50.7 How UNIX Systems Remember Their Name

uname
Each computer on a network needs a name. On many UNIX versions, the uname -n command shows you this name. (GNU uname is on the CD-ROM. The install program will only install uname if your system has the facilities to work with it.) On some systems, the command hostname or uuname -l (two us, lowercase L) may be what you want. If you use more than one system, the hostname is great to use in a shell prompt - or any time you forget where you're logged in.
