Current Process

import "os"
import "os/user"

os.Executable()
os.Getpid()
os.Getppid()
os.Getuid()
os.Getgid()

os.Exit(1)              // exit process with exitcode '1'

// environment
envvars := os.Environ() // ["FOO=bar", "BAR=baz", ...]
pwd, err := os.Getwd()  // get current pwd/cwd
user.Current()          // 'will'

Manage Processes

import "syscall"
import "os"
import "os/signal"

proc := os.Process.FindProcess(1234)  // find process with pid
proc.Kill()                           // kill process (-9/SIGKILL)
proc.Signal(os.Iterrupt)              // send SIGINT to process (looks like you can use any syscall.SIG*)
proc.Wait()                           // wait for process to end

syscall.Kill(1234, syscall.SIGINT)    // send SIGINT to pid 1234
