For explanations of regexes use japhy's ever helpful YAPE::Regex::Explain e.g

use YAPE::Regex::Explain;

print YAPE::Regex::Explain->new(q<^(.*)\/([^\/]*)>)->explain();

__output__

The regular expression:

(?-imsx:^(.*)\/([^\/]*))

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):
----------------------------------------------------------------------
  ^                        the beginning of the string
----------------------------------------------------------------------
  (                        group and capture to \1:
----------------------------------------------------------------------
    .*                       any character except \n (0 or more times
                             (matching the most amount possible))
----------------------------------------------------------------------
  )                        end of \1
----------------------------------------------------------------------
  \/                       '/'
----------------------------------------------------------------------
  (                        group and capture to \2:
----------------------------------------------------------------------
    [^\/]*                   any character except: '\/' (0 or more
                             times (matching the most amount
                             possible))
----------------------------------------------------------------------
  )                        end of \2
----------------------------------------------------------------------
)                        end of grouping
