go-pid-file

Tiny tool to create and read pid files

Before start something:

pf := pid.NewFile("path/to/file")

if err := pf.Create(); err := nil {
    log.Fatal("process already running")
}
defer pf.Remove()

// start something useful

Before stop something:

pf := pid.NewFile("path/to/file")

process, err := pf.Process();
if err != nil {
    log.Fatal(err)
}
if process != nil {
    // stop process
}
