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 ***must*** be used 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 `sub-class`, you can just turn it off with [options](options.md) as `options disable-sub-class true`.

### Usage

Check the static fields of a class using `sc -df class-name`

```shell
$ sc -df org.apache.commons.lang.StringUtils
