now I can parse through and get the ascii

That makes it sound like you want to read through a file that contains both "printable" and "non-printable" byte values, and display only the printable (ascii) stuff. On unix, there is a command called "strings" to do exactly that.

A perl implementation would be something like this (assuming the file is not too big to hold in memory):

$_ = do { local $/; <> };
s/[^\t\n\r -~]+/\n/g;
print;

You could tweak that to print only strings that are some minimum length, etc. Anything else you know about the binary file (e.g. strings of interest are all terminated by null bytes, or something like that) could be used to good effect in making sure you only print the interesting parts.

• 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).
