Your exit &v_count statement needs to at least be run before the EOF closes the here document else this is left to the shell. It will run the shell exit in the background and then try to run the command v_count, which probably won't be found. It will then confuse you.

I agree with Peasant that this probably isn't the way to go for non-trivial counts. Some shells might let you get away with it, but best to avoid it. Perhaps an SQL statement like prompt "v_count=&v_count" ; might work, but I haven't got a server I can test this statement on at all, so it will probably have an error in it, however if you can generate an obviously tagged output that tell you the value you need to pass, then perhaps you can get at that in the shell script part.

Maybe someone else can jump in here to suggest a clean way to pass the value out. I've got a few options but I'd expect better ones. Given you are writing all the output to a log file, you might get away with:-
Code:
:
:
EOF

v_count_line="$(grep 'v_count='  "${LOG_TEXT}")"            # Grab the crafted line from the output file

v_count="${v_count_line#*=}"          # Set the value in the shell script to be the part of the line after the equals sign by trimming off everything in front (including the equals sign)

printf "The duplicate lines count is %s\n" "${v_count}"
:
:

Like I say, there's probably a better way.

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

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.
