Parameter	Type	Description

Example

package main

import (
	"fmt"
	"log"

	"github.com/scagogogo/composer-skills/pkg/installer"
)

func main() {
	distro, err := installer.DetectLinuxDistro()

Advanced

• Detection order: /etc/os-release → lsb_release command → distro-specific files (/etc/redhat-release, etc.) → fallback to available package managers. 🛠️
• Supports major distributions such as Ubuntu/Debian, Fedora/CentOS/RHEL, Arch, Alpine, openSUSE, and Gentoo. 📦
• The result is used by InstallComposerViaPackageManager and InstallPHP. 🔗
