I can do ri upcase to see documentation:

$ ri upcase
...lots of output...

and I should be able to do ri String#upcase, but that gives me:

$ ri String#upcase
Nothing known about String#upcase
$ ri 'String#upcase'
Nothing known about String#upcase
$ ruby -v
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]

Why can't I get String#upcase to work? I would generally like to be able to do ri class#method.

"ri String#upcase" works in Ruby 1.9.3, verified. – Billy Chan Aug 29 '13 at 15:40
sawa, I copied and pasted your command into my shell and got this: `$ ri String#upcase Nothing known about String#upcase durrantm.../ruby$ ruby -v ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux] durrantm.../ruby$ ` – Michael Durrant Aug 29 '13 at 15:46
btw I am on Ubuntu and this is a real issue. Not sure why I'm getting close votes for a real issue I am experiencing :) – Michael Durrant Aug 29 '13 at 15:47
Ubuntu version? I am on 11.10 – Michael Durrant Aug 29 '13 at 15:53
Not working for me, so don't feel bad @MichaelDurrant :) Glad I don't use ri! – Nick Veys Aug 29 '13 at 15:53
Great! not just me! :) – Michael Durrant Aug 29 '13 at 15:53
Nick - are you on Ubuntu 11 or 12? – Michael Durrant Aug 29 '13 at 15:54
Oh, I use 13.04, forgot it. Not 12.10. Doesn't quotes works for you? – Billy Chan Aug 29 '13 at 15:54
No, quotes didn't work for me (either single or double). Maybe it's zsh vs bash? – Michael Durrant Aug 29 '13 at 15:55
installed zsh and that wasn't it. – Michael Durrant Aug 29 '13 at 15:57
Alternatively, ri upcase or ri .upcase – Cary Swoveland Aug 29 '13 at 15:58
So the current candidate for this is being on Ubuntu 11.10 which is probably not the heart of the issue – Michael Durrant Aug 29 '13 at 15:59
Alternatively, keep a console always open when working. Actually I never use `ri` on command line, all on console. – Billy Chan Aug 29 '13 at 15:59
Probably some ri doc is missing. Try the answers here: http://stackoverflow.com/questions/3178900/how-do-i-install-the-ruby-ri-documentation – sawa Aug 29 '13 at 16:04
