Mac中创建守护进程（Daemon）

创建一个可以执行的脚本 hello.sh 

touch /Users/oslivan/test/hello.sh

chmod 755 /Users/oslivan/test/hello.sh

## hello.sh start

for((;;))

do

  echo "hello."

  sleep 3

done

## hello.sh end

创建一个 plist， 并通过 launchctl 加载

touch /Users/oslivan/Library/LaunchAgents/com.oslivan.test.hello.plist

## com.oslivan.test.hello.plist start

<?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.oslivan.test.hello</string>

		<key>ProgramArguments</key>

		<array>

			<string>/Users/oslivan/test/hello.sh</string>

		</array>

		<key>StandardOutPath</key>

		<string>/Users/oslivan/test/logfile.log</string>

		<key>StandardErrorPath</key>

		<string>/Users/oslivan/test/logfile_error.log</string>

		<key>RunAtLoad</key>

		<true/>

		<key>KeepAlive</key>

		<true/>

	</dict>

</plist>

## com.oslivan.test.hello.plist end

launchctl load /Users/oslivan/Library/LaunchAgents/com.oslivan.test.hello.plist
