sc stands for search class. This command can search all possible classes loaded by JVM and show their information. The supported options are: [d]\u3001[E]\u3001[f] and [x:].

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 its code source, class specification, its class loader and so on. If a class is loaded by more than one class loader, then the class details will be printed several times
`[E]`	turn on regex match, the default behavior is wildcards match
`[f]`	print the fields info of the current class, MUST be used with `-d` together
`[x:]`	specify the depth of recursive traverse the static fields, the default value is '0' - equivalent to use `toString` to output
`[c:]`	The hash code of the special class's classLoader
`[classLoaderClass:]`	The class name of the ClassLoader that executes the expression.
`[n:]`	Maximum number of matching classes with details (100 by default)
