NAME
     uname - display information about the system

SYNOPSIS
     uname [-amnrsv]

DESCRIPTION
     The uname command writes various system-identifying attributes to stan-
     dard output.  By default, uname writes the name of the operating system.

     The options are as follows:

     -a      Behave as though all the other options were specified.

     -m      Print the name of the current hardware platform (the machine or
             CPU type).

     -n      Print the ``node name'' (the host name).

     -r      Print the current release level of the operating system.

     -s      Print the name of the operating system implementation.

     -v      Print the version string for this release of the operating sys-
             tem.  This may contain embedded blanks.

     When more than one item is printed, the order used is operating system
     name, node name, release, version number, and machine type, and all out-
     put is written on a single line, separated by spaces.

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