Pausing between screens of output

If the output being displayed is more than will fit on one screen, the system automatically pauses after

displaying a screen. By default, up to 24 lines can be displayed on a screen. To change the screen length,

use the screen-length screen-length command. For more information about this command, see

Fundamentals Command Reference. To control output, use keys in Table 5.

screen-length disable

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 log in again to the device, the default is

restored.

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 (+), and 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 Table 6.
