i am writing a code where i have to find version associated with the name from a file. i am trying below code but the pattern match is not working. the file /home/test.txt contains multiple entries like below:

Anls/01.00/windows
abc/02.00/windows
core/03.00/windows
route/04.00/windows
.

my $file = "/home/test.txt";
        if (-e $file) {
            my @list = ("Anls", "core", "route");
            open(FH, '<', $file) or die $!;
            foreach my $x (@list) {
                while(<FH>){
                  my $pattern;
                  if (defined($pattern) && ($pattern =~ /$x\/(.*)\/(.*
+)/)) {
                      my $version = $1;
                      print "$x: $version\n";
                  }
                }
            }
            close(FH);
        }
