## 创建自定义命令行 第一步，配置command.php文件，目录在application/command.php ~~~ <?php return [     'app\home\command\Test', ]; ~~~ 第二步，建立命令类文件，新建application/home/command/Test.php ~~~ <?php namespace app\home\command; use think\console\Command; use think\console\Input; use think\console\Output; class Test extends Command {     protected function configure()     {         $this->setName('test')->setDescription('Here is the remark ');     }     protected function execute(Input $input, Output $output)     {         $output->writeln("TestCommand:");     } } ~~~ 这个文件定义了一个叫test的命令，备注为Here is the remark， 执行命令会输出TestCommand。 第三步，测试-命令帮助-命令行下运行 ~~~ php think ~~~ 输出 ~~~ Think Console version 0.1 Usage:   command [options] [arguments] Options:   -h, --help            Display this help message   -V, --version         Display this console version   -q, --quiet           Do not output any message       --ansi            Force ANSI output       --no-ansi         Disable ANSI output   -n, --no-interaction  Do not ask any interactive question   -v|vv|vvv, --verbose  Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug Available commands:   build              Build Application Dirs   clear              Clear runtime file   help               Displays help for a command   list               Lists commands   test               Here is the remark  make   make:controller    Create a new resource controller class   make:model         Create a new model class  optimize   optimize:autoload  Optimizes PSR0 and PSR4 packages to be loaded with classmaps too, good for production.   optimize:config    Build config and common file cache.   optimize:route     Build route cache.   optimize:schema    Build database schema cache. ~~~ 第四步，运行test命令 ~~~ php think test ~~~ 输出 ~~~ TestCommand: ~~~
