Information About show Command Output Redirection

This feature enhances the show commands in the Cisco IOS CLI to allow large amounts of data output to be written directly to a file for later reference. This file can be saved on local or remote storage devices such as Flash, a SAN Disk, or an external memory device.

For each show command issued, a new file can be created, or the output can be appended to an existing file. Command output can optionally be displayed on-screen while being redirected to a file by using the tee keyword. Redirection is available using a pipe (|) character after any show command, combined with the followingkeywords:

Output redirection keywords:

Usage

append

begin

count

exclude

redirect
