Command CLI Features and Navigation Options

[ LiB ]

Like most of Cisco IOS CLIs, the IDS 4.0 contains several common keyboard and editing features that are useful for navigating and entering commands. Table 7.1 displays a list of the common CLI keyboard commands that you should know.

Table 7.1. CLI Keyboard Operations

Option	Function
?	The ? lists all the commands at the current location or the next parameters required for a command.
Command abbreviations	The CLI supports abbreviating commands, so you don't need to remember the entire words. For example, you can abbreviate the command configure by using just three letters , con .
Tab key	Pressing the Tab key lets the system complete the word if you type only a portion of it. For example, if you type con and then press the Tab key, it completes the abbreviation to the word configure . However, remember that you don't have to use the Tab key to complete abbreviated words; the system supports command abbreviations.
Previous command	The system keeps a history list of the commands you have already typed. This list allows you to recall these commands if needed again. By pressing the up arrow or Ctrl+P, you can scroll back through the command history until you find the same command you used before.
Next command	By pressing the down arrow or the Ctrl+N key, you can scroll forward through the command history.
[default]	Values inside brackets are default values. If you press Enter, the systems uses the value in brackets unless you manually enter a different value.
Exit	Exit the current configuration mode and return to global configuration mode.
End	Exit the current configuration mode and return to exec mode.
show settings	This command is not always offered at every level of the IDS CLI. But when available, it offers detailed information about the settings at the current level when applicable .
