run static method

Starts a process and runs it non-interactively to completion. The process run is executable with the specified arguments.

Using an absolute path for executable is recommended since resolving the executable path is platform-specific. On Windows, both any PATH set in the environment map parameter and the path set in workingDirectory parameter are ignored for the purposes of resolving the executable path.

Use workingDirectory to set the working directory for the process. Note that the change of directory occurs before executing the process on some platforms, which may have impact when using relative paths for the executable and the arguments.

Use environment to set the environment variables for the process. If not set the environment of the parent process is inherited. Currently, only US-ASCII environment variables are supported and errors are likely to occur if an environment variable with code-points outside the US-ASCII range is passed in.

If includeParentEnvironment is true, the process's environment will include the parent process's environment, with environment taking precedence. Default is true.

If runInShell is true, the process will be spawned through a system shell. On Linux and OS X, /bin/sh is used, while %WINDIR%\system32\cmd.exe is used on Windows.

NOTE: On Windows, if executable is a batch file ('.bat' or '.cmd'), it may be launched by the operating system in a system shell regardless of the value of runInShell. This could result in arguments being parsed according to shell rules. For example:

void main() async {
  // Will launch notepad.
  await Process.run('test.bat', ['test&notepad.exe']);
}

The encoding used for decoding stdout and stderr into text is controlled through stdoutEncoding and stderrEncoding. The default encoding is systemEncoding. If null is used no decoding will happen and the ProcessResult will hold binary data.

Returns a Future<ProcessResult> that completes with the result of running the process, i.e., exit code, standard out and standard in.

The following code uses Process.run to grep for main in the file test.dart on Linux.

var result = await Process.run('grep', ['-i', 'main', 'test.dart']);
stdout.write(result.stdout);
stderr.write(result.stderr);
