Bash shell scripting doubt
Hello All,

I am setting up a cron job, where i am calling a shell script to make few builds. I got struck at a point, need some expert inputs to proceed further.

The script is categorized in 5 parts and in the last part while building software it asks for few questions like:-

1. Build mode choice
2. normal build
3. Copy Images
4. Arch

User manually has to input ans for these questions:-
1
yes
n
64


The ans's are fixed and this won't change. How shall i hard-code them or do something in the script so as when script flow reaches to this point it automatically take's these value.

So far the cron job is not getting completed as it's waiting for user to key in these values manually....



I had faced similar issue while building kernel modules but there it was easier as i had to take default values always:-

yes '' | make kernel
//this worked.


But in the current scenario i need to input values......


Any inputs??

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
