3: Command Line Interface Using Keyboard Shortcuts and CLI One useful shortcut built into Evolution OS™ 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. Typing the first few characters of a command, then hitting the key displays the first command that begins with those characters. Hitting the key again displays the next command that begins with the original characters typed. You can press to execute the command or you can backspace to edit any parameters. The following key combinations are allowed when configuring the device server using the CLI: Ctrl + a: place cursor at the beginning of a line Ctrl + b: backspace one character Ctrl + d: delete one character Ctrl + e: place cursor at the end of the line Ctrl + f: move cursor forward one character Ctrl + k: delete from the current position to the end of the line Ctrl + l: redraw the command line Ctrl + n: display the next line in the history Ctrl + p: display the previous line in the history Ctrl + u: delete entire line and place cursor at start of prompt Ctrl + w: delete one word back Ctrl + z: a shortcut for the exit command Esc + b: move cursor back one word Esc + f: move cursor forward one word Understanding the CLI Level Hierarchy The CLI hierarchy is a series of levels. Arranging commands in a hierarchy of levels provides a way to organize and group similar commands, provide different levels of security, and reduce the complexity and number commands and options presented to a user at one time. When you start a command line session, you begin at the login level. This level can be password protected and provides access to high level status, a few diagnostic commands, and the enable level. Further device information and configuration are accessed via the enable level. The enable level can also be password protected and is the gateway to full configuration and management of the device server. There are commands for gathering and effecting all elements of device status and configuration, as well as commands that take you to additional levels. For instance, tunnel specific status and configuration is found under the "tunnel" level, and network specific status and configuration commands are found under the "configuration" level. An overview of the levels in the XPort Pro is presented in Figure 3-1. XPort Pro Command Reference 11
