- `viking machine exec` — Execute command on machines

### File Operations
- `viking file copy` — Copy files/directories to/from machines

### SSH Key Management
- `viking key add` — Add SSH key from file
- `viking key generate` — Generate new SSH key
- `viking key copy` — Copy public SSH key to clipboard

### Configuration
- `viking config show` — Show current config folder

### Utility

## Usage Examples
- "Add a new remote machine"
- "Execute command on all machines"
- "Copy file to remote machines"
- "Generate SSH key"
- "Connect to machine with TTY"

## Installation

```bash
go install github.com/d3witt/viking@latest
```

Or download pre-built binaries from: https://github.com/d3witt/viking/releases

## Examples

```bash
# Add a machine with multiple addresses
viking machine add --name deathstar --key starkey 168.112.216.50 root@61.22.128.69:3000 73.30.62.32:3001

# Add machine using SSH Agent (no key specified)
viking machine add --name deathstar 168.112.216.50 root@61.22.128.69:3000

# Execute command on all machines in parallel
viking machine exec deathstar echo 1234

# Execute command with TTY for interactive shell
viking machine exec --tty deathstar /bin/bash

# Copy file to all machines in parallel
viking file copy /tmp/file.txt deathstar:/tmp/

# Add SSH key from file
viking key add --name starkey --passphrase dart ./id_rsa_star

# Generate new SSH key
viking key generate --name starkey2

# Copy public key to clipboard
viking key copy starkey2

# Check config folder
viking config show

# Set custom config directory
export VIKING_CONFIG_DIR=/custom/path
