Comparing content of two variables
I have very abstract need of "comparing two variables" and take subsequent actions.
please refer to image below
I have a part of script which reads a file and generates variables based on content of this file.(Variables generated in same shell)
The reason i have categorized the design in user and script environment is that the script environment must be able to handle changes made in user environment.
The changes will only be in the form of new line entries in file1.txt
I need help on how to move from
desired output to final output

devscripts.conf
DEVSCRIPTS.CONF(5) File Formats Manual DEVSCRIPTS.CONF(5)
NAME
devscripts.conf - configuration file for the devscripts package
DESCRIPTION
The devscripts package provides a collection of scripts which may be of use to Debian developers and others wishing to build Debian pack-
ages. Many of these have options which can be configured on a system-wide and per-user basis.
Every script in the devscripts package which makes use of values from these configuration files describes the specific settings recognised
in its own manpage. (For a list of the scripts, either see /usr/share/doc/devscripts/README.gz or look at the output of dpkg -L devscripts
| grep /usr/bin.)
The two configuration files are /etc/devscripts.conf for system-wide defaults and ~/.devscripts for per-user settings. They are written
with bash(1) syntax, but should only have comments and simple variable assignments in them; they are both sourced (if present) by many of
the devscripts scripts. Variables corresponding to simple switches should have one of the values yes and no; any other setting is regarded
as equivalent to the default setting.
All variable names are written in uppercase, and begin with the script name. Package-wide variables begin with "DEVSCRIPTS", and are
listed below, as well as in the relevant manpages.
For a list of all of the available options variables, along with their default settings, see the example configuration file
/usr/share/doc/devscripts/devscripts.conf.ex. This is copied to /etc/devscripts.conf when the devscripts package is first installed.
Information about configuration options introduced in newer versions of the package will be appended to /etc/devscripts.conf when the pack-
age is upgraded.
Every script which reads the configuration files can be forced to ignore them by using --no-conf as the first command-line option.
PACKAGE-WIDE VARIABLES
The currently recognised package-wide variables are:
DEVSCRIPTS_CHECK_DIRNAME_LEVEL, DEVSCRIPTS_CHECK_DIRNAME_REGEX
These variables control scripts which change directory to find a debian/changelog file or suchlike, and some other miscellaneous
cases. In order to prevent unwanted, even possibly dangerous, behaviour, these variables control when actions will be performed.
The scripts which currently make use of these variables are: debc, debchange/dch, debclean, debi, debrelease, debuild and uscan, but
this list may change with time (and I may not remember to update this manpage). Please see the manpages of individual scripts for
details of the specific behaviour for each script.
