MacOS X LionのFTPサーバを起動したり停止たりするスクリプト

Lionになってからシステム環境設定でFTPサーバのON・OFFができなくなったので。

ftp-server.sh

# !/bin/bash

show_brief() {
	echo "A FTP server manager."
}

	name=$(basename $0)
	show_brief

	echo "    $name status    : Show FTP server status."
}

	running=0
	sudo launchctl list com.apple.ftpd > /dev/null 2>&1 && running=1
	return $running
}

start_ftp_server() {
	is_ftp_server_running
	if [ $? -eq 1 ]
	then
		echo "FTP server is already started."

	fi

	sudo launchctl load -w /System/Library/LaunchDaemons/ftp.plist
	echo "Start FTP server [OK]"
}
