show Commands

You have access to a variety of show commands that display router and protocol information. You can filter the output of a show command by specifying | (the UNIX pipe symbol), one of the following keywords, and either a case-sensitive text string or a regular expression.

begin—Displays output beginning with the first line that contains the text string or regular expression
include—Displays output lines that contain the text string or regular expression and excludes lines that do not contain the text string or regular expression
exclude—Displays output lines that do not contain the text string or regular expression and excludes lines that do contain the text string or regular expression

For a list of regular expressions, see Regular Expressions. You can press Ctrl+c to interrupt the show command output.

Note: The system does not recognize beginning spaces of the text string. For example, if you enter include IP as the text string on which to filter, the system ignores the space and displays lines that include words such as RIP.

Example 1

In the following example, the output display starts with the first line that contains the string inter. The system omits all the preceding lines of the output from the display because none of them contains the string inter.

Example 2

In the following example, the output display consists only of lines that contain the string ip. The system omits all other lines of the output from the display because none of them contains the string ip.
