## Usage Examples

### Example 1: Single Command

```bash
# Simple command - no session needed
ssh_execute server="rock5t" command="df -h"
```

### Example 2: Multi-step Deployment with Session

```bash
# Check existing sessions first
ssh_session_list

# Start a persistent session
ssh_session_start server="rock5t" name="deploy"

# Get session ID from previous response
ssh_session_send session="xxx" command="cd /home/imax/project"
ssh_session_send session="xxx" command="git pull origin main"
ssh_session_send session="xxx" command="npm install"
ssh_session_send session="xxx" command="npm run build"
ssh_session_send session="xxx" command="pm2 restart all"

# Close when done
ssh_session_close session="xxx"
```

### Example 3: System Health Check

```bash
# Check overall health
ssh_health_check server="rock5t"

# Monitor specific resources
ssh_monitor server="rock5t" type="cpu" interval=5 duration=30

# Check specific services
ssh_service_status server="rock5t" services="nginx,docker,postgres"
```

### Example 4: File Deployment

```bash
# Upload deployment package
ssh_upload server="rock5t" localPath="./dist/app.tar.gz" remotePath="/tmp/app.tar.gz"

# Extract and restart
ssh_execute server="rock5t" command="cd /tmp && tar -xzf app.tar.gz && cp -r app/* /var/www/ && pm2 restart app"
```

### Example 5: Log Monitoring

```bash
# Tail real-time logs
ssh_tail server="rock5t" file="/var/log/nginx/access.log" lines=50 follow=true

# Filter with grep
ssh_tail server="rock5t" file="/var/log/syslog" grep="error" lines=100
```

### Example 6: Create SSH Tunnel

```bash
# Local port forward (access remote service locally)
ssh_tunnel_create server="rock5t" type="local" localPort=5432 remoteHost="localhost" remotePort=5432

# Now connect to local:5432 to access remote database
```

## Workdir Management

Store SSH operation results in `~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/` for reuse and comparison.

### Structure

```
~/.ssh-workdir/
└── {hostname}/
    └── {YYYY-MM-DD}-{topic}/
        ├── commands.md    # All executed commands
        ├── output/        # Command outputs
        │   ├── df-h.txt
        │   ├── cpu.txt
        │   └── memory.txt
        ├── status.json    # Host status snapshot
        └── summary.md     # Findings and notes
```

### Create Workdir

```bash
# Create new workdir
mkdir -p ~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/output

# Create commands log
touch ~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/commands.md
```

### Log Commands

```bash
# Add command to log
echo "## $(date)" >> ~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/commands.md
echo 'df -h' >> ~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/commands.md
```

### Save Output

```bash
# Execute and save
ssh_execute server="{hostname}" command="df -h" > ~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/output/df-h.txt
```

### Write Summary

```bash
# Write findings
echo '## System Check Findings' >> ~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/summary.md
echo '- Disk usage: 75% on /dev/sda1' >> ~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/summary.md
echo '- Memory: 4GB/16GB used' >> ~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/summary.md
```

### Reuse Previous Context

```bash
# Check if recent work exists
ls ~/.ssh-workdir/{hostname}/

# Read previous summary
cat ~/.ssh-workdir/{hostname}/{previous-date}-{topic}/summary.md

# Compare outputs
diff ~/.ssh-workdir/{hostname}/{yesterday}-{topic}/output/df-h.txt \
     ~/.ssh-workdir/{hostname}/{today}-{topic}/output/df-h.txt
```

## Session Management Guidelines

### When to Use Sessions

**Use session for:**
- Multi-step deployments
- Tasks requiring state (cd, environment)
- Long-running workflows (more than 3 commands)
- Tasks where command order matters

**Don't use session for:**
- Single quick commands (`df -h`, `pwd`)
- Unrelated commands that don't need state
- Read-only monitoring tasks

### Session Lifecycle

```bash
# 1. Check existing sessions first
ssh_session_list

# 2. Reuse existing session if available and still active
ssh_session_send session="existing-id" command="..."

# 3. Start new session only if necessary
ssh_session_start server="{hostname}" name="{task-name}"

# 4. ALWAYS close when done
ssh_session_close session="{session-id}"
```

### Timeout Considerations

- SSH server may close idle sessions (typically 3-5 minutes by default)
- Configure `ClientAliveInterval` on server for longer keepalive
- For long-running tasks, consider periodic lightweight commands to keepalive
- If session becomes unresponsive, create a new one

## Best Practices

### Before SSH Operations

1. **Check existing sessions**
   ```bash
   ssh_session_list
   ```

2. **Check recent workdir**
   ```bash
   ls ~/.ssh-workdir/{hostname}/
   ```

3. **Create new workdir if starting new task**
   ```bash
   mkdir -p ~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/output
   ```

### During SSH Operations

1. **Use appropriate tool for the task**
   - Single command: `ssh_execute`
   - Multi-step: `ssh_session_start` → `ssh_session_send` → `ssh_session_close`
   - File transfer: `ssh_upload/download/sync`
   - Monitoring: `ssh_monitor`, `ssh_tail`, `ssh_health_check`

2. **Log commands to workdir**
   ```bash
   echo "command" >> ~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/commands.md
   ```

3. **Save important outputs**
   ```bash
   ssh_execute server="{hostname}" command="df -h" > ~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/output/df-h.txt
   ```

### After SSH Operations

1. **Close sessions**
   ```bash
   ssh_session_close session="{session-id}"
   ```

2. **Write summary**
   ```bash
   echo '## Findings' >> ~/.ssh-workdir/{hostname}/{YYYY-MM-DD}-{topic}/summary.md
   ```

3. **Clean up**
   - Close tunnels: `ssh_tunnel_close`
   - Verify all sessions closed: `ssh_session_list`

## Tips

- Use `ssh_session_list` before starting new tasks to reuse existing sessions
- Create workdir for each task to maintain organized history
- Write summaries to quickly recall previous work
- Use `ssh_connection_status action="status"` to check connection health
- For server comparison, store outputs with consistent naming across hosts
- Close sessions when done to free resources
- Configure server-side `ClientAliveInterval` for longer session timeouts if needed
