# Erste Schritte mit Amazon S3 unter Verwendung der CLI
<a name="s3_example_s3_GettingStarted_section"></a>

Wie das aussehen kann, sehen Sie am nachfolgenden Beispielcode:
+ Erstellen Sie einen S3-Bucket mit eindeutiger Benennung und regionaler Konfiguration.
+ Konfigurieren Sie die Bucket-Sicherheitseinstellungen, einschließlich der Blockierung des öffentlichen Zugriffs.
+ Aktivieren Sie die Versionsverwaltung und Standardverschlüsselung für den Datenschutz.
+ Laden Sie Objekte mit und ohne benutzerdefinierte Metadaten hoch.
+ Laden Sie Objekte aus dem Bucket in den lokalen Speicher herunter.
+ Kopieren Sie Objekte innerhalb des Buckets, um Daten in Ordnern zu organisieren.
+ Listen Sie Bucket-Inhalte und Objekte mit bestimmten Präfixen auf.
+ Fügen Sie Tags zu Buckets für die Ressourcenverwaltung hinzu.
+ Bereinigen Sie alle Ressourcen einschließlich versionierter Objekte.

**AWS CLI mit Bash-Skript**  
 Es gibt noch mehr dazu. GitHub Hier finden Sie das vollständige Beispiel und erfahren, wie Sie es im [Tutorials und Beispiele](https://github.com/aws-samples/sample-developer-tutorials/tree/main/tuts/003-s3-gettingstarted)-Repository für Entwickler einrichten und ausführen.

# Amazon S3 Getting Started Tutorial Script
# This script demonstrates basic S3 operations including:
# - Creating a bucket
# - Configuring bucket settings
# - Uploading, downloading, and copying objects
# - Deleting objects and buckets

# Latest fixes:
# 1. Fixed folder creation using temporary file
# 2. Corrected versioned object deletion in cleanup
# 3. Improved error handling for cleanup operations

# Set up error handling
