It may be a problem with your quoting.
Code:
ldcount="grep -c "stat_load" $LOAD_STATUS_DIR"

You have nested double quotes..

I think you want something like:
Code:
ldcount="grep -c stat_load $LOAD_STATUS_DIR"

If you don't want the inner double quotes to be evaluated, u need to use single quotes, or escape the double quote.

One thing to learn is if you use single quotes, special characters will not be evaluated. If you use double quotes, then special chars will be evaluated. Single quotes are used to hide the meaning of special characters like $, *, \, !, ", ` and /. Any characters between single quotes, except another single quote, are displayed without interpretation

CPANPLUS::Shell(3pm)					 Perl Programmers Reference Guide				      CPANPLUS::Shell(3pm)

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

	   my $ui      = CPANPLUS::Shell->new();
	   my $name    = $ui->which;	    # Find out what shell you loaded

	   $ui->shell;			    # run the ui shell

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.
