$return{"objdump"} =~ s/.*?([0-9a-f]{8}|$)/$1/gs;
print "\\x$_" for $return{"objdump"} =~ /../g;

  • 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.
