launchctl

Below outlines an example for MacOS users using launchctl. launchctl will ensure switchboard is started and left running in the background, so you can get on with what you need to do.

Create the following file sudo touch /Library/LaunchDaemons/switchboard.plist and copy and paste the contents below. Note, you should make any changes necessary to the arguments list, depending on how you want to use the tool.

<?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">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>switchboard</string>
    <key>ServiceDescription</key>
    <string>File system watcher</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/local/bin/switchboard</string>
        <string>watch</string>
        <string>--config</string>
        <string>/path_to_your_config_file/config.yaml</string>
    </array>
    <key>RunAtLoad</key>
    <false/>
</dict>
</plist>

Then, run the following commands to load, start, and list the running service and ensuring it has started.

sudo launchctl load /Library/LaunchDaemons/switchboard.plist
sudo launchctl start switchboard

sudo launchctl list | grep switchboard
