I was following along Lucas's rubycookbook receipe 15.1 for creating a
ROR application for displaying the o/p of dir command on a windows
machine onoto a browser.

my application is named "check" instead of "status" as given in
receipe.

my C:/Documents and
Settings/ri004902/check/app/controllers/check_controller.rb .. file
looks as
.........................................................
class CheckController < ApplicationController
def index
time = Time.now
@time = time
@dr = exec "dir/p"
end
end
.......................................
and my C:\Documents and
Settings\ri004902\check\app\views\check\index.rhtml .. file is
................................................................
<h1>Directory structure at <%= @time %></h1>
<p><%= @dr %></p>
......................................................

I start the webbrick and point my brwser to
http://localhost:3000/check/

what i get is
Application error (Rails)

I tried with @dr= 'dir/p' in index of CheckController .. but in vain.

could anyone provide me a lead.

Cheers
Rajib

running dir/p), and won't return. Maybe you'd want backticks instead:

Also, I'm not sure whether you mean `dir/p` or `dir /p`. In any event, =

Hope that helps,

This could be irrelevant - I'm on Mac OS X, and there is no "dir"
command there - but OMM the example as printed doesn't work either,
because the single-quotes in the original should be backticks. The
recipe has:

@ps = 'ps aux'

But it should be:

@ps = `ps aux`

Perhaps you should try `dir/p` (whatever that may be) instead of using
exec? Just a guess... m.

Everyone around here pronounces it "cuepon". Sometimes people in
other areas say "koopon".

If such a trivial thing drives him insane, it's a very short ride...

"Absolutely" <= also overused IMHO

There was no mispronounciation of the word. 'Coupon' has two
pronounciations and both of them are perfectly acceptable.

Yes. From Random House Dictionary:

?Pronunciation. COUPON, related to cope and coup, is of French origin. It
has developed an American pronunciation variant (kyoo-pon) with an
unhistorical y-sound not justified by the spelling. This pronunciation is
used by educated speakers and is well-established as perfectly standard,
although it is sometimes criticized. Its development may have been
encouraged by analogy with words like curious, cupid, and cute, where c is
followed by a 'long-u' and the (y) is mandatory.
