Task Command Remarks

Disable pausing

session.

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 relog in 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 27.
