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

     -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.
