EFI Shell commands -- ALIAS(在一個EFI Shell環境中，顯示、建立、或刪除別名)

Displays, creates, or deletes aliases in the EFI Shell environment.

ALIAS [-d|-v] [sname] [value]


    -d       - Deletes an alias
    -v       - Volatile variable
    sname    - Alias name
    value    - Original name

Note:
    1. 'sname' should not be an internal EFI Shell command.
    2. 'value' can be an internal EFI Shell command, a script, or an EFI
       application. However, any other values are also acceptable.
    3. ALIAS values are stored in EFI NVRAM and will be retained between boots
       unless the '-v' option is specified.
    4. ALIAS will not add a nonvolatile alias when a volatile alias of the same
       name already exists, or vice versa.

Examples:
  * To display all aliases in the EFI Shell environment:
    Shell> alias
        md   : mkdir
        rd   : rm

  * To create an alias in the EFI Shell environment:
    Shell> alias myguid guid
    Shell> alias
        md     : mkdir
        rd     : rm
        myguid : guid

  * To delete an alias in the EFI Shell environment:
    Shell> alias -d myguid
    Shell> alias
        md   : mkdir
        rd   : rm

  * To add a volatile alias in the current EFI environment, which has a star *
    at the line head. This volatile alias will disappear at next boot.
    Shell> alias -v fs0 floppy
    Shell> alias
