V2Ray Proxy Manager

A Bash script to configure system-wide proxy settings for V2Ray on Linux. Supports separate HTTP and SOCKS5 proxies, auto-detects V2Ray ports from its config, and writes settings to both /etc/profile.d/proxy.sh and /etc/environment for maximum compatibility.

Features

• V2Ray port auto-detection — reads http and socks inbound ports from /usr/local/share/v2ray/config.json (falls back to 10809/10808)
• Separate HTTP and SOCKS5 proxy configuration
• Port reachability test before applying settings
• Dual-file writes — /etc/profile.d/proxy.sh (login shells) and /etc/environment (display managers / PAM)
• Safe backups — timestamped .bak files created before any modification
• HTB-aware no_proxy — bypasses *.htb and *.local out of the box
• Electron/Chromium compatibility flag included
• Colored output for clear status feedback

Prerequisites

• Linux (Debian/Ubuntu/Arch or any distro with /etc/environment)
• bash
• jq (for V2Ray config parsing)
• Root privileges (sudo or run as root)

Installation

# Copy to system PATH
sudo cp proxy.sh /usr/local/bin/proxy
sudo chmod +x /usr/local/bin/proxy

Usage

sudo proxy

Menu Options

Choice	Action
1	Custom — prompts for HTTP IP/port and SOCKS5 IP/port
2	Default — auto-detects V2Ray ports and applies immediately
3	Unset — removes all proxy settings from both files and current shell

Apply to Running Terminals

After setting, existing terminals need a manual source:

source /etc/profile.d/proxy.sh

New login sessions pick up settings automatically.

Files Modified

File	Purpose
/etc/profile.d/proxy.sh	Loaded by login shells (export statements)
/etc/environment	Loaded by PAM / display managers (no export)
