Hi!

IMHO if you could use bash instead of sh, there would be a trivial solution using select instead of case:

Code:
#!/bin/bash
INSTANCE=""
while [[ $INSTANCE = "" ]]; do
    echo "DB2 INSTANCE PROFILER UTILITY"
    echo "Please enter the number of the instance you want to profile:"
    select INSTANCE in $(db2ilist); do
         if [[ $INSTANCE = "" ]]; then
              echo "Please enter a valid number. Retry."
         else {
              . /dbhome/${INSTANCE}/sqllib/db2profile
              db2 get instance; }
          fi
          break
          done
     done
exit 0

I don't think it's possible to do it dinamically with case.

       [--passwordfile filename] [--secure|-s]

       Use the list-instances to list all the instance in the server. The list-instances command can be run both locally and  remotely.   To  list
       remote  instances,  the named administration server must be running on the hostname and port number specified. The user authenticates using
       the password identified for the administration server.

OPTIONS

       --user		       administrative user associated for the instanace.

       --password	       administrative password corresponding to the administrative user.

       --port		       port number associated with the administrative host.

       --domain 	       name of the domain.

       --local		       determines if the command should delegate the request to administrative instance or run locally.

       --passwordfile	       file containing passwords appropriate for the command (e.g., administrative instance).

       --secure 	       if true, uses SSL/TLS to communicate with the administrative instance.

       Example 1: Using list-instances in local mode

       asadmin> list-instances --domain1 --local
       admin-server running
       server1 running

       Where: the server1 and admin-server instances for the domain1 domain is listed.

       Example 2: Using list-instances in remote mode

       asadmin> list-instances --user admin --passwordfile passwords.txt --host localhost --port 4848
       server1 [mayank:80] running

       Where: the server1 instance associated with the specified user, passwords, host, and  port  number  specified  is  listed  for  the  remote
