I'm surprised no one's mentioned tr///; You'll still have to give it two ranges, but it works well.. It also has the added advantage (so far as i know) of being more efficient than s///;
You can give it the hex values, for example:
$string =~ tr/\x00-\x04\x07-\x09//d;

This'll get rid of the range \x00 through \x04, leave characters \x05 and \x06, and delete the range \x07 through \x09...
Of course.. it's too early for me to think straight, so the ranges given are bogus, but you get the idea..

• 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.
