[Please, don't top-post; see the list Guidelines] That's not really it. The builtins are built in either because they're part of the Shell programming language or because they affect the Shell's own environment, e.g. its current directory. If cd were a separate program it would execute as a process, change its *own* directory, then terminate, leaving the Shell exactly where it was. As to knowing that 'type' is a builtin, you could just ask it about itself: type type poc -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
