Here we have a piece of seriusly injured code, thank heavens we have the comments so we can repair it!
#!/usr/bin/perl -w use strict; $_ = "A silly obfuscation:"; # Something to start with. $ # A buck for your thoughts? 0=0 # Yes, obviusly it is... ;$ # Got it backwards? _="utaohrpr akr"; # Special variable, filled with gib +berish? map # Sure could use one here. {$,.='$'.++$0.$_} # Anonymous Hash? split # I'm about to... '' # An empty string? ;$ # Again?! _= # The gibberich here? "Dog and Pony" # Hey, that is me! ;$"=" # Can you quote an assignment? Js nte elhce # Barewords allowed? ";$" # Interpolating backwards var? =~s # For my tilde POD? / + # \w* ?\w* ?\w* ?\w* ?\w*\?//g;# Division plus a match inside '#'s +? ;s # Oops, should be a dollar, not 's' +? /$_/ # Matches itself? $"/ # Unterminated String constant? ;s # Same mistake again? / + # \w* ?\w* ?\w* ?\w* ?\w*\?//g;# Vaguely familiar....? $0=".";$" # Program is now current dir and ou +r special var? =~ # Another, but empty tilde POD? s/($0)/($1)/g; # Replacing our program with itself +? eval("s/\n$\"/$,/"); # Always, always use an eval in an +obfu! :) print; # Now, what did we get...?
This is also my very first real try at something like this, so I am a bit anxious to hear what you all think?

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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 or How to display code and escape characters are good places to start.
