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 following keywords:

Keyword
Usage

append

Append redirected output to URL (URLs supporting append operation only)

begin

Begin with the line that matches

count

Count number of lines which match regexp

exclude

format

include

redirect

tee

Output redirection keywords:

These extenstions can also be added to more commands.
