Using the prepared command lines

This component also provides a way to use the process command with prepared using the double brackets notations:

use Symfony\Component\Process\Process;

$process = Process::fromShellCommandline('echo "$name"');

$process->run(null, array('name' => 'elsa'));

Which means that you can use placeholder in order to have a process that can be changed only with the values and without changing the php code. The component will not escape the characters, you are responsible of doing so.
