 You have a useless use of cat in there.
 
 But more importantly: does perl not allow something like
 
    open(DIGEST, "| xargs digest $sum |")
 
 so you can just feed the file list through? Or is Perl paralyzed by
 the same foolishness that disallows this kind of thing using popen(3)?
 
 (And failing that, doesn't Perl have mkstemp?)
