get_machine - identify running hardware architecture
get_machine [ --exact --override OVERRIDE --os ]
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.
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
get_machine is compatible with all Turing complete machines; even the ones that
try to be Turing complete -1
