O Guia Definitivo do Yii 1.1

Yii represents each console task in terms of a command. A console command is written as
a class extending from CConsoleCommand.
When we use the yiic webapp tool to create an initial skeleton Yii application, we may find
two files under the protected directory:
• yiic: this is an executable script used on Linux/Unix;
• yiic.bat: this is an executable batch file used on Windows.
In a console window, we can enter the following commands:
cd protected
yiic help
This will display a list of available console commands. By default, the available commands
include those provided by Yii framework (called system commands) and those developed
by users for individual applications (called user commands).
To see how to use a command, we can execute
yiic help
And to execute a command, we can use the following command format:
yiic [parameters...]
Creating Commands
Console commands are stored as class files under the directory specified by
CConsoleApplication::commandPath. By default, this refers to the directory protected/
commands.
A console command class must extend from CConsoleCommand. The class name must
be of format XyzCommand, where Xyz refers to the command name with the first letter in
upper case. For example, a sitemap command must use the class name
SitemapCommand. Console command names are case-sensitive.
Tip: By configuring CConsoleApplication::commandMap, one can also have command
classes in different naming conventions and located in different directories.
To create a new command, one often needs to override CConsoleCommand::run() or
develop one or several command actions (to be explained in the next section).
When executing a console command, the CConsoleCommand::run() method will be
invoked by the console application. Any console command parameters will be passed to
the method as well, according to the following signature of the method:
