¿Por qué mi script BASH se ejecuta dos veces? Estoy usando launchd

Tengo un error asociado con este agente launchd. Hay un agente listado en la lista launchctl, y llama a mi script bash, llamado rc.wakeup, cada vez que el mac se despierta del modo de espera. Sólo hay una copia de este script bash. El código en el script de bash no se repite. A pesar de esto, el script bash se está ejecutando dos veces en su totalidad. ¿Por qué?

He creado un script bash de instalación y un script bash de desinstalación. Los he estado ejecutando en serie para intentar que ambos scripts funcionen, por lo que cualquiera puede usar este programa. Creo que la instalación / desinstalación incorrecta de estos archivos ha causado el problema, aunque no tengo idea de por qué lo haría.

Aquí está el plist:

Aquí está el script de instalación que utilizo para instalar el programa:

Aquí está el script de desinstalación:

Aquí está el script real que se está ejecutando cuando se apaga la computadora:

for user in 'echo 'show State:/Users/ConsoleUser' | scutil | awk     '/kCGSSessionUserNameKey/ { print $3 }''; do
        home='eval echo ~$user'
        if [ -x "$home/.wakeup" ]; then
                logger -t $0 "executing .wakeup of user $user"
                su - $user -c "$home/.wakeup"
        fi
done

#The following is the MySecureView script used to capture the picture and its information.
cd ~/mysecureview

# take a picture.
./imagesnap

#get the log index. Create a variable for and iterate the index.
numPics=$(cat ~/mysecureview/num.txt)
numPics=$[numPics+1]
jpg=".jpg"
index="$numPics$jpg"

#We only allow 100 log entries to exist at a time.
if [ $numPics == 100 ]; then
        numPics=1 
fi

#temp storage for the newest picture.
cp ~/mysecureview/snapshot.jpg ~/mysecureview/pics/$index
