Regex not matching

perl_mystery has asked for the wisdom of the Perl Monks concerning the following question:

Expandplf_updates.txt:-
/****************************ORPHANED FILES***************************
+/
  //source/modem/hdr/cp/rel/07.01.00.13.20/inc/hdr.c#2 
 //source/modem/hdr/cp/rel/07.01.00.13.20/inc/hdrscmgmmcdp.h#2 
/*************************** FILES IN VU's***************************/
 /******************************* PLF's******************************/
 
my $expand_line = <Expandplf_updates.txt>;
open my $FH, '<', "$expand_line" or die "could not open $expand_plf - 
+$!"; 
while (<$FH>) {
    chomp;
        print "IN\n";
    next unless ( m:(\/\/.+?)#(\d+)$: );//why is the above input not m
+atching this line.

    print "\nMATCH DATA:$1 $2";//doesnt print this

Why do you beat your wife? Which is to say it does match. Perhaps your actual data has some kind of hidden character between the number and the end of the line (spaces? CR?)	[reply]

"Why do you beat your wife?" I realize this is used figuratively but I think we can all agree there is a better way to express a point than to use a violent image against women. A text search shows it's been used before on the site so you're not the first to include it in a post. Even without malice or literal meaning behind it the phrase is offensive. Please, to anyone who has used it before or would use it in the future, consider another way to illustrate your point.	[reply]

Isn't it rather a reference to traditional quote (see e.g. Loaded_question) rather than the violent image?	[reply]

No. If you have `od`, you could dump your file using `od -c file` [download] Or you could use Perl. `perl -ple's/\\/\\\\/g; s/([^\x21-\x7E])/sprintf(qq{\\x{%X}}, ord($1))/ +eg;' file` [download] (Switch «`'`» for «`"`» for the Windows shell.)	[reply] [d/l] [select]
