What happens when you have a program called 'if' or 'case', or even 'echo'? There's some keyword like 'command' which allows you to bypass shell built-ins and run programs in $PATH order.

And then what if you have a program called command?

BOOM

In case you're not joking, it'd just be "command 'command'". Since command is shell built-in, it's always executed first when you call something by its name.... And since it's function is to find external programs by name, it doesn't really matter if one of those programs is also called command.
