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
}
