+### 55. 使用CLI
+
+一旦安装好CLI，你可以输入`spring`来运行它。如果你不使用任何参数运行`spring`，将会展现一个简单的帮助界面：
+```shell
+$ spring
+usage: spring [--help] [--version]
+       <command> [<args>]
+
+Available commands are:
+
+  run [options] <files> [--] [args]
+    Run a spring groovy script
+
+  ... more command help is shown here
+```
+你可以使用`help`获取任何支持命令的详细信息。例如：
+```shell
+$ spring help run
+spring run - Run a spring groovy script
+
+usage: spring run [options] <files> [--] [args]
+
+Option                     Description
+------                     -----------
+--autoconfigure [Boolean]  Add autoconfigure compiler
+                             transformations (default: true)
+--classpath, -cp           Additional classpath entries
+-e, --edit                 Open the file with the default system
+                             editor
+--no-guess-dependencies    Do not attempt to guess dependencies
+--no-guess-imports         Do not attempt to guess imports
+-q, --quiet                Quiet logging
+-v, --verbose              Verbose logging of dependency

+--watch                    Watch the specified file for changes
+```
+`version`命令提供一个检查你正在使用的Spring Boot版本的快速方式：
+```shell
+$ spring version
+Spring CLI v1.3.0.BUILD-SNAPSHOT
+```
