Functions

func IsEnabled

func IsEnabled(name string) (bool, error)

IsEnabled returns true if auto start enabled for given service

Example

serviceName := "crond"

enabled, err := IsEnabled(serviceName)

if err != nil {
	fmt.Printf("Error: %v\n", err)
}

if enabled {
	fmt.Printf("Service %s is enabled\n", serviceName)
} else {
	fmt.Printf("Service %s is not enabled\n", serviceName)
}

func IsPresent

func IsPresent(name string) bool

IsPresent returns true if service is present in any init system

Example

serviceName := "crond"

if IsPresent(serviceName) {
	fmt.Printf("Service %s is present\n", serviceName)
} else {
	fmt.Printf("Unknown service %s\n", serviceName)
}

func IsWorks

func IsWorks(name string) (bool, error)

IsWorks returns service state

Example

serviceName := "crond"

works, err := IsWorks(serviceName)

if err != nil {
	fmt.Printf("Error: %v\n", err)
}

if works {
	fmt.Printf("Service %s is working\n", serviceName)
} else {
	fmt.Printf("Service %s is stopped\n", serviceName)
}

func SysV

func SysV() bool

SysV returns true if SysV is used on system

Example

if SysV() {
	fmt.Println("SysV init system is used")
}

func Systemd

func Systemd() bool

Systemd returns true if Systemd is used on system

Example

if Systemd() {
	fmt.Println("Systemd init system is used")
}

func Upstart

func Upstart() bool

Upstart returns true if Upstart is used on system

Example

if Upstart() {
	fmt.Println("Upstart init system is used")
}
