surge_add.sh

# Surge for Mac
function surge_add() {
	if [ "$1" == "--proxy" -o "$1" == "-p" -o "$1" == "--direct" -o "$1" == "-d" ]; then
		if [ "$(cat ~/.surge.conf | grep -c $2)" -eq 0 ]; then
			if [ "$1" == "--proxy" -o "$1" == "-p" ]; then
				sed -i '' -e '541i \
				DOMAIN-SUFFIX,'$2',Proxy' ~/.surge.conf;
			fi;
			if [ "$1" == "--direct" -o "$1" == "-d" ]; then
				sed -i '' -e '541i \
				DOMAIN-SUFFIX,'$2',DIRECT' ~/.surge.conf;
			fi;
			osascript -e 'tell application "Surge" to quit';
			osascript -e 'run application "/Applications/Surge.app/"';
		else
			echo '"'"$2"'"'' already exists.';
			cat ~/.surge.conf | grep $2;
		fi;
	else
		echo "usage: surge_add [--proxy|-p|--direct|-d] [URL].";
	fi
}

因为 ~/.surge.conf 必须以 FINAL,Proxy 结尾，所以会用 sed 把配置写在第 541 行，你可以和我一样用 # Custom 把第 540 行替换掉。
