type name ...
The type(1) command reports on how each name would be interpreted if used as a command name. For example, a name can be reported as a shell built-in, a function, an alias, or a keyword; if name is a separate utility, type(1) displays the path name.
The type(1) utility exits with status 0 for success, and >0 if an error occurred.
This command is a shell built-in.
