The following commands will report the TCP/IP configuration on Unix, MacOS X, Windows, and Cisco operating systems. By "Unix" I mean anything vaguely Unix-like — Solaris, Linux, BSD, Tru64, AIX, IRIX, HP-UX, etc., plus MacOS X.
Note that the Cisco IOS allows for command abbreviation. That is, instead of:
router> show interfaces
you could simply type:
router> sh in
However, I prefer to use the entire command, using the tab key for command completion. You type just sh and then press :
router> sh
and the system finishes the command itself:
router> show
At that point you could press ? to see what alternatives are available (in the case of the show command, quite a few!), and then type enough of the parameter to be unambiguous:
router> show in
and it finishes the parameter for you:
router> show interfaces
Only two more key presses and you get a clear explanation of what it's doing. More importantly, your typing errors become much more obvious!
