( [id://3333]=superdoc: print w/replies, xml ) Need Help??

I'm guessing they're octal by some weird default. I was able to make similar output making up a dummy file using that presumption (entering his numbers using hexl-mode in emacs) that produced similar output on OS X with the default /usr/bin/hexdump. I'm partial to od -xa myself.

$ hexdump -c foo 0000000 \0 \0 001 257 \n 344 \0 003 \0 \0 \0 s \0 006 002 26 +7 0000010 $ od -xa foo 0000000 0000 af01 e40a 0300 0000 7300 0600 b +702 nul nul soh af nl e4 nul etx nul nul nul s nul ack stx +b7 0000020

Edit: Derp, his \a should of course be 0x07 not \n / 0x0a. I need moar caffeine . . .

Title:
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 How to display code and escape characters are good places to start.
