Command line

[Rong]

Please forgive this stupid newb question but I thought it was possible
to send a command to the ruby interpreter without using IRB.
ruby puts "hello"

This command just returns an error that there is no file or directory
called hello.
Running Ruby 1.9.1



Help please.

ruby --help

There is nothing in ruby --help to answer my question.

Thank you. I did not understand that the entire command had to be
quoted.

Are you sure?

' -e 'command' one line of script. Several -e's allowed. Omit [programfile]'

There is.

Maybe you should narrow the field a bit:

$ ruby --help | grep command

-s

You could always just use an IDE like NetBeans: http://www.netbeans.org/

You could always just learn the API.

Was that intended as an insult? I was merely trying to help the best
way I knew how. I don't use the command line. I think it takes too
long.

It seems a lot of us use command line Ruby because they consider it
*faster*. I guess Greg considered it a bit too heavy weight to
use an IDE for "hello". Btw, the OP specifically asked how to make
Ruby print "hello" from the command line - so "use an IDE" is not
exactly an answer to _that_ question.

Kind regards
