4. Check status

memcached status

5. Perform operations

memcached run --target example.com

6. View results

memcached results

7. Stop service

memcached stop ```_

Advanced Workflow

Automation Beispiel

```bash

!/bin/bash

Automated memcached 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..."

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

done < "$TARGETS_FILE"

Generate summary report

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