namespace origin command
Returns the fully-qualified name of the original command to which the imported command command refers. When a command is imported into a namespace, a new command is created in that namespace that points to the actual command in the exporting namespace. If a command is imported into a sequence of namespaces a, b,...,n where each successive namespace just imports the command from the previous namespace, this command returns the fully-qualified name of the original command in the first namespace, a. If command does not refer to an imported command, the command's own fully-qualified name is returned.
