Actually, changing "/a1/a2/../a3" to "/a1/a3" can somethimes get you to a different directory. This is why File::Spec doesn't do that. This has to do with symbolic links and other not-strictly-tree-like possibilities in Unix-like file systems (automounted directories is another).

For example, if "/a1/a2" is a symbolic link to "/b1/b2/b3" then "/a1/a2/../a3" should really become "/b1/b2/a3". And there is no "good" way to do that. One reasonable way is chdir("/a1/a2/../a3"); $path= getcwd(), but that doesn't always work either (though I'm getting old and tired and now usually feel that getcwd() not working is a good excuse for my script to not work as well).

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.
