gg (go-graft)

English
中文简体

gg is a command-line tool for one-click proxy in your research and development.

You can just add gg before another command to redirect its traffic to your proxy without installing v2ray or anything else. Usage example: gg python -m pip install torch.

It was inspired by graftcp, is a pure golang implementation with more useful features.

Why did I create go-graft?

I am so tired of the poor network condition in my research and development. But I do not want to install v2ray in the working servers because it is too heavy.

Thus, I need a light and portable command-line tool to help me download and install dependencies and software on various servers.

Advantages

Compared to proxychains or graftcp, we have the following advantages:

Use it independently without any other proxy utils.
UDP support.
Support golang programs. See applications built by Go can not be hook by proxychains-ng .

Installation

Run this command to download the latest release of go-graft:

# curl -Ls https://github.com/mzz2017/gg/raw/main/release/go.sh | sudo sh
# use the mirror:
curl -Ls https://hubmirror.v2raya.org/raw/mzz2017/gg/main/release/go.sh | sudo sh

If the command gg fails after installation, check your path.

You can also create a symbolic link to /usr/bin or any other directory in your path.

For example:
sudo ln -s /usr/local/bin/gg /usr/bin/gg

Test the installation.
```
$ gg --version
gg version 0.1.1
```

Usage

Examples:

Configure the subscription:

gg config -w subscription=https://example.com/path/to/sub

Test with cloning linux repo:

gg git clone --depth=1 https://github.com/torvalds/linux.git

Output:

Cloning into 'linux'...
...
Receiving objects: 100% (78822/78822), 212.19 MiB | 7.04 MiB/s, done.
Resolving deltas: 100% (7155/7155), done.

Or just redirect the traffic of whole shell session to your proxy:

gg bash

git clone --depth=1 https://github.com/torvalds/linux.git
curl ipv4.appspot.com

Temporarily use

Use share-link

# if no configuration was written before, a share-link will be required to input.
gg wget -O frp.tar.gz https://github.com/fatedier/frp/releases/download/v0.38.0/frp_0.38.0_linux_amd64.tar.gz

Enter the share-link of your proxy: ********

Saving to: ‘frp.tar.gz’

Or use --node:

gg --node ss://YWVzLTEyOC1nY206MQ@example.com:17247 speedtest

Use subscription

By default, gg will automatically select the first available node from the subscription:

gg --subscription https://example.com/path/to/sub docker pull caddy

Long-term use

Write a config variable with -w:

Set subscription:

gg config -w subscription=https://example.com/path/to/sub
gg curl ipv4.appspot.com

13.141.150.163

Set node:

gg config -w node=vmess://MY_VMESS_SERVER_SHARE_LINK
gg curl ipv4.appspot.com

53.141.112.10

List config variables:

gg config

node=
subscription.link=https://example.com/path/to/sub
subscription.select=first
subscription.cache_last_node=true
cache.subscription.last_node=trojan-go://MY_TROJAN_GO_SERVER_SHARE_LINK
no_udp=false
test_node_before_use=true

Read specific config variable:

gg config node

vmess://MY_VMESS_SERVER_SHARE_LINK

Q&A

Q: When I use sudo gg xxx, it remains to ask me for share-link even though config has been set. How to solve it?

A: Use sudo -E gg xxx to solve it.
Q: Can I use it on my IPv6-only machine?

A: Of course, as long as your proxy server has an IPv6 entry.
Q: When I use gg sudo xxx, I get sudo: effective uid is not 0, ..., how can I fix it?

A: You should run sudo gg xxx instead, because setuid and ptrace can not work together. See stackoverflow.

Shell autocompletion

If you want to complete other commands while using gg, please follow the method below:

bash

Add this line to ~/.bashrc:

complete -F _command gg

zsh

Add this line to ~/.zshrc:

compdef _precommand gg

If you get an error like complete:13: command not found: compdef, add following content in the beginning of the .zshrc file.

autoload -Uz compinit
compinit

fish

Write following content in ~/.config/fish/completions/gg.fish:

# fish completion for gg

function __fish_gg_print_remaining_args
    set -l tokens (commandline -opc) (commandline -ct)
    set -e tokens[1]
    if test -n "$argv"
        and not string match -qr '^-' $argv[1]
        string join0 -- $argv
        return 0
    else
        return 1
    end
end

function __fish_complete_gg_subcommand
    set -l args (__fish_gg_print_remaining_args | string split0)
    __fish_complete_subcommand --commandline $args
end

# Complete the command we are executed under gg
complete -c gg -x -a "(__fish_complete_gg_subcommand)"
