Subject: prompt

Is there a Ruby idiom to do prompting? For example,

../rm.rb: remove `t'? y

?

I find it rather troublesome to do that. I have to use something like:

def prompt(file)
   print "#{$0}: remove `#{file}'? "
   decision = STDIN.getc
   STDIN.getc       # Get rid of the ending "\n"
   return decision
end


And it is not that safe in fact. If the user enter "Yes\n", the program will crash.

Can someone suggest a better solution?

Thanks!
