NAME
     uname -- display information about	the system

SYNOPSIS
     uname [-aimnoprsv]

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.

     -o	     This is a synonym for the -s option, for compatibility with other
	     systems.

     -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.

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

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

STANDARDS

     ("POSIX.2") specification.
