and report back how far it gets you...
hello firstly thanks for the time.

Yes this is exactly what I am looking for but the generated hash values do not match in the above output for example the first row
Code:
10|ABC|30|M|ID,NAME|f2e88b4a581adf6c7833d95799b7a08c

the hash value is f2e88b4a581adf6c7833d95799b7a08c but here I am expecting output hash value as 73aca49763216fb96bbc2acef7b60afb i.e

Code:
10|ABC|30|M|ID,NAME|73aca49763216fb96bbc2acef7b60afb

the way i arrived to this value is

echo -n '10,abc'|md5sum and this returns me 73aca49763216fb96bbc2acef7b60afb

thanks

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.
