# run method

Future<ProcessResult> run (String executable, List<String> arguments, { String workingDirectory, Map<String, String> environment, bool includeParentEnvironment: true, bool runInShell: false, Encoding stdoutEncoding: systemEncoding, Encoding stderrEncoding: systemEncoding })

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

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.

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.

    Process.run('grep', ['-i', 'main', 'test.dart']).then((result) {
      stdout.write(result.stdout);
      stderr.write(result.stderr);
    });

## Implementation

    external static Future<ProcessResult> run(
        String executable, List<String> arguments,
        {String workingDirectory,
        Map<String, String> environment,
        bool includeParentEnvironment: true,
        bool runInShell: false,
        Encoding stdoutEncoding: systemEncoding,
        Encoding stderrEncoding: systemEncoding});
