Yes, it is a keyword, a keyword parameter that tells CLI command what to do
(yes, a keyword that may be taken verbatim or translated into an internal
command parameter(s), a keyword that represents an action).
But, it is not a command, or parameter of type command.

Well, a second nature ... But, it is an honor :-)

To drive the point:
let's assume that it is a valid syntax to pass a parameter like this:
"ls -al"
or much better, command="<command>", like this:
command="ls -al"
then it would be clear that a command (parameter) is passed to CLI command.
This kind of command parameter passing fulfilles the definition of a command
as referenced.

If you are familiar with C function system(), you will have easier time to
understand:
http://www.cplusplus.com/reference/clibrary/cstdlib/system/
The prototype is:
int system ( const char * command );
The command "ls -al" (yes, it is a command as referenced) is a parameter to
system() function:
system("ls -al");
It just says, execute that command "ls -al" in the existing execution
environment.

The reason I go so by the book about it is that "words have meaning" and
definitions :-)
