Uhm, the same way as you do in non-binary files? If the file is small: open the file read/write, read in the file (in a scalar), insert "+" wherever you want it, seek back to the beginning of the file, write the scalar, close the file. If the file is large, open a temporary file for writing, open the original file for reading, read from the file up to the point where you want to insert the "+" while writing what you've read (in chunks) to the temporary file, write "+" to temporary file, read rest of file while writing it to the temporary file, close both files, move temporary file to original file.

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