single

single provides a mechanism to ensure, that only one instance of a program is running.

package main

import (
    "log"
    "time"

    "github.com/marcsauter/single"
)

func main() {
    s := single.New("name")
    s.Lock()
    defer s.Unlock()
    log.Println("working")
    time.Sleep(60 * time.Second)
    log.Println("finished")
}

The package currently supports linux, solaris and windows.
