Hi, let me compare with an alternate METHOD 2 that I usually apply to get the list of (all?) installed packages:

METHOD 2:
dpkg -l | grep '^ii | awk ' { print $2 } ' | awk -F':' ' {print $1 } ' | sort > INSTALLED_DPKG.txt

Comment:
The 2nd awk is to remove architecture additions such as ‘:amd64’.

1 vs. 2:
In my case of antiX-21 install set to testing, the record count is the following: @rokytnji (METHOD 1) = 842, (METHOD 2) = 2001.
There is a multiplicity in method 2, e.g. consider the ‘audacious’ package(s).
Only the single package ‘audacious’ is listed in method 1 but additional are listed in method 2, e.g. ‘audacious-plugins’.
This is because the command ‘apt-mark showmanual’ ignores automatic dependencies/additions from the list of installed packages.

The method 1 is probably better suited if you wish to list installed packages as a backup information before performing an upgrade.
The automatically installed (depedencies) won’t be included and hence the list will be shorter and easier to modify later.

I noticed that the Method 1 does no longer apply to my antiX-21 (repositories set to testing) because the directory ‘/var/log/installer/’ is no longer present.

Also, the command for Method 2 contained a typo, missing closing tick “‘” in the grep, the fixed version is:
dpkg -l | grep '^ii' | awk ' { print $2 } ' | awk -F':' ' {print $1 } ' | sort > INSTALLED_DPKG.txt

What is the intent of the aforementioned scripts?

I am curious. Not criticizing.

To get a list of all installed packages, I keep it simple and use:

sudo apt list --installed

If the package name is only desired:

sudo apt list --installed | awk -F "/" '{print $1}'

techore, those commands [[[ I would not call them “scripts” ]]] intend to deduct from the list all packages that were, already, present when the system was initially installed. Just show package which have been installed after-the-fact.

On antix live system, it has this similar file /usr/share/antiX/installed-packages.txt
a list of already pre-installed packages that were used to build out the live system iso.

Why does someone care to know which packages have been installed after-the-fact? I can think of several reasons, reasons beyond just sheer curiosity.

Why you may want to know which packages were added (or are currently installed)?

I mantain a manual list of packages I have installed (e.g. console-based ‘sudoku’ package, favorite alternate players/browsers and codecs) so that I can easily bring all (or most of) the stuff to any new (re-)installation.
I simply copy-paste the package list from such a file to terminal ‘sudo apt install …’ and I once I transfer backup/copy of configuration from ‘/home/$(whoami)/’, the newly installed system is adjusted to my liking much faster.

If you do not keep the file, the above is a way to produce corresponding list of additional/all packages.

I do the same thing too to what @sybok described in the above quote. It saves me a lot of time. Another thing I do is take periodic iso snapshots of my installed system. It is nice to know others are doing similar things.

I just like the easy to read readout.

Here is my MX Fluxbox install.

Like I did not know MX carries cli-aptix out of the box because I did not install it.
