output.
Adding a Filter at the --More-- Prompt
You can specify a filter at the --More-- prompt of a show command output by entering a forward slash
(/) followed by a regular expression. The filter remains active until the command output finishes or is
interrupted (using Ctrl-Z or Ctrl-C). The following rules apply to this technique:
• If a filter is specified at the original command or previous --More-- prompt, a second filter cannot
be applied.
• The use of the begin keyword does not constitute a filter.
• The minus sign (–) preceding a regular expression displays output lines that do not contain the
regular expression.
• The plus sign (+) preceding a regular expression displays output lines that contain the regular
expression.
In the following example, the user adds a filter at the
--More-- prompt to show only the lines in the
remaining output that contain the regular expression “ip”.

end
Tip On most systems, Ctrl-Z can be entered at any time to interrupt the output and return to EXEC mode.

Patterns.”
