Needed help in a ruby script with user interaction involved!

Hi all,

I am struck at this point and needed some help in ruby
I wanted to write a script that accepts the no of VNICs the user wants to create and
then ask for the name of each Vnic he wants
then use these names to create the corresponding Vnics

Eg: suppose that there are 2 Vnics to be created
Then the user should be asked for the names of these and upon entering the names the corresponding ones are created

PS: this is actually a part of the wrapper script that i am struck with!
The command to create the Vnic is already present(in solaris,Crossbow) i just need to know how to include the names provided by the user into the command so that the job is done!

Could anyone please help me
Thanks

This looks like very basic programming and is much more related to Ruby than Solaris. Your question would have a better exposure in the Programming forum but you should at least show a starting piece of code. I'm afraid no one is willing to write this code for you from scratch.

Moreover, someone convinced you to use ruby instead of shell script which would have been the natural choice for this task. Why not asking that person to teach you the ruby basics ?

ok
I did write the code myself(with some quirks)
If its of any help then here it is!!!!

Code:

#!/usr/bin/ruby

class Etherstub
   def initialize
      @estub ; @stub_name
      @vni
   end

def ether_create
    puts "enter the no of stubs you want"
    @estub = gets ;puts "Enter the names 1 by 1 "
    @estub.to_i.each do
         |@stub_name| ;@stub_name = gets
        end
        @estub.to_i.times { puts `/usr/sbin/dladm create-etherstub #{@stub_name}
` }
print "Stub created!!"
end
end

first = Etherstub.new
first.ether_create

The error am getting is that am able to create only one etherstub at a time!
even with the loop!

Finally for you question reagarding shell script or ruby!!
This is choosen to be written in ruby because this will be a wrapper that will use the underlying commands and there are a few more reasons.....

Anyway i will try my luck in the programming forum!!!
Thanks
