Filtering the output from a display command
You can use one of the following methods to filter the output from a display command:
•
Specify the | { begin | exclude | include } regular-expression option at the end of the command.
•
When the system pauses after displaying a screen of output, enter a forward slash (/), minus
sign (-), or plus sign (+) plus a regular expression to filter subsequent output. The forward slash
equals the keyword begin, the minus sign equals the keyword exclude, and the plus sign
equals the keyword include.
The following definitions apply to the begin, exclude, and include keywords:
•
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 that supports the special
characters in

Meaning
Starting sign. Matches a line that
starts with string.
Ending sign. Matches a line that
ends with string.
Remarks
The default for a session depends on the
setting of the screen-length command in user
interface view. The default of the
screen-length command is pausing between
screens of output and displaying up to 24 lines
on a screen.
This command is executed in user view, and
takes effect only for the current session. When
you relog in to the device, the default is
restored.
Remarks
For example, regular expression "^user" matches
a line beginning with "user", not "Auser".
For example, regular expression "user$" only
matches a line ending with "user", not "userA".
