The unalias command removes a previously defined alias. You can delete all aliases using the -all option. Aliases defined in the tvdinit.tvdfile are also deleted.
Examples
unalias step2
Removes the step2 alias; step2 is undefined and can no longer be used. If step2 was included as part of the definition of another command, that command no longer works correctly. However, the CLI only displays an error message when you try to execute the alias that contains this removed alias.
