+sc
+==
+
+Check the profiles of the loaded classes.
+
+Abbreviated from “Search-Class”; with the help of this command, you can search out all the loaded classes in JVM. Supported options are: `[d]`、`[E]`、`[f]` and `[x:]`.
+
+Options
+-------
+
+### Specification
+
+|Name|Specification|
+|---:|:---|
+|*class-pattern*|pattern for the class name|
+|*method-pattern*|pattern for the method name|
+|[d]|print the details of the current class including the source file, class declaration, the class loaders and the like.<br/>F.Y.I if a class is loaded by several class loaders, then the class will be printed several times|
+|[E]|turn on regx matching while the default is wildcards matching|
+|[f]|print the fields info of the current class, which should be used along with `-d`|
+|[x:]|the depth to print the static fields, whose default is `0` - directly invoke the `toString()`|
+
+Tip: 
+1. *class-patten* supports full qualified class name (e.g. com.taobao.test.AAA and com/taobao/test/AAA) 
+2. `sc` turned on the `sub-class` matching in default mode, if you do want to hide the `sub-class` please just turn it off via `options disable-sub-class true`.
+
+### Usage
+
+Check the static fields of a class using `sc -df class-name`
+
+```shell
