NAME
     uname -- display information about the system

SYNOPSIS
     uname [-aimnprsv]

DESCRIPTION
     The uname command writes the name of the operating system implementation
     to standard output.  When options are specified, strings representing one
     or more system characteristics are written to standard output.

     The options are as follows:

     -a      Behave as though the options -m, -n, -r, -s, and -v were speci-
	     fied.

     -i      Write the kernel ident to standard output.

     -m      Write the type of the current hardware platform to standard out-
	     put.

     -n      Write the name of the system to standard output.

     -p      Write the type of the machine processor architecture to standard
	     output.

     -r      Write the current release level of the operating system to stan-
	     dard output.

     -s      Write the name of the operating system implementation to standard
	     output.

     -v      Write the version level of this release of the operating system
	     to standard output.

     If the -a flag is specified, or multiple flags are specified, all output
     is written on a single line, separated by spaces.

ENVIRONMENT
     An environment variable composed of the string UNAME_ followed by any
     flag to the uname utility (except for -a) will allow the corresponding
     data to be set to the contents of the environment variable.

     A varsym composed of the string UNAME_ followed by any flag to the uname
     utility (except for -a) will allow the corresponding data to be set from
     the contents of the varsym.  Environment variables override varsyms in
     this case.

EXIT STATUS
     The uname utility exits 0 on success, and >0 if an error occurs.

SEE ALSO
     varsym(1), sysctl(3), uname(3), sysctl(8)

STANDARDS
     The uname command is expected to conform to the IEEE Std 1003.2
     (``POSIX.2'') specification.

HISTORY
     The uname command appeared in PWB UNIX.
