<palign="center">You chosen a command shell and spent months to stuffed it with shortcuts and colors. But when you move from local to remote host using ssh you lose it all. The mission of xxh is to bring your favorite shell wherever you go through the ssh.</p>
To use seamless mode run `./xxh ++extract-sourcing-files` to extract `xxh.*sh` files to the current directory then run `source xxh.zsh myhost` command for seamless connecting.
[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-sample) to use another portable shell.
xxh -i id_rsa -p 2222 myhost # connect using key and port
xxh myhost +s zsh # connect to the host into zsh shell
source xxh.zsh myhost +I xxh-plugin-zsh-ohmyzsh # install zsh plugin then connect into zsh with seamless mode (zsh theme name will be add from local host)
**Portable**. By default building occurs locally and then xxh uploads the result to host. No installations or root access on the host required. The security and careful about environment on the host are behind it.
**Careful**. No blindfold copying config files from local to remote host. The privacy and repeatability reasons are behind it. Every xxh package, shell or plugin is the bridge that use only what required, no more.
**Hermetic**. If you delete `~/.xxh` directory from the remote host then xxh has never been on the host. If files appears outside xxh home directory feel free to report about this cases.
**Fork-ready**. Every repo could be forked, customized and used without waiting of package management system, xxh releases or any third party.
**Do more**. The xxh packages are not only about shells. Any type of tool or code could be behind "shell entrypoint". If you want to play Super Mario on the remote host just put it as entrypoint.
**Be open**. Currently supported five shells and the count could be grow by community.
When you run `xxh myhost` command xxh download portable shell and store locally to future use. Then if it needed xxh upload the portable shell, init scripts and plugins to the host. Finally xxh make ssh connection to the host and run portable shell without any system installs, root access and affection on the target host.
The first connection takes time for downloading and uploading portable shell. It depends on portable shell size and channel speed. But when xxh is installed on the host and you do just `xxh myhost` then it works as ordinary ssh connection speed plus speed of initializing the shell you used. You could monitor all process using `+vv` argument.
Add `ProxyCommand` or `ProxyJump` to your ssh config [as described](https://superuser.com/questions/96489/an-ssh-tunnel-via-multiple-hops#answer-170592) and then do ordinary `xxh host_internal`.
It is the set of scripts which will be run on the host when you go using xxh. It could be shell settings, aliases, environment variables, frameworks, extensions, color themes and everything you need. You can find the links to plugins on [xxh-shells repos](https://github.com/search?q=xxh%2Fxxh-shell&type=Repositories). Feel free to fork it.
When you run `xxh myhost +s xonsh-appimage` you'll get portable python, pip and python-powered shell on the host without any system installations on the host. Add plugins: [autojump](https://github.com/xxh/xxh-plugin-xonsh-autojump) saves time, [pipeliner](https://github.com/xxh/xxh-plugin-xonsh-pipe-liner) manipulates lines and [bar](https://github.com/xxh/xxh-plugin-xonsh-theme-bar) looks nice.
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.
The xxh is very agile. You can create your own `xxh-shell` (shell word means it has entrypoint) which has any portable tools
that you could help you on the host. [Bash-zero](https://github.com/xxh/xxh-shell-bash-zero) xxh-shell is one of this platforms that could be forked and stuffed.
In the [xxh-dev](https://github.com/xxh/xxh-dev) repo there is full [docker](https://www.docker.com/)ised environment for development, testing and contribution. The process of testing and development is orchestrated by `xde` tool and as easy as possible.
**We have teams.** If you're in team it does not oblige to do something. The main goal of teams is to create group of passionate people who could help or support in complex questions. Some people could be expert in one shell and newbie in another shell and mutual assistance is the key to xxh evolution. [Ask join.](https://github.com/xxh/xxh/issues/50)
