Re^3: Text filTer and assign

I humly think you need a regex playfield: as usual i suggest two tools:

I find also YAPE::Regex::Explain useful:

>perl -MYAPE::Regex::Explain -e " print YAPE::Regex::Explain->new(qr/\
+[\d+\.\d+\sGB\s\/\s\d+\.\d+\sGB\]/i)->explain();"
The regular expression:

(?i-msx:\[\d+\.\d+\sGB\s/\s\d+\.\d+\sGB\])

matches as follows:

NODE                     EXPLANATION
----------------------------------------------------------------------
(?i-msx:                 group, but do not capture (case-insensitive)
                         (with ^ and $ matching normally) (with . not
                         matching \n) (matching whitespace and #
                         normally):
----------------------------------------------------------------------
  \[                       '['
----------------------------------------------------------------------
  \d+                      digits (0-9) (1 or more times (matching
                           the most amount possible))
----------------------------------------------------------------------
  \.                       '.'
----------------------------------------------------------------------
  \d+                      digits (0-9) (1 or more times (matching
                           the most amount possible))
----------------------------------------------------------------------
  \s                       whitespace (\n, \r, \t, \f, and " ")
