BASH

Dear all,

Please help/advice - I want to limit user input errors when providing needed information, so I'm trying to write a script that works like a dialog:

Code:

Script asks: Tell me how many hosts you have ?
User answer: 5

Then script should ask user for input and store it into variable/array, depending on how many hosts there are:

Code:

Script: "Please provide host name nr 1:" hostname1 <enter>
Script: "Please provide host name nr 2:" hostname2 <enter>
[...]
Script: "Please provide host name nr 5:" hostname5 <enter>

To ensure that everything is OK, script should print short summary like:

Code:

Script: "OK - you have provided <number of hosts> hosts: <hostname1>, <hostname2>.[...].<hostname5>".

Any ideas ? :-)

Code:

  echo 'Tell me how many hosts you have ?'
  echo -n ' : '
  read COUNTHOSTS

then you need a loop from 0 to $COUNTHOSTS
(check the while sample)

and put them into an array

So I am curious ... you went to google (or your favourite search engine) and typed in 'ask user for input in bash' and 'how to loop in bash' (or similar) and absolutely none
of the replies you looked at could tell you any of this information???

At least try and make some effort.
