Description
This command displays, creates, or deletes aliases in the UEFI Shell environment. An
alias provides a new name for an existing UEFI Shell command or UEFI application.
Once the alias is created, it can be used to run the command or launch the UEFI
application.
There are some aliases that are predefined in the UEFI Shell environment. These
aliases provide the MS-DOS and UNIX equivalent names for the file manipulation
commands. See Built-In Aliases (section 3.6.4) for more details.
Al
iases will be retained even after exiting the shell unless the –v option is specified. If
-v is specified then the alias will not be valid after leaving the shell.
