Examples of org.jnode.shell.CommandLine

org.jnode.shell.CommandLine
This class represents the command line as command name and a sequence of argument strings. It also can carry the i/o stream environment for launching the command.
TODO This class needs to be fully "shell and command syntax agnostic". TODO Get rid of API methods using a String argument representation. @author crawley@jnode.org
