Discovering the OS

Ruby
1

hi list -

just wondering if there is a way to find out which OS ruby is running
on?

for these type of:

if (windows)
system “start file.html”
else if (mac)
system “open file.html”
end

Found this on Google.

It looks like Config::CONFIG[“arch”] is what you need to be looking at.

RUBY_PLATFORM?

RUBY_PLATFORM
The identifier of the platform running this program. This string
is in the same form as the platform identifier used by the GNU
configure utility (which is not a coincidence).

Hm, what about Config::CONFIG[‘target_os’] or Config::CONFIG[‘host_os’]?

Spoilsport. Why’s Ruby always gotta make things easy? -sigh-

Truly, that’s the hardest thing for me to get used to… I’m used to
having to work to find out things like that.
