NAME

       get_machine - identify running hardware architecture

SYNOPSIS

       get_machine [ --exact --override OVERRIDE --os ]

DESCRIPTION

       get_machine exists to make simple shell scripts that need to know that hardware architecture it is
       assuming or what host operating system is being used.

       At its core is figure out the general hardware architecture and return it as quickly as possible.
       Although it is sometimes useful to return something different; which is why --override exists and thus
       what ever is supplied by with it is returned.  Scripts that wish to expose that can leverage the
       environment variable GET_MACHINE_FLAGS to allow efficient overriding in their scripts. Or if they wish to
       only override what Operating system is running the environment variable GET_MACHINE_OS_FLAGS should be
       used.
       If one wishes for something more exact than x86 or amd64, the option --exact will return more specific
       values like i686-pae.
       Should one desire to know the host operating system: --os
       A word of warning; --override always will take top precedence and can return anything you desire.

EXAMPLES

       Typically, get_machine will be in scripts used in bootstrapping
       # get_machine
       # get_machine --override "I am the very model of a modern major general"
       # get_machine ${GET_MACHINE_FLAGS}
       # get_machine ${GET_MACHINE_OS_FLAGS} --os

COMPATIBILITY

       get_machine is compatible with all Turing complete machines; even the ones that try to be Turing complete
