Command Line Features

Following are some of the command line features supported by the CLI Agent in String Mode and also in Multi-Protocol CLI Agent.  

• Command History

• Command Line Editing

• Command Completion

• Command Usage

• Escape Key

Command History

• History option enables CLI Agent to record all the commands which are executed till now.

• You can use UP-Arrow or DOWN-Arrow keys to traverse the history list.

• While traversing the history list, you can execute the same command or you can modify the required command and execute it

Command Line Editing

• If you typed a command wrongly, then you can use the LEFT arrow key and RIGHT arrow key to traverse through that command and change the parameter values or the command name as required.

• DEL key can be used to delete a character available in the current cursor position.

• BACKSPACE key can be used to delete a character available in the previous position to the current cursor position.  

Command Completion

• To know the list of commands available / registered in the CLI Agent, press TAB key from the CLI prompt

• To know the list of commands starting with the specific character, type that character and on pressing the TAB key, the CLI Agent lists the available CLI command starting with that character and will wait for the further input

• Command completion is available for Commands and also for Sub-commands

• Question mark ( ? ) key can be used to know the list of commands registered with the CLI Agent

• When Question mark ( ? ) key is used after typing a character, then the agent will list the available CLI commands starting with that character and will return to the CLI prompt and not as like TAB key functionality

Command Syntax / Usage

• To know the syntax or usage of a command registered in the CLI Agent, type the couple of characters of that command and press TAB key from the CLI prompt.

• Alternatively, you can also type the entire command name and press the ENTER key.

• If there are sub commands / objects in the commands that you have executed, the usage will be shown based on the level from where the return key is pressed.

• For example, suppose you have a command in the following format
  
   

show ip tcp header_compresssion route summary supernets_only interface brief switches [--userinfo] [ipaddress param<STR>] protocols

 
And the usage for this command will be shown based on the location where you press the enter key
