I see that you have already received good advice from other monks. I just wanted to mention that item 9 in Basic debugging checklist shows how to use the YAPE::Regex::Explain module to demystify regular expressions. For example, you can see an explanation of your regex by running this
perl -MYAPE::Regex::Explain -E 'say YAPE::Regex::Explain->new("(?:ftp: +\/\/)?\/{5}(a-z_)\/")->explain()'
The output is
The regular expression: (?-imsx:(?:ftp://)?/{5}(a-z_)/) matches as follows: NODE EXPLANATION ---------------------------------------------------------------------- (?-imsx: group, but do not capture (case-sensitive) (with ^ and $ matching normally) (with . not matching \n) (matching whitespace and # normally): ---------------------------------------------------------------------- (?: group, but do not capture (optional (matching the most amount possible)): ---------------------------------------------------------------------- ftp:// 'ftp://' ---------------------------------------------------------------------- )? end of grouping ---------------------------------------------------------------------- /{5} '/' (5 times) ---------------------------------------------------------------------- ( group and capture to \1: ---------------------------------------------------------------------- a-z_ 'a-z_' ---------------------------------------------------------------------- ) end of \1 ---------------------------------------------------------------------- / '/' ---------------------------------------------------------------------- ) end of grouping ----------------------------------------------------------------------

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