xPico® Wi-Fi® Embedded Device Server User Guide 72
Navigating the CLI Hierarchy
The CLI is organized into a hierarchy of levels. Each level has a group of commands for a specific
purpose. For example, to view diagnostic or device status, one would navigate to the status level
where they could then navigate to diagnostics or device.
To move to a different level—Enter the name of the level from within its parent level. For
example, to enter the file system level, type file system at the enable prompt.
To exit and return to one level higher—Type exit and press the Enter key.
To view the current configuration, enter the config level by typing config.
To view the list of commands available at the current level—Type the question mark ?. Items
within < > (e.g. <string>) are required parameters.
To view the available commands and explanations—Type the asterisk (*).
To view the list of commands available for a partial command—Type the partial command
followed by the question mark "?". For example: config>? displays a list of all config
commands at the config level.
To view available commands and their explanations for a partial command—Type an asterisk
(*). For example: config Access Point>* displays a list of all accesss point commands
and descriptions at the config > access point level.
To view SPI configurations, enter the config level by typing config at the root level, and then
the SPI level by typing SPI.
To view the tlog, type tlog or t at the root level.
Using Keyboard Shortcuts and CLI
One useful shortcut built into xPico Wi-Fi embedded device server is that the complete text of a
command does not have to be entered to issue a command. Typing just enough characters to
uniquely identify a command, then hitting enter, can be used as a short cut for a command. For
example, at the enable level, "sh" can be used for the "show" command.
Tab Completion is also available using the Tab and Enter keys on the keyboard. Typing the first
few characters of a command, then hitting the Tab key displays the first command that begins with
those characters. Hitting the Tab key again displays the next command that begins with the
original characters typed. You can press Enter to execute the command or you can backspace to
edit any parameters.
The following key combinations are allowed when configuring the Pico Wi-Fi embedded device
server using the CLI:
