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);

build-lives-rfx-plugin(1)				      General Commands Manual					 build-lives-rfx-plugin(1)

NAME

       build-lives-rfx-plugin - builds rendered effects for LiVES

SYNOPSIS

       build-lives-rfx-plugin script_name [plugin_dir] -get section file

DESCRIPTION

       This perl script is used by LiVES to compile an RFX (rendered effect) plugin for LiVES. It is generally called from build-lives-rfx-plugin-
       multi for a script which has a language code representing LiVES-perl. The script_name must be  the  full  (absolute)  path  to  the  plugin
       script,	and  plugin_dir  can  be  used to specify the output directory where the compiled plugin should be generated. If plugin_dir is not
       defined then /tmp is assumed.

       The second variant with -get is used to print out a script section from a plugin script to stdout. It is generally only used internally	by
       LiVES.

       Return values The script returns the following values

       0 - success 1 - the value of a trigger was greater than the number of parameters 2 - a value could not be read from the script file 3 - the
       language code of the plugin script was not equivalent to LiVES-perl 4 - the API version level of the plugin script  was	invalid  5  -  the
       <define> section was missing from the plugin script
