get_os_name.lua

by Philippe Fremy

Utility to get the OS name and architecture in pure lua, without any dependency on other modules.

Example on Windows:

c:> lua test_get_os_name.lua
os="Windows" arch="x86"

Example on MacOs X:

$ lua test_get_os_name.lua
os="Mac" arch="x86_64"

Example on Linux:

$ lua test_get_os_name.lua
os="Linux" arch="x86_64"

Heavily based on the following Gist: https://gist.github.com/soulik/82e9d02a818ce12498d1
