# vdn-tools

A collection of scripts for Virtual Didactic Network (VDN).

## Bash completion script

This script can complete the most commonly used commands in VDN like `vdn-ssh`, `vdn-start` or `vdn-scp`.

It can complete network and system names. Guest filenames can also be completed like the `scp` command.

### Locally

Source the `completion/vdn-completion.bash` file in your `.bashrc`:

```bash
. ~/path/to/completions/vdn-completion.bash
```

### Globally

Copy the `vdn-completion.bash` file in `/usr/local/share/bash-completion/completions/` and link all the commands:

```bash
cp completion/vdn-completion.bash /usr/local/share/bash-completion/completions/vdn
grep 'complete -F \w* [a-z-]*' -- completion/vdn-completion.bash | awk '{ print "/usr/local/share/bash-completion/completions/"$NF }' | xargs -I {} ln -s /usr/local/share/bash-completion/completions/vdn {}
```

## `vdn-rsync`

Copy files between the host and the guest system using *rsync*.

### With a script

Use the `bin/vdn-rsync` script to have a nice interface with *rsync*.

```bash
vdn-rsync -av src root@bigboss:
```

Add it to your path:

```bash
PATH="$PATH:~/path/to/vdn-tools/bin/"
```

### Without a script

Specify the `vdn-ssh` command with `rsync`.

```bash
rsync -av src -e vdn-ssh root@bigboss:
```
