[gentoo-user] Bash and ACPI issue - laptop lid

[Saphirus Sage <saphirus497@gmail.com>]

I've been trying to setup my laptop to enter ACPI S3 (suspend to ram)
when I close the lid. I currently have the scripts setup as such:
/etc/acpi/events/lid
    event=button[ /]lid.*
    action=/etc/acpi/actions/lid.sh
/etc/acpi/actions/lid.sh
    #!/bin/bash
    for i in $(cat /proc/acpi/button/lid/LID/state | grep -o closed); do
        if [ $i = "closed" ]; then
        /usr/sbin/pm-suspend
        fi
        if [ $i != "closed" ]; then
        sleep 5
        fi
    done
The issue I've run into is that this will cause my laptop to suspend to
the RAM upon any change in the lid state, irregardless of if it is open
or closed. I tried to be more specific by utilizing the suffix of the
event, but it's incremental, which is a bit beyond my abilities. Any
suggestions to make this suspend only when the lid is closed?
