I would use the magic of @ARGV and <>, and do this: @ARGV = "< $filename" if $opt_f; while (<>) { # do something with $_ } <> reads from the filenames listed in @ARGV, and if @ARGV is empty (which I'm assuming it would be) then <> reads from STDIN. Another approach: if ($opt_f) { open INPUT, "< $filename" or die "can't read $filename: $!"; } else { *INPUT = *STDIN; # like what you were trying } -- Jeff "japhy" Pinyan [EMAIL PROTECTED] http://www.pobox.com/~japhy/ RPI Acacia brother #734 http://www.perlmonks.org/ http://www.cpan.org/ ** Look for "Regular Expressions in Perl" published by Manning, in 2002 ** <stu> what does y/// stand for? <tenderpuss> why, yansliterate of course.
