rmux is born

rmux should be able to run any command on one or more remote systems.

- detects current repository and rsyncs it to remote HOSTS
- runs command on remote hosts
- each host has its own tmux window
- all tmux windows are syncronized
- just type exit to return to your machine

As easy as "rmux df" to see free disk space on all HOSTS.

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+rmux
+====
+
+``rmux`` allows you to run your local project on multiple remote machines in
+parallel.
+
+The command names comes from remote-tmux as it allows multiplexing commands
+on multiple remote machines, synchronized.
+
+The original purpose was to allow testing local changes to a project on other
+platforms, like running tox on another distribution.
+
+![](docs/movie.gif)
+
+Usage
+-----
+
+```bash
+# run df locally
+rmux df
+
+# close tmux session
+exit
+
+# run df on two remote hosts, syncronized windows
+HOSTS="node1 node2" rmux df
+```
+
+If you fail to define the ``HOSTS`` variable the tool will default to localhost
+but it will still use its logic of doing a rsync and running commands using
+tmux and ssh.
+
+How it works
+------------
+
+``rmux`` will detect current project by looking for the ``.git`` folder
+it in current directory or its parents.  If it fails to find
+any ``.git`` folder, it will skip the rsync part.
+
+The script will not rsync ``.gitignored`` files but it will sync untracked
+files.
+
+The destination folder on remote machines is ``~/.cache/.rmux/<projectname>``
+which will also become default directory.
+
+The remote user is based on host names or your ssh configuration.
+
+Installation
+------------
+
+```bash
+pip install rmux
+```
+
+While ``rmux`` is currently only a pure bash script, I used pip wheel as a way
+to distribute it as it cross platform and easy to use. In addition, it allows
+me to easily upgrade it.
+
+If you prefer you can
+just download the shell script and add it to your path.

+* [tmux-xpanes](https://github.com/greymd/tmux-xpanes) - auto-window layout
+  for tmux, a current requirement for rmux. Still, it should be possible to
+  avoid using it if you have only one remote host, just make a feature request
+  and I can implement it.
+* [direnv](https://direnv.net/) - define environment variables specific to current directory. This can be very handy if you want to have different set of HOSTS
+  for each project and avoid mentioning them on the command line.
+* [rtox](https://pypi.org/project/rtox/) which allows running tox on remote
+  machines this being the original project. With rmux you will no longer need
+  rtox as you can just do `rmux tox` instead of `rtox`, the big difference
+  being that the session is not closed automatically and that you can now
+  run on multiple remote hosts instead of just one.
