en:Simple CLI (3.5.1)

From WekaDoc

The Simple CLI provides full access to all Weka classes, i.e., classifiers, filters, clusterers, etc., but without the hassle of the CLASSPATH (it facilitates the one, with which Weka was started).

It offers a simple Weka shell with separated commandline and output.

Commands

The following commands are available in the Simple CLI:

• java <classname> [<args>]
  invokes a java class with the given arguments (if any)
• break
  stops the current thread, e.g., a running classifier, in a friendly manner
• kill
  stops the current thread in an unfriendly fashion
• cls
  clears the output area
• exit
  exits the Simple CLI
• help [<command>]
  provides an overview of the available commands if without a command name as argument, otherwise more help on the specified command

Invocation

In order to invoke a Weka class, one has only to prefix the class with "java". This command tells the Simple CLI to load a class and execute it with any given parameters. E.g., the J48 classifier can be invoked on the iris dataset with the following command:

java weka.classifiers.trees.J48 -t c:/temp/iris.arff

This results in the following output:
