something like this will read in all the files listed in @files. It also cuts down on repetitive code and allows scalability.

my @files= qw| /path/to/file1 /path/to/file2 /path/to/file3 |; my @allfiles; for my $filename(@files){ open(FILE," $filename") || die "Cannot open $filename: $!\n"; while(<FILE>) { push @allfiles, $_; } close(FILE); }

-p

    Better would be:
    my @files= qw| /path/to/file1 /path/to/file2 /path/to/file3 |; my @allfiles; for my $filename(@files){ open FILE, $filename || die "Cannot open $filename for reading: $!\n"; push @allfiles, $_ while (<FILE>); close FILE; } # Or (and even more Perlish) ... my @files= qw| /path/to/file1 /path/to/file2 /path/to/file3 |; my @allfiles; for my $filename(@files){ open FILE, $filename || die "Cannot open $filename for reading: $!\n"; push @allfiles, <FILE>; close FILE; }
