In the previous example we looked at spawning external processes. We do the when we need a external process accessible to running Go process. Sometimes we just want to completely replace the current Go process with another one. To does this we'll use Go ' s implementation of the classic EXEC function

Package Mainimport ("OS"    "os/exec"    "Syscall"Func Main () {binary, Lookerr:= Exec. Lookpath ("ls")    ifLookerr! =Nil {panic (Lookerr)} args:= []string{"ls"," -A","- L","- H"} env:=OS. Environ () Execerr:=Syscall. Exec (binary, args, env)ifExecerr! =Nil {panic (execerr)}}
