I am tasked with syncing two directorys, sort of.  I have a large directory
with a ton of files (10K+) of which I want a subsection copied over to
another directory.  Luckily, all the files I want to move are prefaced by
known strings (foo, bar, boz), so I wrote a 5 line perl script that slurps
up
a config file that lists all the prefaces we want to copy, then does a

foreach $preface ($blah){sytem("cp $preface* /target") or die;}.

That works great.  However, next time I run the script, it copies all the
same files over again, plus the few additional files.  This is significant
because even the subsection is 1500+. My question is: how do I copy only
the
new files?  I couldn't find an option in man|info cp that would look to see
if the files are already there and skip if they are, though there are a ton
of 'overwrite|symlink|hardlink|whatever' options.  Has anyone done this
before?  Am I using the Right Tool for the Right Job?  Any help would be
greatly appreciated.
