Shell Programming and Scripting

Hi All,

I have a script Abc . This is has only the privilege of execution. I cannot see the code. When I run the script "Abc" , It display set of name in an random order with a number 1.e
1 James
2 john
3 jack
4 neil
5 bob

If my name is neil , I am expected to type 4 and press enter
Now it displays months in random order. I am expected to enter the month in which I was born.

i.e
1 March
2 Jan
3 Feb
4 August
5 sep
.
.
.
....


Now let say I enter 4
My verification will be complete.


Is there a way were I can write an script to call abc and give the input as neil and august so that I don have to go through this manual process.



Ps: The example I have given above is just an paradigm to the problem I have for easy understanding. The real problem is similar.

Code:

./script <<EOF
4
4
EOF

@Corona688 ur answer is applicable when I know that it is 4 , 4. But thats not the case. They change the order everyday. Name will remain same , Month will remain same but not the order . i.e. Neil can appear in 4th position today so i enter 4. Tomorrow it might be at position 6 in which case i have to enter 6

Any input from user who have experience or explored a similar type of issue.?

If the input is variable then it's not hard-coded.

You'll need to read the output from the script to determine the correct input.

For a start, its not a script but quite surely a binary... type

Code:

 file abc

If it is done in such a way, I suppose it is for security purpose for we (you also..) don't know what else it is doing ( and you haven't said anything about it either...)...
The way you wrote your question and with the information you gave, the immediate answer that comes to mind is : Simple! Don't call it...
If we knew a bit more perhaps the answer would be different, but then, we are not a hacking forum and don't like messing up what others put in place for security unless there is a very good reason.

Something that changes isn't hardcoded...

You could try the expect language. It's built for dealing with program interfaces.
