contents

    This would show only the files that have arrived between Apr 1 and May 4.
    You can also cut unwanted columns like protection bits etc.  The best
    thing, however, is that there is also a script file provided, that
    can show you only those files that have arrived after your last
    visit to this site.  You can use this system for any number of FTP
    sites.  Below is an example of this, I connect to a site which
    I haven't visited after April 10th:

ftp> cd pub/amiga
250 CWD command successful.
ftp> dir * aachen   ## Take dir contents to a file 'aachen' ##
ftp> !wnx aachen    ## 
                       List the files that have arrived after my last visit,
                       the 10th of April.  Wnx takes the starting date from 
                       a file called .aachen.date .  It scans the file aachen
                       for new files and lists them.  After this, the latest
                       date is written to file .aachen.date.  New files are 
                       written to file .aachen.new 
                    ##

This program can be used in Unix and Amiga environments.  The latest version
1.4 should be in ab20's incomin/amiga.
