Beispiele

Basis-Workflow

```bash

1. Initialize linenum

linenum init

2. Configure basic settings

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

3. Start service

linenum start

4. Check status

linenum status

5. Perform operations

linenum run --target example.com

6. View results

linenum results

7. Stop service

linenum stop ```_

Advanced Workflow

```bash

Comprehensive operation with monitoring

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

Monitor in real-time

linenum monitor --real-time --interval 5

Generate report

linenum report --type comprehensive --output report.html ```_

Automation Beispiel

```bash

!/bin/bash

Automated linenum 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..."

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

done < "$TARGETS_FILE"

Generate summary report

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