the following operations to proceed:

Filtering output information

Use regular expressions in display commands to filter output information.
The following methods are available for filtering output information:
Enter the begin, exclude, or include keyword plus a regular expression in the display command to
•
filter the output information.
When the system displays the output information in multiple screens, use /, - or + plus a regular
•
expression to filter subsequent output information. The / character equals the keyword begin, -
equals the keyword exclude, and + equals the keyword include.
The following definitions apply:
begin—Displays the first line that matches the specified regular expression and all lines that follow.
•
exclude— Displays all lines that do not match the specified regular expression.
•
include—Displays all lines that match the specified regular expression.
•
A regular expression is a case-sensitive string of 1 to 256 characters. It supports the following special
characters:
