Pardon the not-very-useful wild guess, but wasn't there a nice example program in some old Camel Book that would print out an output like

  /home/mjd/foo.c
  /home/mjd/bar/baz/foo.c
  /home/mjd/bar-1.0/baz/foo.c
  /userhomes/m/j/mjd/bar-1.0/baz/foo.c
  /mnt/homevol/m/j/mjd/bar-1.0/baz/foo.c
[download]

as it progressively resolved the symlinks in higher and higher components of a path?

I thought it might have been one of those abandoned items in the Perl source eg/ directory, but I couldn't find it there, so the Camel Book was my next guess.

Addendum: This looks kinda interesting too.

• 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.
