needle init

2. Configure basic settings

needle config set host example.com needle config set port 8080

3. Start service

needle start

4. Check status

needle status

5. Perform operations

needle run --target example.com

6. View results

needle results

7. Stop service

needle stop ```_

Advanced Workflow

```bash

Comprehensive operation with monitoring

needle run \ --config production.yaml \ --parallel \ --workers 8 \ --verbose \ --timeout 300 \ --output json \ --log-file operation.log

Monitor in real-time

needle monitor --real-time --interval 5

Automation Beispiel

```bash

!/bin/bash

Automated needle workflow

Configuration

TARGETS_FILE="targets.txt" RESULTS_DIR="results/$(date +%Y-%m-%d)" CONFIG_FILE="automation.yaml"

Create results directory

mkdir -p "$RESULTS_DIR"

Process each target

while IFS= read -r target; do echo "Processing $target..."

needle \
    --config "$CONFIG_FILE" \
    --output json \
    --output-file "$RESULTS_DIR/$\\\\{target\\\\}.json" \
    run "$target"

done < "$TARGETS_FILE"

Generate summary report

needle report summary \ --input "\(RESULTS_DIR/*.json" \ --output "\)RESULTS_DIR/summary.html" ```_
