Run batch script on startup macos - launchd

Im trying to add a LaunchDeamon on MacOS that is executed on startup.

I made a .sh script which works on direct execution. Its located at /usr/local/libexec/scripts/startup/ This is my script: startup.sh

#!bin/bash

# Check if deamon is running

if [ "$(ps -ef | grep -v grep | grep clamd | wc -l)" -le 0 ]


then


 #Start deamon
 /opt/homebrew/Cellar/clamav/0.104.2/sbin/clamd
 echo "clamd started"

else
 echo "clamd already running"

fi

Also made a launchd file to run it on startup that looks like this. Its located at /Library/LaunchDaemons/ com.startup.plist

<?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>EnvironmentVariables</key>
                <dict>
                        <key>PATH</key>
                        <string>/bin:/usr/bin:/usr/local/bin</string>
                </dict>
                <key>Label</key>
                <string>com.startup</string>
                <key>Program</key>
                <string>/usr/local/libexec/scripts/startup/startup.sh</string>
                <key>RunAtLoad</key>
                <true/>
                <key>KeepAlive</key>
                <true/>
                <key>StandardOutPath</key>
                <string>/tmp/startup-scripts.stdout</string>
                <key>StandardErrorPath</key>
                <string>/tmp/startup-scripts.stderr</string>
        </dict>
</plist>

Now I want to add it to the launchctl list.

sudo launchctl load -w /Library/LaunchDaemons/com.startup.plist

Im looking through the list with sudo launchctl list | grep com.startup and it does exist:

-   78  com.startup

Unfortunately when restarting the computer it is not running the script.. There is no output in any of the stdin/out/err files.

Any suggestions why its not running on startup?

Tell me, if I can provide more infos

Solution

  • I was able to get it running by putting #!/bin/sh to the first line of code. I was having it at line 2..

    Also I was deleting all the StandardPath's. They are apparantly only for LaunchAgents.

    The tool LaunchControl is a GUI for LaunchAgents/Deamons. There I was able to get a proper error message. Its installable via brew
