docstring: Creates a Process instance as a command-line to be run in a shell wrapper.
  
  Command-lines are parsed by the shell of your OS (/bin/sh on Unix-like, cmd.exe on Windows.)
  This allows using e.g. pipes or conditional execution. In this mode, signals are sent to the
  shell wrapper and not to your commands.
  
  In order to inject dynamic values into command-lines, we strongly recommend using placeholders.
  This will save escaping values, which is not portable nor secure anyway:
  
  $process = Process::fromShellCommandline('my_command "$MY_VAR"');
  $process->run(null, ['MY_VAR' => $theValue]);
  
  @param string         $command The command line to pass to the shell of the OS
  @param string|null    $cwd     The working directory or null to use the working dir of the current PHP process
  @param array|null     $env     The environment variables or null to use the same environment as the current PHP process
  @param mixed|null     $input   The input as stream resource, scalar or \Traversable, or null for no input
  @param int|float|null $timeout The timeout in seconds or null to disable
  
  @throws RuntimeException When proc_open is not installed
