Output levels
There are 3 built-in output level. Shell::QUIET, Shell::NORMAL, Shell::VERBOSE.
The verbose and quiet output levels, map to the verbose and quiet output switches
present in most shells. Using Shell::QUIET for a message means it will always display.
While using Shell::VERBOSE means it will only display when verbose output is toggled.
Parameters

- A string or an array of strings to output
- integer $newlines optional 1
- Number of newlines to append

Returns the number of bytes returned from writing to stdout.
runCommand() public ¶
runCommand( array $argv , boolean $autoMethod false )
Runs the Shell with the provided argv.
Delegates calls to Tasks and resolves methods inside the class. Commands are looked up with the following order:
- Method on the shell.
- Matching task name.
main()method.
If a shell implements a main() method, all missing method calls will be sent to
main() with the original method name in the argv.
For tasks to be invoked they must be exposed as subcommands. If you define any subcommands, you must define all the subcommands your shell needs, whether they be methods on this class or methods on tasks.
Parameters
- array $argv
- Array of arguments to run the shell with. This array should be missing the shell name.
- boolean $autoMethod optional false
Set to true to allow any public method to be called even if it was not defined as a subcommand. This is used by ShellDispatcher to make building simple shells easy.
Returns
