ruby 1.9 path

[Luis Gomez]

i have installed ruby 1.9.1 but.. when i execute it ... on shell
drdos@drd0s-f00 ~ $ whereis ruby
ruby: /usr/bin/ruby1.9 /usr/lib/ruby


drdos@drd0s-f00 ~ $ ruby
The program 'ruby' is currently not installed. You can install it by
typing:
sudo apt-get install ruby
drdos@drd0s-f00 ~ $


and when i try to go for the path on the system i just get nothing i
have to go CTRL+C or the shell stays like that execution command for
ever:

drdos@drd0s-f00 ~ $ sudo /usr/bin/ruby1.9
^C/usr/bin/ruby1.9: Interrupt
drdos@drd0s-f00

That's just the ruby interpreter waiting for input

drdos@drd0s-f00 ~ $ sudo /usr/bin/ruby1.9
^C/usr/bin/ruby1.9: Interrupt
drdos@drd0s-f00

Try ruby1.9 -e "puts 'hello world'"

Martin yes it did work .

drdos@drd0s-f00 ~ $ ruby1.9 -e "puts 'hello world'"
hello world
drdos@drd0s-f00 ~ $

If this is ubuntu, you should probably do it using
update-alternatives. Check out the other link I posted.
