CConsoleApplication represents a console application.

CConsoleApplication extends CApplication by providing functionalities specific to console requests. In particular, it deals with console requests through a command-based approach:

A console application consists of one or several possible user commands;
Each user command is implemented as a class extending CConsoleCommand;
User specifies which command to run on the command line;
The command processes the user request with the specified parameters.

The command classes reside in the directory commandPath. The name of the class follows the pattern: <command-name>Command, and its file name is the same as the class name. For example, the 'ShellCommand' class defines a 'shell' command and the class file name is 'ShellCommand.php'.

To run the console application, enter the following on the command line:

php path/to/entry_script.php <command name> [param 1] [param 2] ...

You may use the following to see help instructions about a command:

php path/to/entry_script.php help <command name>

commandPath Example

If you need to modify the commandPath, put something like the following into protected/config/main.php or console.php:

    'commandPath' => dirname(__FILE__).DIRECTORY_SEPARATOR.'..'.DIRECTORY_SEPARATOR.'commands'.DIRECTORY_SEPARATOR.'shell',

This would add all commands from the protected/commands/shell directory. The value needs to be something that the PHP realpath() function will accept and must be a directory that exists.
