uname(1)							      uname(1)

       uname  - display information about computer system; set node name (sys‐
       tem name)


       In the first form above,	 the  command  displays	 selected  information
       about  the  current  computer  system,  derived from the structure (see

       In the second form, sets the node name (system name) that  is  used  in
       the structure.

       recognizes the options listed below.  If you enter several options, the
       output is always in the order shown for the option.

	      none	     Equivalent to

	      Display the options below in the following order,	 separated  by

	      Display the machine identification number
			     (or  the node name, if the machine identification
			     number cannot be determined).  This option cannot
			     display the unique machine identification number.
			     For getting  the  unique  machine	identification
			     number  refer  to	the command or call.  See get‐
			     conf(1)) and confstr(3C).

	      Display the license level of the operating system.
			     128-, 256-, and unlimited-user licenses are shown

	      Display the machine hardware and model names.
			     On	 Itanium(R)-based  systems, this option always
			     displays See

	      Display the node name (system name)
			     by which the system is usually known  in  a  UUCP
			     network.  See

	      Display the current release level of the operating system.

	      Display the name of the operating system.
			     On	 standard  HP-UX  systems,  this option always

	      Display the current version level of the operating system.

	      Change the node name (system name) to
			     nodename.	nodename is restricted	to  characters
			     (see  uname(2)).  See Only users with appropriate
			     privileges can use the option.

       When you execute the command it produces output like the following:

       The displayed fields are interpreted as follows:

	      The operating system name (option

	      The UUCP network system name by which the system is known

	      The operating system release identifier

	      The operating system version identifier

	      The machine and model numbers

	      The machine identification number

	      The operating system license level

       It is recommended that the command or the command be used to obtain the
       model  name,  since  future  model names may not be compatible with See
       model(1) and getconf(1).

       Many types of networking services are supported on HP-UX, each of which
       uses  a	separately  assigned  system  name  and naming convention.  To
       ensure predictable system behavior, it is essential that	 system	 names
       (also  called  host  names  or node names) be assigned in such a manner
       that they do not create conflicts when the various  networking  facili‐
       ties interact with each other.

       The  system  does  not rely on a single system name in a specific loca‐
       tion, partly because different services use dissimilar name formats  as
       explained below.	 The and commands assign system names as follows:

       |Node Name     |Command	     |name Format    |Used By		     |
       |Internet name |hostname name |sys[.x.y.z...] |ARPA and NFS Services  |
       |UUCP name     |uname -S name |sys	     |uucp, related programs |
       +--------------+--------------+---------------+-------- --------------+

       where  sys represents the assigned system name.	It is recommended that
       sys be identical for all commands and locations and that	 the  optional
       follow the specified notation for the particular ARPA/NFS environment.

       Internet	 names	are  also frequently called host names or domain names
       (which are different from NFS domain names).  Refer to hostname(5)  for
       more information about Internet naming conventions.

       Whenever the system name is changed in any file or by the use of any of
       the above commands, it should also be changed in all other locations as
       well.   Other  files or commands in addition to those above (such as if
       used to circumvent for example) may contain or alter system names.   To
       ensure correct operation, they should also use the same system name.

       System  names  are  normally  assigned  by  the script at start-up, and
       should not be altered elsewhere.

       Setting a nodename of more than 8  bytes	 is  possible  only  with  the
       appropriate  configuration options enabled.  It is strongly recommended
       that all related documentation be completely understood before  setting
       a  larger  node name.  A node name larger than 8 bytes can cause anoma‐
       lous or incorrect behavior in applications which use the command or the
       system function to access the name.
