Can anyone tell me how I can figure out from Ruby what platform I'm
running on? My Ruby program needs to know whether it's running on
linux, cygwin, windows etc...

RUBY_PLATFORM

It's not perfect, but it's a good guess.

Use RUBY_PLATFORM or rbconfig.rb

$ irb
irb(main):001:0> RUBY_PLATFORM
=> "powerpc-darwin7.6.0"
irb(main):002:0>

Cheers,

For more detailed information, there is sys-uname. Available on the
RAA. Yes, it works on Windows, too. :)

And there's always the quick-and-dirty approach that has been mentioned
before, to differentiate between windows and everything else:

if File::ALT_SEPARATOR
puts "I'm on windows!"
else
puts "I'm not on windows!"
end
