Run Linux command from Symfony command


How can I run a simple Linux command in a Symfony command?

E.g. I want to run ssh [email protected] -p port at the end of the command…

I’ve tried:

$input = new StringInput('ssh [email protected] -p port');
$this->getApplication()->run($input, $output);

But that throws the following exception: `The “-p” option does not exist.“

It seems to be executed in the same “context” of my Symfony command.

First of all, try to execute a simple/plain command (ls) to see what happens, then move on to your special command.


use Symfony\Component\Process\Process;
use Symfony\Component\Process\Exception\ProcessFailedException;

$process = new Process('ls -lsa');

// executes after the command finishes
if (!$process->isSuccessful()) {
    throw new ProcessFailedException($process);

echo $process->getOutput();

As you can see above, if you put the piece of code in one of your controllers for testing purposes, ls -lsa lists files/folders stored under web folder!!!

You can just do shell_exec('ls -lsa'); as well which is what I sometimes do. e.g. shell_exec('git ls-remote url-to-my-git-project-repo master');
