vmess-url-outbound-to-given-v2ray-config-json-file.sh

#!/usr/bin/env bash
set -euo pipefail

vmess_file_path=$1
config_file_path=$2
vmess_line=$3

line=`sed -n ${vmess_line}p $vmess_file_path`
result=`v2ray-tools vmess2config --port 8080 --url $line`
outbound=`echo $result | jq '.outbounds[0]'`
new_content=`cat "/etc/v2ray/config.json" | jq -r ".outbounds[0]=$outbound"`

sudo bash -c "echo '$new_content' > $config_file_path"

# change file config.json and restart v2ray.service
sudo systemctl restart v2ray.service
sudo systemctl status v2ray.service | sed -n 3p

# usage example: 
# bash /home/wd/Documents/vmess/vmess.info /etc/v2ray/config.json 20
#
# requirements:
# 1. npm -g install v2ray-tools
# 2. vmess.info, ie. vmess url list in a file named "vmess.info"
#
# notifications:
# 1. it's will not help you to create /etc/v2ray/config.json, you need a available config.json with replaceable outbounds
# 2. backup your config.json first
#
# todo:
# 1. also we can change the line number with vmess url
