Well I'm not sure this will work because the code makes the program go down the directory first, not across. Based on your idea it would have to keep a record somehow of the $oldir variable for when it finally finished going down the tree and came back to start on the next level. This requires it to keep a kind of memory of the tree and what it has or hasn't done. There must a simpler way.

BUT ... your idea has merit and something I'd considered also - your post has made me rethink it. If the number of path seperators is greater than $depth then don't push to the stack. That may work. I just don't like using relying on counting "\" in strings as a reliable method of keeping track of depth. If by chance a directory has that character in it, the routine will fail.

• 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).
