Command Type

Usage Guidelines

If value contains white space or other special (shell) characters, you must use quotation marks. If value has a space as its last character, the next command line word is checked for an alias (normally, only the first word on a command line is checked).

An equal sign (=) is required between the name and value of the alias.

Example

This example shows how to display a list of available alias commands and how to create an alias for the set command:

rommon 1 > alias
r=repeat
h=history
?=help
b=boot
ls=dir
i=reset
k=stack
rommon 2 > alias s=set
rommon 3 > alias
r=repeat

ls=dir
i=reset
k=stack
s=set
rommon 4 > s
