Unix commands

Moler ships with more than 100 ready-made Unix command parsers. Every command class accepts a connection object, sends the underlying shell command, and returns a structured result dictionary when parsing is complete.

All Unix command classes inherit from GenericUnixCommand (module moler.cmd.unix.genericunix). The base class handles prompt detection and newline splitting; concrete classes implement build_command_string() and on_new_line() parsing.
