uname(1)              UNIX System V(Essential Utilities)               uname(1)


NAME
      uname - print name of current UNIX system

SYNOPSIS
      uname [ -amnprsv ]
      uname [ -S nodename ]

DESCRIPTION
      uname prints the current system name of the UNIX system to standard
      output.  It is mainly useful to determine which system one is using.  The
      options cause selected information returned by uname(2) and/or sysinfo(2)
      to be printed:

      -a    Print all information.  Output will in the following order:
            systemname   nodename   release   version   machine   hostprocessor

      -m    Print the machine hardware name (machine).

      -n    Print the nodename (the nodename is the name by which the system is
            known to a communications network).

      -p    Print the current host's processor type (hostprocessor).

      -r    Print the operating system release (release).

      -s    Print the name of the operating system (systemname) (for example,
            UNIX System V).  This is the default.

      -v    Print the operating system version (version).

      -S    Change nodename (see -n option above).  nodename is restricted to
            SYSNMLN characters.  SYSNMLN is an implementation specific value
            defined in sys/utsname.h.  Only a privileged user is allowed this
            capability.

            For computers based on Intel microprocessors, using the -S option
            also changes the name of the operating system (systemname).

NOTES
      The output of uname is affected by the environment variable SCOMPAT.
      SCOMPAT is part of the application compatibility features provided to
      support UNIX applications other than UNIX System V Release 4.
