What is the Terminal command to show the K ?

K means the installed iso was:
Kubuntu 22.04 not
ubuntu 22.04


Command 1:
lsb_release -ds

Ubuntu 22.04.1 LTS


Command 2:
lsb_release -ds |tr '\n' ' ' ; cat /etc/os-release | grep -i --color=always 'version=' | awk '{print $3 " "$4}' |tr '"' ' ' ;

Ubuntu 22.04.1 LTS (Jammy Jellyfish)


What is the Terminal command to show the K ?
K as in the Operating System is :
Kubuntu 22.04.1 LTS (Jammy Jellyfish)

The OS is Ubuntu. The DE (Desktop Environment) is KDE Plasma.

Ok.


plasmashell --version
above in Terminal shows :

plasmashell 5.24.6


What is the Terminal command to show K?
Kubuntu ... Desktop Environment
or
K _ something

To show K.......what?
Plasma is the desktop environment so plasmashell --version is correct, as you see.

Kubuntu needs to have these report as Ubuntu, as quite a lot of things that depend on being reported (correctly) as ubuntu would break otherwise.
Kubuntu is NOT really a separate distro from Ubuntu

HOWEVER, look at tools like neofetch for all the cool details that show the K


I can't off the top of my head recall exactly where tools like neofetch on the command line and KInfoCenter get the specifics that show Kubuntu,. but it should be easy to discover, I think.
Edit:
Actually, in if I am reading it correctly, on Ubuntu neofetch looks for the presence of desktop-specific directories in /etc/xdg/ to determine which Flavour it is, so there being a 'plasma-something-or-other' there sets it to Kubuntu

Are you trying to do something like this?

awk -F" " 'BEGIN {printf "K"}{ printf tolower ($1) " " ($2)}' /etc/issue

EDIT: Corrected the code a little

[joseph22]

Are you trying to do something like this?

awk -F" " 'BEGIN {printf "K"}{ printf tolower ($1) " " ($2)}' /etc/issue

above result is
Kubuntu 22.04.1

Yes the above is a desired result but,
No it is not desired because it appears a K was manually inserted.

Manually inserting a K is not desired.
Like manually inserting a K with

echo "K" |tr '\n' '\000' ; lsb_release -ds

KUbuntu 22.04.1 LTS


i was looking for a native command that
would interrogate the computer and show something like:
K_
K_desktop_envoronment
K_something

said differently
Looking for a command that
interrogates the computer and reflects the fact
that the install comes from the iso:

kubuntu-22.04.1-desktop-amd64.iso
3.4 GiB (3,674,746,880) bytes

meaning computer is running
kubuntu-22.04.1 not
ubuntu-22.04.1

[claydoh]

That will be hard, as kubuntu=ubuntu as an OS. If the OS level marking say 'kubuntu' instead of 'ubuntu' there are many things that can break
Kubuntu is not a separate, unique OS or distro.

This is how neoftech discovers if it is Kubuntu or Xubuntu, etc:

# Get Ubuntu flavor.
if [[ $distro == "Ubuntu"* ]]; then
case $XDG_CONFIG_DIRS in
*"studio"*) distro=${distro/Ubuntu/Ubuntu Studio} ;;
*"plasma"*) distro=${distro/Ubuntu/Kubuntu} ;;
*"mate"*) distro=${distro/Ubuntu/Ubuntu MATE} ;;
*"xubuntu"*) distro=${distro/Ubuntu/Xubuntu} ;;
*"Lubuntu"*) distro=${distro/Ubuntu/Lubuntu} ;;
*"budgie"*) distro=${distro/Ubuntu/Ubuntu Budgie} ;;
*"cinnamon"*) distro=${distro/Ubuntu/Ubuntu Cinnamon} ;;
esac
fi​

$XDG_CONFIG_DIRS would be /etc/xdg
The presence of the dir or file containing 'plasma' tells the neofetch script to show Kubuntu.

You might look and see if the file /etc/issue or /etc/issue/net mention Kubuntu. but they probably all say Ubuntu.
There is no 'kubuntu' until you get to the login screen, and still, the OS remains Ubuntu, of course.



Aaaaaaactually......kinfocenter uses something to show Kubuntu and not Ubuntu, so Kubuntu adds something somewhere for that application to read this info

/etc/xdg/kcm-about-distrorc <----- Bingo!
But there is no special command, just need to create a basic script to read that line. that shows Kubuntu.

/etc/xdg/kcm-about-distro <----- Bingo!
But there is no special command, just need to create a basic script to read that line. that shows Kubuntu.

This computer has no such file:
/etc/xdg/kcm-about-distro

Computer has:
/etc/xdg/kshorturifilterrc
or
said differently, computer has:
/media/X/4eb08847-7b1a-4aa2-b27f-5bdae96ae4ab/etc/xdg/kshorturifilterrc

Computer has:
kcm-driver-manager.mo
kcm-whoopsie.mo


Question:
What other file shows Kubuntu and not Ubuntu?

[claydoh]

That's odd as my 22.04, 20 04 and Neon installs have this file, as do most distros generally iirc

I did have a minor typo. It will be kcm-about-distrorc.

desired result

Kubuntu 22.04.1 LTS (Jammy Jellyfish)



double space after Kubuntu indicates a construct, not 1 command:

[joseph22]

/etc/xdg/kcm-about-distrorc

more precision, file location ...
How to show Device Path, Parent folder, file:
kcm-about-distrorc

filez=/etc/xdg/kcm-about-distrorc && \
df $filez | \
grep dev | awk -v var=$filez '{print $1 var}'

/dev/nvme0n1p3/etc/xdg/kcm-about-distrorc

[claydoh]

/etc/xdg/kcm-about-distrorc is the correct, precise path.

The device (/dev/<whatever>/) is completely irrelevant here, as this will be completely different for each computer, depending on one's specific drive types, partition schemes, and OS layouts.
