Building a dynamic UNIX menu with input files

Hi!

I am looking to build dynamic menu (named: lookup.sh) that reads a pipe delimited file for input.

for example, contents of input.txt could be:

Code:

user1|srv1
user3|srv1
user4|srv1
user2|srv2

I want the menu look like:

Code:

1) get password for user1 on srv1
2) get password for user3 on srv1
3) get password for user4 on srv1
4) get password for user2 on srv2
Choose Option:

then if you choose option #1, it would cat pass_user1_srv1.txt to provide the password.

the key thing I am trying to accomplish is that I don't want to modify lookup.sh when i add a new option. i want to go to the input.txt file and add a line to that and it will be read in the next time lookup.sh is run.

will a bash array work? I am not too familiar with them.

Any ideas?
Any help would be greatly appreciated!
Chris
