Feature Specifications for the Show Command Output Redirection Feature

Feature History
Release	Modification
12.0(21)S	This feature was introduced.
12.2(13)T	This feature was integrated into Cisco IOS Release 12.2 T.

Determining Platform Support Through Cisco Feature Navigator

Cisco IOS software is packaged in feature sets that are supported on specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.

Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.

To access Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions found at this URL:

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

Availability of Cisco IOS Software Images

Platform support for particular Cisco IOS software releases is dependent on the availability of the software images for those platforms. Software images for some platforms may be deferred, delayed, or changed without prior notice. For updated information about platform support and availability of software images for each Cisco IOS software release, refer to the online release notes or, if supported, Cisco Feature Navigator.

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 redirect, append, or tee keywords.

These extenstions can also be added to more commands.

How to Use the Show Command Enhancement

No configuration tasks are associated with this enhancement. For usage guidelines, see the command pages in the "Command Reference" section.

Additional References

For information about specific show and more commands, see the Cisco IOS Documentation Set for Release 12.2 T, available on Cisco.com.

No standards, MIBs, or RFCs are applicable to this feature.
