What can be the problem?

I continue to pursue ways to do everything from the command line and while it does not seem common whatsoever I am curious if there is one single example of a command line tool that allowed someone to purchase something over the internet, make a payment, and expect the delivery of said good. Not using a terminal browser on a website or something, but an actual command line application. Thank you.

Looking for a private journal app that is customizable in font size and style and similar functions to Libra writer. Why you ask? *I am a Tinkerer, and a Philosopher of sorts, and am looking for that **"just right"** packaged app that meets these primary specs:* Encrypted, Secure, in Ubuntu or Debian, and similarly customizable to Libra Writer as far as fonts and text size and shapes goes, and also contains a simplistic toolbar for object creation with various geometric shapes and sized objects for point & click ease. Also a simple header or title block creator to start each new thought or idea would be fantastic! Also, I am somewhat new to Linux & Unix, and any terminal command line syntax to simplify installation or functionality and ways to encrypt is greatly appreciated! Thank you kindly as well, Rudy

Don't set wm_class of "Navigator" when starting Firefox

I'm starting Firefox as follows:
/usr/bin/firefox --no-remote -P Fastmail --class "FastmailFF"
The ultimate goal is to figure out a command to put in a .desktop file which will have it's own icon and exist separately to the normal browser. The above gets grouped under the current Firefox icon. When I inspect the window using xprop WM_CLASS command, I get the following back for the above:
WM_CLASS(STRING) = "Navigator", "FastmailFF"
and the following for the main Firefox:
WM_CLASS(STRING) = "Navigator", "firefox"
So I figure the common "Navigator" string is causing the grouping. Is there a way to prevent Navigator getting added upon startup? It looks like firefox is installed via a snap:
Version: 1:1snap1-0ubuntu2

I'm launching Battle.net with https://usebottles.com/ , and it creates two windows: one for the launcher itself, and one for the game. Both windows are missing an icon and show "steam_proton" mouseover tooltip. enter image description here I know I can control appearance of application menu items with StartupWMClass property, but both these windows have the same WM_CLASS of steam_proton, so I can't do that. What's different for these windows, is WM_NAME and WM_ICON_NAME properties, but GNOME seems to ignore those. Is there any way I can make GNOME use them?

I have two identical systems running both debian bullseye with gnome3 (3.38.5) and I wanted to add bettebird as my default application for mails. I've created a desktop file in ~/.local/share/applications on system 1 and everything works fine on system 1 - I can select betterbird as the default mail program... I've copied this file to system 2 and betterbird does show up in the activities overview, however, in the 'default application' settings it's not visible. I'm really puzzled & running out of ideas how I can fix this. What I checked/tried after googling for a long time but no success: - Icon & Exec are correct (I can start Betterbird from activities menu) - I have other custom desktop files in ~/.local/share/applications/ and they do work - I changed rights from 644 to 755 (though other desktop files in ~/.local/share/applications do have 644 and do work...) -> no luck of course - I copied thunderbird.desktop from /usr/share/applications to my local folder & adapted entries/renamed file accordingly -> no luck - I tried to open a file with betterbird from my file explorer (nautilus) but Betterbird is also not available from the application list Any ideas how to proceed?

How to see what statement (memory address) my program is currently running: the program counter register, through Linux commands?

What's the command I should execute to know it?

I am a new developer and I have recently noticed that several applications do not officially support Linux desktop apps. However, I've seen developers create their own open-source unofficial versions of these apps, and they perform almost as well as the native apps on Windows or Mac. These applications also work with the specific service's account. I am interested in creating some of these unofficial apps for Linux. During my research online, I didn't find a lot of answers specific to creating unofficial apps for services that already exist. Most resources I found were about creating your own app from scratch. I am looking for guidance on how to create unofficial versions of existing services. For example, I came across these unofficial apps that caught my interest: 1. WALC: An unofficial WhatsApp client for Linux (https://github.com/WAClient/WALC) 2. Notion Reborn: An unofficial Notion.so client for Linux (https://snapcraft.io/notion-snap-reborn) I would like to understand the process of creating such apps. What are the legal implications? What technologies are generally used? How do these apps interact with the official services? Any guidance, resources, or advice would be greatly appreciated. Thank you!

How to reliably determine the name of an application for use in Gnome: Favorite Applications?
I have ran the following command to setup my Favorite Applications menu: ``` gsettings set org.gnome.shell favorite-apps "[ \ 'docker-desktop.desktop', \ 'org.gnome.Nautilus.desktop', \ 'firefox-esr.desktop', \ 'github-desktop.desktop', \ 'gnome-system-monitor.desktop', \ 'org.gnome.Terminal.desktop...
I have ran the following command to setup my Favorite Applications menu:
gsettings set org.gnome.shell favorite-apps "[ \
	'docker-desktop.desktop', \
	'org.gnome.Nautilus.desktop', \
	'firefox-esr.desktop', \
	'github-desktop.desktop', \
	'gnome-system-monitor.desktop', \
	'org.gnome.Terminal.desktop', \
	'gnome-tweaks.desktop' \
]"
This is working perfectly (after working out the precise application names). However I can't work out what the application name is for gnome-control-center - I have tried all of these:
'gnome-control-center', \
	'gnome-control-center.desktop', \
	'gnome-controlcenter.desktop', \
	'gnome.control-center.desktop', \
	'org.gnome-control-center.desktop', \
	'org.gnome.control-center.desktop', \
	'org.gnome.controlcenter.desktop', \
	'/usr/bin/gnome-control-center', \
	'/usr/bin/gnome-control-center.desktop', \
None of them work. "Settings" (A.K.A. Control Center) does not show in my list of Favorite Applications. How can I add it to my menu please? Do I have the application name wrong? I am able to successfully launch it from the Terminal using both gnome-control-center and /usr/bin/gnome-control-center I am also looking for the name of the Text Editor (gnome-text-editor) application - as I can't work that one out either, to add it to my Favorites. How can we reliably determine the name of each application please? I am running Gnome on Debian 12. **Note:** I actually ended up setting the favorites system-wide for all users via 00-favorite-apps - but the same is observed either way). Image

Symbolic link to application - working directory

Lets say i have a bash script in a folder called
, which reads data from files in a subfolder named
.
The paths in the script to the files are all relative to this "Programming" folder.
"test" > ./data/test.txt
.
So the working directory should always be the "Programming" folder.
When the script passes all tests, it is finished and i thought i could easily copy the whole content of the "Programming" folder to a subfolder in
/opt
, lets say
/opt/myapplication
and then make a symbolic link in the
/usr/bin
folder called
, which links to the script in
/opt/myapplication/bash_script
to make it reachable in the environment. But the problem is, if i now call myapplication from anywhere the working directory is
$PWD= #actual shell directory at script start
$0=/usr/bin/myapplication
${BASH_SOURCE}=/usr/bin/myapplication
and my application fails. I thought the symbolic link will change the working directory, to where the file is located. What is the common practice in Unix to set the working directory always, to where the executed file is located, to use relative paths ??

After going through their website and reading numerous articles about it, I don't see the details of a prominent marketing point documented anywhere, namely *a list of which applications are bundled with the Zorin OS 17 Pro distro.* For example, here is a page on Zorin's website stating that their Pro version is "bundled with alternatives to over $5,000 of professional software": https://zorin.com/os/pro/#productivity But the bundled apps are not specified. So, which applications *are* bundled with the Zorin OS 17 Pro distro?

My organization will require Multi-Factor Authentication (MFA) in a few days and we use Microsoft accounts. On the internet I read there are authenticator apps for Linux. One of them is Authenticator . I'm not up to date with Microsoft services, however, it looks like the app offers many, i.e. "Microsoft To-Do" and "Microsoft Azure". Also on Microsoft's website there are several different methods: "Authenticator app", "Phone", "Alternate phone", "Security key", "Office phone". I tried to set up the "Authenticator app" and "Security key" authentication methods. In both cases I ended up with the following error:
(authenticator:365334): Gtk-CRITICAL **: 08:26:43.787: _gtk_css_corner_value_get_y: assertion 'corner->class == >K_CSS_VALUE_CORNER' failed
2023-07-12T06:26:49.446034Z ERROR authenticator::widgets::accounts::add::imp: Failed to load from QR Code file: Invalid OTP uri format, expected otpauth, got phonefactor
As I understend this error message: QR code I got can only be used with smartphone app and Authenticator GNOME app is not meant to replace Microsoft's Android Authenticator app but some other Microsoft MFA service? I don't have Android nor IOS smartphone, I don't use Windows either. Is it possible to use this MFA service with Linux?

Trying to axe extra connections - ex: visualstudiocode wants to send some junk, and instead of going through the clunky settings there, I just wanna strip it of internet access except when I may want to. Any recommendations? I believe ages ago I saw someone show a command to container-ize just an executable for subset resources? Seems like if the symlinks or permissions were right it would be doable on linux? Thanks! Edit: Ideally I can just run a terminal command to disable/enable access to the internet when opening the application - or have two icons.. Edit 2: Reason for this, is I want to use the internet, but not have my editors or other non-essential applications taking up resources.

For reference, >A **.ipa** file is an iOS and iPadOS application archive file which stores an iOS/iPadOS app.     — Wikipedia
