alternately, to avoid len(file1) x len(file2) loops,

use autodie; use warnings; use strict; my (@data1, @data2) = (); my ($fh, $l, $n); open $fh, "<", $ARGV[0]; while(<$fh>) { ($l, $n) = split; push @data1, [ $l, $n ]; } close($fh); open $fh, "<", $ARGV[1]; while(<$fh>) { ($l, $n) = split; push @data2, [ $l, $n ]; } close($fh); foreach my $row1 ( @data1 ) { foreach my $row2 ( @data2 ) { my ($l1, $n1, $l2, $n2) = (@$row1, @$row2); my $match = $l1 eq $l2; print "$l1 from FILE1 with number $n1 and $l2 from FILE2 with +number $n2" . ($match ? '' : " DO NOT") . " match\n"; } } __END__ A from FILE1 with number 1_1 and A from FILE2 with number 2_1 match A from FILE1 with number 1_1 and B from FILE2 with number 2_2 DO NOT m +atch A from FILE1 with number 1_2 and A from FILE2 with number 2_1 match A from FILE1 with number 1_2 and B from FILE2 with number 2_2 DO NOT m +atch B from FILE1 with number 1_3 and A from FILE2 with number 2_1 DO NOT m +atch B from FILE1 with number 1_3 and B from FILE2 with number 2_2 match C from FILE1 with number 1_4 and A from FILE2 with number 2_1 DO NOT m +atch C from FILE1 with number 1_4 and B from FILE2 with number 2_2 DO NOT m +atch

this will save a lot of time if the files are significantly larger than 4 and 2 lines, respectively. though it will end up using more memory...

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
