I did this recently… let me find the code…

```julia
"Run a Cmd object, returning the stdout & stderr contents plus the exit code"
function execute(cmd::Cmd)
  out = Pipe()
  err = Pipe()

  process = run(pipeline(ignorestatus(cmd), stdout=out, stderr=err))
  close(out.in)
  close(err.in)

  (
    stdout = String(read(out)), 
    stderr = String(read(err)),  
    code = process.exitcode
  )
end

execute(`ls`)
execute(`ls --invalid-option`)

```
