The english language stating the problem is already longer than your source code, I don't know if it can be made truly short. But you're right, grep | grep | grep | grep isn't terribly efficient. You could do it in several case statements and use ${#string} to get its length, or pile it all into an awk statement, which isn't terribly efficient itself, but better than five greps, and easier to see what you're doing.
Code:
if echo "$PASS" | awk '/^[_a-zA-Z]/ && /[a-z]/ && /[A-Z]/ && /[0-9]/ && (length($0) > 8) && (length($0) < 16) { X=1 } END { exit(!X) }'
then
echo "Password is OK"
else
echo "Password is not OK"
fi

CPANPLUS::Shell(3) User Contributed Perl Documentation CPANPLUS::Shell(3)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.

Please report bugs or other issues to <bug-cpanplus@rt.cpan.org<gt>.
