If a Debian bug number is referenced in the changelog of an uploaded package, it is automatically closed with a generic message: We believe that the bug you reported is fixed in the latest versi...
I noticed in winetricks that it can install windows dlls to the wine folder. It even gives an option to install almost all of them at once. When should someone install these instead of staying with...
I'm posting the same answer on both sites, because the questions are basically the same. Personally, I am in favor of merging Linux Systems Codidact and Power Users Codidact, ideally by transferri...
I have an old Mac Mini (Late 2009 model) kicking around, and as Apple stopped providing patches for it (and as I'm not going to put an unpatched system on the Internet), I was looking for a Linux d...
From man ssh_config: This file is used by the SSH client. Because of the potential for abuse, this file must have strict permissions: read/write for the user, and not writable by others.
How do I make my computer request a new IP from DHCP? I am using Arch with NetworkManager.
By digging further into the details of xdg-open, I stumbled upon this page in the Arch wiki. There it states that xdg-open will delegate the task of opening a file to the handler of the Desktop En...
After a force shutdown on Ubuntu 22.04, installed on a Lenovo Legion 5, the OS seems to have lost its ability to recognize the built-in touchpad or to connect to the internet. For the backstory......
There are a couple of ways of handling this (on PC's in general. I do use Linux, but not Arch, and this will work). The first way is to statically assign an IP address. While you SHOULD be able...
I am using Linux Mint 20.3, with Cinnamon as a window manager. I have a folder named .pytest_cache on my Desktop: $ ls -1A | grep '^\.' .pytest_cache I know that if I open a Nemo window, navi...
I tried to think of some for a while, but couldn't find any good ones. That said, there's plenty of programs I don't know. For reference: $ echo -en "hello\nworld" | tee 1.txt | bat -A ───────┬──...
My thoughts on the matter are clear from the question, but I'll add some example topics that could be covered by this "basics compendium": A "curriculum" of sorts that lists all the basic topics...
Authentication events such as logging in are ultimately handled by PAM, the Linux Pluggable Authentication Modules project. PAM is very flexible and different Linux distributions will ship with dif...
When I enter the login password incorrectly 3 times, my computer locks me out from attempting a login for 10 minutes. How can I increase the number of attempts?
As the keyboard layout wiki suggests, loadkeys only sets the keyboard layout for the current session. In order to persist these changes, the KEYMAP variable must be set in /etc/vconsole.conf. Thi...
I'd forget about messing around with console commands and X configuration files, and just change the keyboard layout in the GNOME Settings panel: You can access this by hitting the Windows key a...
****Since upgrading to Ubuntu 22.04 recently, immediately after a reboot I have WiFi to an internet hotspot as I did prior to upgrading. After suspend then resume, the network is no longer working...
A solution I often use (and which is ultimately a variation of the find-based approach in the answer by Canina) also uses find, but only prints a single . per file: find . -maxdepth 1 -type f -pri...
I do this occasionally. It is sometimes useful to compare file titles where they aren't fixed lengths. For example: 01 02 The Beatles The Rolling Stones Help Satisfaction .m...
You can use -Suw for that. I haven't actually tested it, but it should work according to the documentation. From man pacman (redactied/edited for clarity): UPGRADE OPTIONS (APPLY TO -S AND -U) ...
Question How do you specify underscores as Vim word boundaries when using vim mode in either bash or zsh? MWE w on this_word should place the cursor on the underscore. A second w should place th...
I run Windows games with Wine, and use bwrap to sandbox them. I've noticed that passing --unshare-net to disable the network breaks many, many games (they fail to start with no obvious error messag...
I use Wine to play Windows games. As is well known: Wine is not a sandbox Windows games are proprietary blobs and can contain malware Windows malware can potentially harm Linux through Wine ...
