You stuffed your 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 or system installations. Xonsh shell, fish, zsh, osquery and so on.
If you like the idea of xxh click ⭐ on the repo and tweet.
| 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 are a prime focus. |
Hermetic. Deleting the ~/.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 blindfolded 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 or browsr on the remote host, just put its portable version as an entrypoint in the xxh-shell. |
Chameleon. Switching 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. |

[Search xxh shell on Github](https://github.com/search?q=xxh-shell&type=Repositories) or [Bitbucket](https://bitbucket.org/repo/all?name=xxh-shell) or [create your shell entrypoint](https://github.com/xxh/xxh-shell-example) to use another portable shell.
### Prerun plugins
[Prerun plugins](https://github.com/xxh/xxh/wiki#plugins) allow you to bring any portable tools, dotfiles, or aliases to your xxh session before running the shell.
Pinned plugins: **[core](https://github.com/xxh/xxh-plugin-prerun-core)** (xxh-sudo, xxh-screen, xxh-tmux), **[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)**, **[starship](https://github.com/izissise/xxh-plugin-prerun-starship)**. There is [cookiecutter template to create a 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):
```
…
```
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 xxh arguments to preserve the ability to use the minus sign for the original ssh arguments. This allows just replacing the first two letters in the `ssh` command to convert it to the `xxh` command. Also see the [discussion](https://github.com/xxh/xxh/issues/129).
### 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:
```
…
```
### 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 a 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 the 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';
