Perchè il mio script BASH viene eseguito due volte? Sto usando launchd

Ho un plist associato a questo launchd agent. C'è un agente elencato nella lista launchctl, e chiama il mio script bash, chiamato rc.wakeup, ogni volta che il Mac viene riattivato dal sonno. C'è solo una copia di questo script bash. Il codice nello script di bash non viene ripetuto. Nonostante questo, lo script di bash viene eseguito due volte nella sua interezza. Perché?

Ho creato uno script di bash di installazione e uno script di bash di disinstallazione. Ho eseguito questi in serie un tentativo di far funzionare entrambi gli script in modo che questo programma possa essere utilizzato da chiunque. Credo che l'installazione / la disinstallazione impropria di questi file abbia causato il problema, anche se non ho idea del perché.

Ecco il plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"    "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

    </array>
    <key>RunAtLoad</key>

    <true/>
</dict>
</plist>

Ecco lo script di installazione che uso per installare il programma:

#!/bin/bash
sudo mkdir -p /usr/local/sbin /usr/local/share/man/man8
sudo cp ~/Desktop/mysecureview/sleepwatcher_2.2/sleepwatcher /usr/local/sbin
sudo cp ~/Desktop/mysecureview/sleepwatcher_2.2/sleepwatcher.8     /usr/local/share/man/man8

mkdir ~/mysecureview
mkdir ~/mysecureview/log
mkdir ~/mysecureview/pics

cp ~/Desktop/mysecureview/imagesnap-master/imagesnap ~/mysecureview/imagesnap

mkdir ~/Library/LaunchAgents
cp ~/Desktop/mysecureview/sleepwatcher_2.2/config/de.bernhard-baehr.sleepwatcher-20compatibility.plist ~/Library/LaunchAgents/de.bernhard-baehr.sleepwatcher-20compatibility.plist

launchctl load ~/Library/LaunchAgents/de.bernhard-baehr.sleepwatcher-20compatibility.plist

sudo cp ~/Desktop/mysecureview/sleepwatcher_2.2/config/rc.wakeup /etc/rc.wakeup
sudo cp ~/Desktop/mysecureview/sleepwatcher_2.2/config/rc.wakeup /etc/rc.sleep

cp ~/Desktop/mysecureview/num.txt ~/mysecureview/num.txt
cp ~/Desktop/mysecureview/logs.txt ~/mysecureview/logs.txt
cp ~/Desktop/mysecureview/compile.bash ~/mysecureview/compile.bash
cp ~/Desktop/mysecureview/uninstall ~/mysecureview/uninstall

mkdir ~/mysecureview/logs.txt
echo "========================"
echo "~Installation Succesful~"
echo "========================"

ecco lo script di disinstallazione:

#!/bin/bash
launchctl unload ~/Library/LaunchAgents/de.bernhard-baehr.sleepwatcher-20compatibility.plist;
rm ~/Library/LaunchAgents/de.bernhard-baehr.sleepwatcher-20compatibility.plist
sudo rm /etc/rc.wakeup
sudo rm /etc/rc.sleep

sudo killall sleepwatcher
sudo rm -rf /Library/StartupItems/SleepWatcher

launchctl unload de.bernhard-baehr.sleepwatcher
launchctl remove de.bernhard-baehr.sleepwatcher

rm ~/mysecureview/num.txt
rm ~/mysecureview/compile.bash
rm ~/mysecureview/imagesnap
rm ~/mysecureview/logs.txt

for i in {1..100}
do
        p=".txt"
        x="$i$p"
        rm ~/mysecureview/log/$x
done

rmdir ~/mysecureview/log

echo "====================="  
echo "~Uninstall Successful"
echo "====================="

Ecco lo script effettivo che viene eseguito quando il computer viene riattivato:

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

rm ~/mysecureview/snapshot.jpg
rm ~/mysecureview/date.txt

# temporary storage for the most recent log entry.
date=$(date)
entry="$numPics $date"

logNum="$numPics.txt"
echo "$entry" > ~/mysecureview/log/$logNum

#store the index for next use.
echo "$numPics" > ~/mysecureview/num.txt

#compile each and every log entry .txt file into the logs.txt file.
bash compile.bash
