close(FH);
you have a lot of extra spaces in your regex

Code:
$line=~/^(\w+)_\s+_(\d+)_\s+_(\d+)_\s+_(\d+)$/;

why not ..
Code:
my ($tbl_spc,$max_size,$free_size,$max_block,$pctfree) = split(/\s+/, $line);

gimp::pod

Pod(3)							User Contributed Perl Documentation						    Pod(3)

NAME

       Gimp::Pod - Evaluate pod documentation embedded in scripts.

SYNOPSIS

	 use Gimp::Pod;

	 $pod = new Gimp::Pod;
	 $text = $pod->format ();
	 $html = $pod->format ('html');
	 $synopsis = $pod->section ('SYNOPSIS');
	 $author = $pod->author;
	 @sections = $pod->sections;

DESCRIPTION

       "Gimp::Pod" can be used to find and parse embedded pod documentation in gimp-perl scripts.  At the moment only the formatted text can be
       fetched, future versions might have more interesting features.

METHODS

       new return a new Gimp::Pod object representing the current script or undef, if an error occured.

       format([$format])
	   Returns the embedded pod documentation in the given format, or undef if no documentation can be found.  Format can be one of 'text',
	   'html', 'man' or 'latex'. If none is specified, 'text' is assumed.

       section($header)
	   Tries to retrieve the section with the header $header. There is no trailing newline on the returned string, which may be undef in case
	   the section can't be found.

       author
       blurb
       description
       copyright
	   Tries to retrieve fields suitable for calls to the register function.

       sections
	   Returns a list of paragraphs found in the pod.
