Functions

func DNSlookup added in v0.2.6 

func DNSlookup(host string, server string, qtype string, timeout int) ([]string, error)

func DetectDistro added in v0.1.4 

func DetectDistro() string

DetectDistro attempts to detect which Linux distribution this computer is using. One of "ubuntu", "redhat" (including Centos), "alpine", "arch", or "debian". If it can't decide, it returns an empty string.

func DetectPackageManager added in v0.1.4 

func DetectPackageManager() string

DetectPackageManager attempts to detect whether or not the system is using "dpkg", "rpm", "apk", or "pacman" package managers. It first attempts to detect the distro. If that fails, it falls back to finding package manager executables. If that fails, it returns the empty string.

func DetectService added in v0.1.4 

func DetectService() string

DetectService attempts to detect what kind of service management the system is using, "systemd", "upstart", "alpineinit", or "init". It looks for systemctl command to detect systemd, and falls back on DetectDistro otherwise. If it can't decide, it returns "init".
