You stuffed command shell with aliases, tools and colors but you lose it all when using ssh. The mission of xxh is to bring your favorite shell wherever you go through ssh without root access and system installations.

[xxh demo]
Portable. Preparing portable shells and plugins occurs locally and then xxh uploads the result to the host. No installations or root access on the host required. Security and host environment a prime focus. Hermetic. Deleting ~/.xxh directory from the remote host will make the remote environment function as if xxh was never there. By default your home is the .xxh directory and you can choose the hermetic level of your xxh session. Careful. No blindfold copying config files from local to remote host. Following privacy and repeatability practices the best way is to fork the xxh plugin or shell example and pack your configs into it.
Be open and fork-ready. Every xxh repo could be forked, customized and reused without waiting for a package management system, xxh release or any third party packages. Five shells are currently supported and more could be added by the community. Do more. The xxh packages are not only about shells. Any type of tool or code could be behind an entrypoint. If you want to run browsh on the remote host, just put its portable version as an entrypoint in the xxh-shell. Chameleon. Switching the shells is as easy as possible and you don't have to be locked in to one shell. Choose your current shell based on the task you want to solve: xxh anyhost +s xonsh for a python environment, osquery for simple querying, fish for modern features or time-tested zsh and bash for speed.

Pinned plugins: **[core](https://github.com/xxh/xxh-plugin-prerun-core)** (xxh-sudo, xxh-screen), **[dotfiles](https://github.com/xxh/xxh-plugin-prerun-dotfiles)**, **[docker](https://github.com/xxh/xxh-plugin-prerun-docker)**, **[python](https://github.com/xxh/xxh-plugin-prerun-python)**, **[xxh](https://github.com/xxh/xxh-plugin-prerun-xxh)**, **[vim](https://github.com/xxh/xxh-plugin-prerun-vim)**, **[zoxide](https://github.com/xxh/xxh-plugin-prerun-zoxide)**. There is [cookiecutter template to create prerun plugin](https://github.com/xxh/cookiecutter-xxh-plugin-prerun). ## Usage Use `xxh` instead of `ssh` when connecting to Linux hosts without changing ssh arguments: ``` xxh xxh [ssh arguments] [user@]host[:port] [xxh arguments] xxh local [xxh arguments] ``` Common examples (use `xxh --help` to get info about arguments): ```yaml xxh anyhost # Connect to the host xxh -i id_rsa -p 2222 anyhost # Using ssh arguments: port and key xxh anyhost +s zsh +i # Set the shell and install it without yes/no question xxh anyhost +s xonsh +hhh "~" # Set /home/user as home directory (read Q&A) xxh anyhost +s bash +I xxh-plugin-bash-vim # Preinstall a plugin xxh anyhost +if +q # Force reinstall xxh on the host in quiet mode xxh anyhost +hh /tmp/xxh +hhr # Upload xxh to /tmp/xxh and remove when disconnecting source xxh.zsh anyhost +I xxh-plugin-zsh-ohmyzsh # Connect in seamless mode with ohmyzsh plugin xxh local +s xonsh # Experimental: build xxh environment inplace and without ssh ``` For reusing arguments and simplifying xxh usage (like shortening to `xxh anyhost`) there is a [config file](https://github.com/xxh/xxh/wiki#config-file). **Why the plus sign for the xxh arguments?** The xxh is using the plus sign for the xxh arguments to save the ability to use minus sign for the original ssh arguments. This allows just replace the first two letters in the `ssh` command to convert it to the `xxh` command. ### Installing xxh packages ```bash xxh [+I xxh-package +I ...] [+L] [+RI xxh-package +RI ...] [+R xxh-package +R ...] ``` Different ways to set the xxh package source: ```yaml xxh +I xxh-shell-example # install from https://github.com/xxh xxh +I https://github.com/xxh/xxh-shell-example # short url for github only, for other sources use examples below or add support xxh +I https://github.com/xxh/xxh-shell-example/tree/mybranch # short url for github only, for other sources use examples below or add support xxh +I xxh-shell-example+git+https://github.com/xxh/xxh-shell-example # long url for any git repo xxh +I xxh-shell-example+git+https://github.com/xxh/xxh-shell-example/tree/mybranch # github only branch support xxh +I xxh-shell-example+git+git@github.com:githubuser/xxh-shell-example.git # install from private repository using ssh xxh +I xxh-shell-example+path+/home/user/my-xxh-dev/xxh-shell-example # install from local path ``` ### Using xxh inplace without ssh connection This is experimental magic. Please read the text below twice. If you have shell access on the host or you're in a docker container and you can't ssh to it then you can download and build hermetic xxh environment inplace. The `xxh local` command works exactly like `xxh remote_host` and creates a hermetic environment in `~/.xxh` by default. At this time we don't have portable build tools like `git`, `wget`, `curl`, `tar` and others which could be required by some xxh package build scripts. When running `xxh local` it is expected that the tools are present on the host. To run xxh inplace on Linux x86_64 just copy and paste these bash commands: ```bash XH=~/.xxh \ && XD=https://github.com/xxh/xxh-portable/raw/master/result/xxh-portable-musl-alpine-Linux-x86_64.tar.gz \ && mkdir -p $XH && cd $XH \ && ( [[ -x $(command -v curl) ]] && curl -L $XD || wget -O- $XD ) | tar zxf - xxh \ && echo 'Usage: ./xxh local [+s xonsh/zsh/fish/osquery/bash]' ``` Next time you're on host just run `~/.xxh/xxh local` and you will enter your xxh environment. ## Examples of use cases ### Python with pip everywhere without installation #### Way 1. Using xonsh ``` xxh anyhost +s xonsh anyhost> python --version Python 3.8.2 ``` You'll get python-powered [xonsh](https://xon.sh) shell with portable python and pip on the host without any system installations on the host. You can install PyPi packages manually or bring them with you automatically by using [xxh-plugin-prerun-dotfiles](https://github.com/xxh/xxh-plugin-prerun-dotfiles). Also don't forget about xxh-plugins like [zoxide](https://github.com/xxh/xxh-plugin-prerun-zoxide). #### Way 2. Using portable python on any xxh shell ``` xxh +RI xxh-plugin-prerun-python xxh anyhost +s zsh anyhost> python --version Python 3.8.2 anyhost> pip install pandas ``` Using [xxh-plugin-prerun-python](https://github.com/xxh/xxh-plugin-prerun-python) you'll get a portable Python AppImage which can be used on a host without python and with any xxh shell. ### Using docker on host without root access Try [xxh-plugin-prerun-docker](https://github.com/xxh/xxh-plugin-prerun-docker): ``` xxh +RI xxh-plugin-prerun-docker xxh anyhost +if anyhost> xxh-docker-run anyhost> docker ps CONTAINER ID IMAGE COMMAND anyhost> docker run --rm hello-world | grep Hello Hello from Docker! anyhost> xxh-docker-stop ``` ### Bring dotfiles to xxh session There is the [xxh-plugin-prerun-dotfiles](https://github.com/xxh/xxh-plugin-prerun-dotfiles) plugin which creates config files when you go to the host using xxh. You can fork it and create your cozy settings once and forever. ### Seamless Oh My Zsh ([demo](https://asciinema.org/a/rCiT9hXQ5IdwqOwg6rifyFZzb)) ```shell script source xxh.zsh anyhost +I xxh-plugin-zsh-ohmyzsh +if +q ``` This command brings your current Oh My Zsh session theme to the xxh session. If you need more complex settings just fork the [xxh-plugin-zsh-ohmyzsh](https://github.com/xxh/xxh-plugin-zsh-ohmyzsh) and hack it. ### Read host as a table with [osquery](https://github.com/xxh/xxh-shell-osquery) ``` $ xxh anyhost +s osquery osquery> SELECT * FROM users WHERE username='news'; +-----+-----+----------+-------------+-----------------+-------------------+ | uid | gid | username | description | directory | shell | +-----+-----+----------+-------------+-----------------+-------------------+ | 9 | 9 | news | news | /var/spool/news | /usr/sbin/nologin | +-----+-----+----------+-------------+-----------------+-------------------+ ``` ### All in one portable home xxh is very agile. You can create your own `xxh-shell` (the shell part means it has an entrypoint) which can have any portable tools that could help you on the host. [Bash](https://github.com/xxh/xxh-shell-bash) xxh-shell is one of these platforms that could be forked and stuffed. ## [Questions and answers](https://github.com/xxh/xxh/wiki) - [Welcome to xxh family](https://github.com/xxh/xxh/wiki#welcome-to-xxh-family) * [How it works](https://github.com/xxh/xxh/wiki#how-it-works) + [Simple answer](https://github.com/xxh/xxh/wiki#simple-answer) + [Detailed workflow with code](https://github.com/xxh/xxh/wiki#detailed-workflow-with-code) * [Plugins](https://github.com/xxh/xxh/wiki#plugins) * [Connection speed](https://github.com/xxh/xxh/wiki#connection-speed) * [Seamless mode](https://github.com/xxh/xxh/wiki#seamless-mode) * [Config file](https://github.com/xxh/xxh/wiki#config-file) - [Packages for xxh](https://github.com/xxh/xxh/wiki#packages-for-xxh) * [Install shells and plugins](https://github.com/xxh/xxh/wiki#install-shells-and-plugins) - [Advanced](https://github.com/xxh/xxh/wiki#advanced) * [How to set /home/user as home on host](https://github.com/xxh/xxh/wiki#how-to-set-homeuser-as-home-on-host) * [Using sudo](https://github.com/xxh/xxh/wiki#using-sudo) * [Using xxh in xxh session](https://github.com/xxh/xxh/wiki#using-xxh-in-xxh-session) * [Target host is behind another host](https://github.com/xxh/xxh/wiki#target-host-is-behind-another-host) * [Environment variables](https://github.com/xxh/xxh/wiki#environment-variables) - [Development and contribution](https://github.com/xxh/xxh/wiki#development-and-contribution) * [The easiest way to debug shell and plugins](https://github.com/xxh/xxh/wiki#the-easiest-way-to-debug-shell-and-plugins) * [Prerun plugins](https://github.com/xxh/xxh/wiki#prerun-plugins) * [Change plugin run order](https://github.com/xxh/xxh/wiki#change-plugin-run-order) - [New questions](https://github.com/xxh/xxh/wiki#new-questions) ## Development In the [xxh development environment](https://github.com/xxh/xxh/tree/master/xde) there is full [dockerised](https://www.docker.com/) environment for development, testing and contribution.

The main goal of teams is to create groups of passionate people who could help or support solving complex problems. Some people could be an expert in one shell and a newbie in another shell and mutual assistance is the key to xxh evolution.
