NAME

     uname -- Print operating system name

SYNOPSIS

     uname [-amnprsv]

DESCRIPTION

     The uname utility writes symbols representing one or more system characteristics to the standard output.

     The following options are available:

     -a      Behave as though all of the options -mnrsv were specified.

     -m      print the machine hardware name.

     -n      print the nodename (the nodename may be a name that the system is known by to a communications network).

     -p      print the machine processor architecture name.

     -r      print the operating system release.

     -s      print the operating system name.

     -v      print the operating system version.

     If no options are specified, uname prints the operating system name as if the -s option had been specified.

STANDARDS

     The uname utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').	The -p option is an extension to the standard.

NAME

     uname -- display information about the system

SYNOPSIS

     uname [-aiKmnoprsUv]

DESCRIPTION

     The uname command writes the name of the operating system implementation to standard output.  When options are specified, strings represent-
     ing 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.

     -i      Write the kernel ident to standard output.

     -K      Write the FreeBSD version of the kernel.

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

     -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 standard output.

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

     -U      Write the FreeBSD version of the user environment.

     -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.

     The -K and -U flags are intended to be used for fine grain differentiation of incremental FreeBSD development and user visible changes.

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.

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.

     The -K and -U extension flags appeared in FreeBSD 10.0.
