Alias command

From NetworkCommands

A command available on most Cisco paltforms; used to create, modify or delete command aliases. A command alias is a user-assigned alternative command name that is entered at the CLI instead of the normal command. The user-assigned name would normally be shorter than the original command.

Command aliases accept any variables and keywords that the full command normally would.

Built-In Aliases

The following aliases are 'built-in' (but won't show up in configuration files or the output from a show run);

 Alias:                Executes Command:
 h                     help
 lo                    logout
 p                     ping
 r                     resume
 s                     show
 u                     undebug
 un                    undebug
 w                     where

Usage Examples

A number of examples are provided below. The logic behind the abbreviations used is as follows:

• Whole words are abbreviated to a single letter, i.e. show = s
• Acronyms are not abbreviated, i.e. ip remains as ip EXCEPT acronyms that can be considered whole words in themselves, such as NAT or PAT, so nat = n, pat = p
• Compound phrases are abbreviated using each component word, i.e. access-list = al

Usage Notes

Note that aliases on CSS platforms are stored on the local disk (usually a PCMCIA device) and cannot be accessed if the disk has been removed or has failed.
