# crussh: a modern cssh replacement
Available via [radicle](https://radicle.xyz/) at: `rad:z3BhWhapyVBzzuBicAyCcmMhv1yEe`

## What are this?

For anyone who needs to administrate clusters of many machines,
[clusterssh](http://sourceforge.net/projects/clusterssh/) has long been a
fallback for when the rest of your automation tools aren't working.

crussh aims to be a simple replacement for cssh with the following improvements:

- Uses a single window to hold multiple terminals.
- Intelligently tiles terminals to fit available window size.
- Scrolls available terminals when they don't all fit in-window.
- Never resizes a terminal smaller than 80x24 characters.
- Uses GTK and the VTE widget to provide modern, anti-aliased terminals.

## Install

The install process is very simple on most distros:

* Install python3 and python3-gi.
* Clone and symlink to your bin dir:
```bash
git clone https://github.com/nergdron/crussh.git
ln -s $(pwd)/crussh/crussh.py ~/bin/crussh
```

Run ```crussh HOST [HOST ...]```

## Examples

Basic usage is covered via the builtin help, which you can get by running
```crussh -h```. This section covers some common use cases.

To connect to a list of hosts in a file:
```bash
crussh $(cat hostlist.txt)
```

To use a custom login name, public key, or other SSH client options:
```bash
crussh -l someuser -i ~/.ssh/myotherkey -- host [host ...]
```

To do something other than ssh, such as edit a bunch of files in parallel:
```bash
crussh -e nano *.txt
```

## Usage Tips

Doing a clustered paste isn't completely obvious. The following methods will
work, after making sure you're clicked into the text entry box at the bottom of
the window:

- middle click or shift-insert to paste the X11 selection buffer.
- control-shift-v to paste the GTK/GNOME clipboard.
