mixed —mustRun()
Runs the process.
public
mustRun(OutputInterface $output, string|Process $cmd[, string|null $error = null ][, callable|null $callback = null ]) : Process
This is identical to run() except that an exception is thrown if the process exits with a non-zero exit code.
Parameters

- $cmd : string|Process
-
An instance of Process or a command to run
- $error : string|null = null
-
An error message that must be displayed if something went wrong
- $callback : callable|null = null
-
A PHP callback to run whenever there is some output available on STDOUT or STDERR
