Top Forums UNIX for Beginners Questions & Answers Passing input to script using another script Post 302987944 by jim mcnamara on Sunday 18th of December 2016 11:55:06 PM

You are saying the answers are always the same. And you do not want to hard code them in the script because it may need to change someday.

You can use a here document:
Assume your script is named script.sh
Code:
#!/bin/bash
# example here document
./script.sh << EOF
comment, comment, comment 
`date`
1
EOF

The stuff between the EOF words is what would be typed on the keyboard.
EOF can be any combination of symbols that are not any valid UNIX or shell keyword or command.
Example -
Code:
myprog << !
stuff
!

! is not any valid keyword or command

NOTE: !! the EOF or whatever you use must match exactly on the first line and the end. Plus the last EOF has to be in column 1 - the leftmost column.
If you want to have the last EOF somewhere for easier reading use a dash (red so you see it) on line #1 before the EOF or ! or whatever.
Code:
myprog <<-EOF
stuff
       EOF

You absolutely cannot stick random "EOF" some place else in the code, other than where the true end is, when you do this. It will be treated as the end and you will get errors.

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.
