Get system name

[Kless]

Is there any method that returns the operating sytem being used?

Check out the Ruby Constants... PLATFORM could be one.

Check out the Ruby Constants... PLATFORM could be one.

The constant is RUBY_PLATFORM.

If more info is needed, check the output of this,

require 'rbconfig'
require 'pp'
pp Config::CONFIG

That's a great alias! I wish I'd thought of it.
Now someone unsubscribe me from this list, dammit. I can't figure out how,
cause I'm a moron!

(Just kidding, don't really unsub me...)

I haven't that constant, but 'target_os'.

RUBY_PLATFORM is a top-level constant, apart from Config::CONFIG.

$ ruby -e 'p RUBY_PLATFORM'

The constant is RUBY_PLATFORM.

I recommend against this because of JRuby (and probably IronRuby).
JRuby, for example, will return "java" for RUBY_PLATFORM.

If more info is needed, check the output of this,

require 'rbconfig'
require 'pp'
pp Config::CONFIG

There you go. Take a look at Config['host_os'].

I wonder if RUBY_PLATFORM should be deprecated, then?

I've used 'target_os' in the past, a decision I rationalized thusly: on
the off chance that ruby spits out an executable of any form, I want the
platform of that executable. In hindsight I wonder if it makes any
sense.

Is there an example of CONFIG["target_os"] != CONFIG["host_os"] ?

Yes, my Ubuntu shows:

$ ruby -e 'require "rbconfig"; p Config::CONFIG["host_os"],
Config::CONFIG["target_os"]'
