====== Welche Linux-Distribution verwende ich? ======

Es gibt verschiedene Methoden, um herauszufinden, welche Linux-Distribution und Version auf einem System installiert ist. Diese Seite zeigt die gängigsten Wege zur Identifikation.

===== Schnellübersicht =====

<code bash>
# Einfachste Methode - funktioniert auf allen modernen Distributionen
cat /etc/os-release

# Alternative mit hostnamectl (systemd-Systeme)
hostnamectl

# LSB-Informationen (falls installiert)
lsb_release -a

# Kernel-Version
uname -a
</code>

===== Methode 1: /etc/os-release (Universal) =====

Die Datei ''/etc/os-release'' ist der moderne Standard und funktioniert auf nahezu allen aktuellen Distributionen.

==== Syntax ====

<code bash>
cat /etc/os-release
</code>

==== Beispiele für verschiedene Distributionen ====

</code>

===== Methode 2: hostnamectl (systemd) =====

Auf Systemen mit systemd liefert ''hostnamectl'' übersichtliche Systeminformationen.

==== Syntax ====

<code bash>
hostnamectl
</code>

==== Beispiel-Ausgabe ====

=== Debian ===
<code>
   Static hostname: debian-server
         Icon name: computer-vm
           Chassis: vm

</code>

===== Methode 3: lsb_release =====

Das ''lsb_release''-Kommando zeigt LSB (Linux Standard Base) Informationen an. Muss oft erst installiert werden.

==== Installation ====

<code bash>
# Debian / Ubuntu / Linux Mint
sudo apt install lsb-release

# Fedora
sudo dnf install redhat-lsb-core

# openSUSE / SUSE
sudo zypper install lsb-release
</code>

==== Syntax ====

<code bash>
lsb_release -a           # Alle Informationen
lsb_release -d           # Nur Beschreibung
lsb_release -i           # Nur Distributor ID
lsb_release -r           # Nur Release-Nummer
lsb_release -c           # Nur Codename
</code>

==== Beispiel-Ausgaben ====

=== Debian ===
<code>
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 12 (bookworm)
Release:        12
Codename:       bookworm
</code>

=== Ubuntu ===
<code>
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.3 LTS
Release:        22.04
Codename:       jammy
</code>

<code>
LSB Version:    :core-4.1-amd64:core-4.1-noarch
Distributor ID: Fedora
Description:    Fedora release 39 (Thirty Nine)
Release:        39
Codename:       ThirtyNine
</code>

===== Methode 4: Distributionsspezifische Dateien =====

Ältere Methode - verschiedene Distributionen nutzen unterschiedliche Dateien.

==== Alle Release-Dateien anzeigen ====

<code bash>
cat /etc/*release
# oder
cat /etc/*-release

# Liste aller Release-Dateien
ls -la /etc/*release /etc/*-release /etc/*_version 2>/dev/null
</code>

==== Distributionsspezifische Dateien ====

^ Distribution ^ Datei ^ Inhalt ^
| Debian | ''/etc/debian_version'' | ''12.4'' |
| Ubuntu | ''/etc/lsb-release'' | LSB-Informationen |
| Fedora | ''/etc/fedora-release'' | ''Fedora release 39 (Thirty Nine)'' |
| Red Hat | ''/etc/redhat-release'' | ''Red Hat Enterprise Linux release 9.3'' |
| SUSE | ''/etc/SuSE-release'' | Veraltet, nutze /etc/os-release |
| openSUSE | ''/etc/os-release'' | Standard-Datei |

==== Beispiele ====

=== Debian ===
<code bash>
cat /etc/debian_version
# Ausgabe: 12.4
</code>

=== Ubuntu (lsb-release) ===
<code bash>
cat /etc/lsb-release
</code>
<code>
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=22.04
DISTRIB_CODENAME=jammy
DISTRIB_DESCRIPTION="Ubuntu 22.04.3 LTS"
</code>

=== Fedora ===
<code bash>
cat /etc/fedora-release
# Ausgabe: Fedora release 39 (Thirty Nine)

cat /etc/redhat-release
# Ausgabe: Fedora release 39 (Thirty Nine)
</code>

=== Red Hat Enterprise Linux / CentOS / Rocky / Alma ===
<code bash>
cat /etc/redhat-release
# RHEL:   Red Hat Enterprise Linux release 9.3 (Plow)
# CentOS: CentOS Stream release 9
# Rocky:  Rocky Linux release 9.3 (Blue Onyx)
# Alma:   AlmaLinux release 9.3 (Shamrock Pampas Cat)
</code>

===== Methode 5: Kernel und System-Informationen =====

==== uname - Kernel-Informationen ====

<code bash>
uname -a                 # Alle Informationen
uname -r                 # Kernel-Version
uname -m                 # Architektur
uname -o                 # Betriebssystem
</code>

**Beispiel-Ausgaben:**

<code>
# Debian
Linux debian 6.1.0-13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.55-1 (2023-09-29) x86_64 GNU/Linux

# Ubuntu
Linux ubuntu 5.15.0-91-generic #101-Ubuntu SMP Tue Nov 14 13:30:08 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

# Fedora
Linux fedora 6.6.7-200.fc39.x86_64 #1 SMP PREEMPT_DYNAMIC Thu Dec 14 19:04:11 UTC 2023 x86_64 GNU/Linux

# openSUSE
Linux opensuse 5.14.21-150500.55.39-default #1 SMP PREEMPT_DYNAMIC Mon Dec 4 10:38:00 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
</code>

==== Weitere Systeminformationen ====

<code bash>
# Detaillierte Hardware-Infos
hostnamectl

# Prozessor
cat /proc/cpuinfo | grep "model name" | head -1

# Speicher
free -h

# Festplatten
lsblk
df -h
</code>

===== Methode 6: Paketmanager identifizieren =====

Die Art des Paketmanagers gibt Hinweise auf die Distribution.

<code bash>
# Debian/Ubuntu/Mint verwenden apt/dpkg
which apt
which dpkg

# Fedora/RHEL/CentOS verwenden dnf/yum/rpm
which dnf
which yum
which rpm

# SUSE/openSUSE verwenden zypper/rpm
which zypper

# Arch Linux verwendet pacman
which pacman
</code>

**Schnelltest:**
<code bash>
if [ -f /etc/debian_version ]; then
    echo "Debian-basiert"
elif [ -f /etc/fedora-release ]; then
    echo "Fedora"
elif [ -f /etc/redhat-release ]; then
    echo "Red Hat basiert"
elif [ -f /etc/SuSE-release ] || [ -f /etc/SUSE-brand ]; then
    echo "SUSE-basiert"
elif [ -f /etc/arch-release ]; then
    echo "Arch Linux"
fi
</code>

===== Praktische Skripte =====

==== Alle Methoden kombiniert ====

<code bash>
#!/bin/bash
# Distribution und Version anzeigen

echo "=== /etc/os-release ==="
if [ -f /etc/os-release ]; then
    source /etc/os-release
    echo "Name: $NAME"
    echo "Version: $VERSION"
    echo "ID: $ID"
    echo "Pretty Name: $PRETTY_NAME"
fi

echo ""
echo "=== hostnamectl ==="
if command -v hostnamectl >/dev/null 2>&1; then
    hostnamectl | grep "Operating System"
fi

echo ""
echo "=== lsb_release ==="
if command -v lsb_release >/dev/null 2>&1; then
    lsb_release -d
fi

echo ""
echo "=== uname ==="
uname -a

echo ""
echo "=== Kernel ==="
uname -r
</code>

==== Distribution in Variable speichern ====

<code bash>
#!/bin/bash
# Distribution ermitteln und speichern

if [ -f /etc/os-release ]; then
    source /etc/os-release
    DISTRO=$ID
    DISTRO_VERSION=$VERSION_ID
    echo "Distribution: $DISTRO"
    echo "Version: $DISTRO_VERSION"
    
    # Distributionsspezifische Aktionen
    case $DISTRO in
        debian|ubuntu|linuxmint)
            echo "Debian-basiertes System erkannt"
            PKG_MANAGER="apt"
            ;;
        fedora|rhel|centos|rocky|almalinux)
            echo "Red Hat-basiertes System erkannt"
            PKG_MANAGER="dnf"
            ;;
        opensuse*|sles)
            echo "SUSE-basiertes System erkannt"
            PKG_MANAGER="zypper"
            ;;
        arch|manjaro)
            echo "Arch-basiertes System erkannt"
            PKG_MANAGER="pacman"
            ;;
        *)
            echo "Unbekannte Distribution"
            ;;
    esac
    
    echo "Paketmanager: $PKG_MANAGER"
fi

===== Häufige Fragen =====

==== Warum mehrere Methoden? ====

  * Ältere Systeme haben oft nicht ''/etc/os-release''
  * Verschiedene Tools für verschiedene Zwecke
  * Kompatibilität mit Skripten und Automatisierung
  * Unterschiedliche Detailstufen

==== Welche Methode ist die beste? ====

**Empfehlung:**
  - **Modern**: ''cat /etc/os-release'' oder ''hostnamectl''
  - **Universell**: ''cat /etc/os-release'' funktioniert fast überall
  - **Detailliert**: ''hostnamectl'' auf systemd-Systemen
  - **Skripte**: ''/etc/os-release'' parsen

==== Was ist der Unterschied zwischen ID und ID_LIKE? ====

<code bash>
source /etc/os-release
echo "ID: $ID"           # Spezifische Distribution (z.B. "ubuntu")
echo "ID_LIKE: $ID_LIKE" # Basis-Distribution (z.B. "debian")
</code>

**ID_LIKE** ist nützlich für Skripte, die mehrere verwandte Distributionen unterstützen sollen.

===== Troubleshooting =====

==== Datei /etc/os-release fehlt ====

<code bash>
# Sehr alte Distribution - alternative Methoden nutzen:
cat /etc/*-release
cat /etc/*_version
lsb_release -a
uname -a
</code>

==== lsb_release nicht gefunden ====

<code bash>
# Installieren:
sudo apt install lsb-release       # Debian/Ubuntu
sudo dnf install redhat-lsb-core   # Fedora/RHEL
sudo zypper install lsb-release    # openSUSE/SUSE
</code>

==== hostnamectl funktioniert nicht ====

System nutzt kein systemd - verwenden Sie andere Methoden:
<code bash>
cat /etc/os-release
lsb_release -a
</code>
