Arguments

Description

The alias command is used to maintain simple command line aliases. These aliases are shorthand for longer expressions. When the pattern %{name} appears in a command line, including in a script, the corresponding value will be substituted. Aliases may be nested.

If no value is provided, then the current value of the alias is displayed.

If the system supports non-volatile configuration data via the fconfig command (see Section 225.5, “Persistent State Flash-based Configuration and Control ”), then the value will be saved and used when the system is reset.

Examples

Set an alias.

RedBoot> alias joe "This is Joe"
Update RedBoot non-volatile configuration - continue (y/n)? n

Display an alias.

RedBoot> alias joe
'joe' = 'This is Joe'

Use an alias. Note: the "=" command simply echoes the command to to console.

RedBoot> = %{joe}
This is Joe

Aliases can be nested.

RedBoot> alias frank "Who are you? %{joe}"
Update RedBoot non-volatile configuration - continue (y/n)? n
RedBoot> = %{frank}
Who are you? This is Joe

Notice how the value of %{frank} changes when %{joe} is changed since the value of %{joe} is not evaluated until %{frank} is evaluated.

RedBoot> alias joe "This is now Josephine"
Update RedBoot non-volatile configuration - continue (y/n)? n
RedBoot> = %{frank}
Who are you? This is now Josephine
