I am trying to set up an automatic execution of a java package which
accepts values from a number of prompts.

For instance,

The execution line is as follows:

[abc] ~/dfg > java -jar abc.jar

Platform Options Available:
[1] Windows
[2] Unix

Choose: 2

Database
[1] Oracle
[2] UDB

Choose: 1

etc...

How do I automatically run this using ksh without user input?

Thanks in advance

If it reads from the standard input:

printf "%s\n" 2 1 | java -jar abc.jar

If not, you can use 'expect'.

Thanks for your help.

I have used expect, but it doesn't seem to work. Perhaps I code it
wrong. Here is the code

#!/usr/bin/expect
java -jar abc.jar
expect ".*"
send "2\r"
expect eof

Never mind. My mistake.

I didn't use spawn.
