Description copied from interface: Command

Executes this command and returns a LineProcessor object. Calling this method initiates the command execution, but the real processing of the command takes place when lines are passed to the returned LineProcessor object. The command execution is terminated by calling LineProcessor.finish().

The command writes its output to the specified output object. Depending on the command implementation, the output is written when lines are passed to the LineProcessor returned by this method, or when the execution terminates with the finish() call.

Parameters:

context - context object providing access to the current directory, environment variables and other information useful for the command during its execution

output - the output to write to

Returns:

true if another invocation with more input is expected, and false if this command has completed and no other invocation is required.
