in thread parallel reading

Nice approach. And my be merged with mine, e.g.:

#!/usr/bin/perl -l use strict; use warnings; my @fh=map { open my $fh, '<', $_ or die "Can't open `$_': $!\n"; $fh } @ARGV; no warnings 'uninitialized'; print while $_=join '', map { chomp(my $line=<$_>); $line } @fh, __END__

However:

  • you should s/undefined/uninitialized/;
  • it may not be fully reliable if empty lines are to be expected in the files.

Update: the second point was a thinko as Zaxo pointed out.
