Command show will print list of directories or modules in current depth.

You can press tab to autocomplete your command or tab tab to show available options. E.g. command load tab-tab will print all available modules disregarding your current path.

You can use load command to start a specific module of REXT. When loading module not just changing directory new sub-console is actually created. You can see that by typing help command. The list of available commands changed. REXT modules always follow the same convention for paths type/vendor/module.

Description: Generates WPS pin for Arris DG860A router based on mac
Based on: Work of Justin Oberdorf

Options:
Name Description
mac MAC address used as input for WPS pin generation
misc/arris/dg860a_mac2wps>
Here you can use command mac to print current MAC address or use the command set to set new MAC address. After you are done with the configuration of module properties you can execute it with run command (this applies for all modules disregarding of their type). Some basic validations are in place that will prevent you in setting incorrect values.
misc/arris/dg860a_mac2wps>mac 00:00:00:00:00 misc/arris/dg860a_mac2wps>set mac 11:22:33:44:55 Error: please provide valid MAC address misc/arris/dg860a_mac2wps>set mac 00:50:56:C0:00:08 MAC set to: 00:50:56:C0:00:08 (VMware, Inc.) misc/arris/dg860a_mac2wps>run Success: WPS PIN: 62175401
Now that the module was executed you may wish to load different module. You can do this by typing back command. This command will exit only the current module and return you to the main REXT console. If you type exit it will exit REXT.
You can use unload command to get to REXT root directory. But this is not necessary since load command works with absolute paths you can use.
