Because this is Perl, There Is More Than One Way To Do It:

use strict;
use warnings;

my $file = "/home/test.txt";

# Store the list of desired names in a hash, with a true value for each.
my %list = map { $_ => 1 } qw{ Anls core route };

open my $fh, '<', $file or die "Failed to open $file: $!";
while ( <$fh> ) {

  # Use split() to break $_ on slashes. Save only first two parts.
  my ( $x, $version ) = split /\//;

  # Print if hash entry {$x} contains a true value. Non-existing entries are false.
  print "$x: version $version\n" if $list{$x};
}
close $fh;

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
