NAME
     uname -- display information about the system

SYNOPSIS
     uname [-amnprsv]

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 specified.

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

     -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 standard
	     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.

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

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.

SEE ALSO

     specification.
