Launch daemon worked as it should but now the problem is it keeps loading the same shell script and I can see multiple entries for the same rule. sudo ipfw list. How can this be prevented?

Use LaunchOnlyOnce key in plist file.
LaunchOnlyOnce :
This optional key specifies whether the job can only be run once and only once. In other words, if the
job cannot be safely respawned without a full machine reboot, then set this key to be true.

I'm trying to write a Launchd script to execute a simple sh script that will 1) launch mopidy 2) mkfifo /tmp/mopidy.fifo 3) pass data from port 5555 into this file using socat.
I've tried setting up a mopidy.plist LaunchAgent that executes a mopidy.sh script file at login. I've verified that the LaunchAgent gets started correctly and that the script has execution permissions. I've also tried the Program Arguments approach by passing the script as a one-liner to /bin/bash, but when I try that I get errors logged saying that its unable to find socat.
mopidy.sh
nohup mopidy;
mkfifo /tmp/mopidy.fifo;
while :; do
socat -d -d -T 1 -u UDP4-LISTEN:5555 OPEN:/tmp/mopidy.fifo;
done
mopidy.plist
<!-- Starts mopidy server -->

I am able to execute the bash script normally without error from the command line, however it doesn't seem like the service is able to because the /tmp/modipy.fifo file never gets created and the listener is never made. The logfile and error_logfile are never populated either.
I was able to get it working by including environment variables. I don't fully understand this, but everything works now with the following:
<!-- Starts mopidy server -->

Here is my file, I am not getting anything logged, although the loading is apparently successful, as I can see it running with the list command;

I am also not clear if I need to running 'start' after load, or does that happen automatically since I have the 'RunAtLoad' key set to true? I have tried calling start after load, and not with no luck.
This plist file is in the /Library/LaunchAgents directory and I am calling with load and unload with sudo.
The sh file was not executable.
chmod +x getData.sh
did the trick.
I'm current trying to set up my program as a scheduled task in OSX. I tried setting up a plist file for launchd after compiling with the mix using escript.build.
However, OSX simply ignores running my program even though launchd says it's "Loaded".
If I try to execute the program in a terminal it runs fine. Here is what my plist file looks like
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

I want to rsync my /var/repo backup to a remote machine when it changes.
I made a ssh key pairs to make my machine can ssh login to remote without password(ignore details).
I added a file com.ph.rsync2.plist in ~/Library/LaunchAgents.
The content is
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.ph.rsync2.plist</string>
<key>ProgramArguments</key>
<array>
<string>/usr/bin/rsync</string>
<string>-avz</string>
<string>--rsh=ssh</string>
<string>/var/repo</string>
<string>flora#192.168.19.28:/var/ph_backups/</string>
</array>
<key>WatchPaths</key>
<array>
<string>/var/repo</string>
</array>
</dict>
Then I launchctl load com.ph.rysnc2.plist.
When /var/repo has any change, it will trigger rsync to work
but I always get the error log in Console.app
It reads like
11/3/15 2:15:26.399 PM com.apple.xpc.launchd[1]:
(com.ph.rsync2.plist) Service only ran for 1 seconds. Pushing respawn out by 9 seconds.
And I tried to move the rsync commands to a script, then let launchd exec my script. but it's still the same
I can't figure out which part of settings make all these fail.
Anyone can give me a clue?
Comments will mess up the formatting, so I'll post how to setup the StandardErrorPath key as an answer.
Modify your job definition like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.ph.rsync2.plist</string>
<key>ProgramArguments</key>
<array>
<string>/usr/bin/rsync</string>
<string>-avz</string>
<string>--rsh=ssh</string>
<string>/var/repo</string>
<string>flora#192.168.19.28:/var/ph_backups/</string>
</array>
<key>StandardErrorPath</key>
<string>/tmp/com.ph.rsync2.plist.stderr</string>
<key>WatchPaths</key>
<array>
<string>/var/repo</string>
</array>
</dict>
</plist>
Check the file /tmp/com.ph.rsync2.plist.stderr after reloading and starting the job.
I need to run an mac app daily without any user interaction using launchd, i created a .plist file and pasted it in /system/LaunchDaemons and after that how to execute the plist file, can any one please tell me the step by step working process on how to work with launchd it will helpful for me, I pasted my .plist file below.

You'll probably need the name of your program like this rather than ProgramArguments:
<key>Program</key>
<string>/Applications/myapp.app/Contents/MacOS/myapp</string>
