How to evoke Ruby?


My OS is Linux Mint 17.3 Rosa Cinnamon. The computer tells me that I already have the Ruby interpreter version 1.9.1 or perhaps version 1.9.3 installed.

But I cannot see how to start it running. It is not to be found anywhere in the desktop menu. When I type in 'ruby' in the console and press return, I just get a new blank line. When I then type in for example '2 + 2' and press return, I get another new blank line.

Thanks.

In the console I typed in 'ruby' return, then typed in '2+2=' return and it responded:

"-:1: syntax error, unexpected '=', expecting $end"

So is that Ruby?

Thanks.

Edit/update: a web-search indicates that it is indeed Ruby.

Is is customary to use an IDE for Ruby? Which is the most popular one for Ruby when using Linux? Thanks again.

yes, that is ruby.
you might want to start here: https://www.tutorialspoint.com/ruby/index.htm, or here: https://www.ruby-lang.org/en/documentation/quickstart/

Thanks.

It seems to be better to type 'irb' in the console rather than 'ruby'.

This https://www.ruby-lang.org/en/documentation/quickstart/ gives a 20 minute introduction to Ruby.
