Guix is a rolling release distro. Another well known rolling release distro is Arch Linux. In Arch, you are expected to frequently do system updates. Partial updates are not supported. In my exper...
I don't use Gnome, but I'm guessing it relies on xdg-open to figure out what program to use. Your first step would be to do xdg-open ~ to see if it uses the same incorrect program. If so, great - ...
It's NetworkManager that sets the IPv6 link-local address and per default it doesn't use the conversion from MAC to IPv6 address of that converter, called modified EUI-64. As mentioned in the linke...
There's multiple, sometimes overlapping ways of altering the DPI globally on Linux. You should first ensure these are properly configured and Spotify is still not using them correctly. However, Sp...

By using the non-interactive --quick-add-key method. This adds separate signing and encryption subkeys with expiration date one year from now: $ gpg --quick-add-key YOUR-PRIMARY-KEY-ID ed25519 sig...
If I understand you correctly, you want to skip empty lines at the beginning of a file/stream strip leading and trailing whitespace of non-empty lines skip empty lines at the end of a file/str...
systemctl is a tool for controlling systemd, the "new" Linux init system (actually it's been widely used for 10 years now). Systemd is the first process that runs at boot, which then brings up all ...
I have an Arch Linux machine connected to a LAN by ethernet. The router runs OpenWRT. DHCP assigns IPs to this machine like 192.168.1.* - quite typical. I want the IP to always be 192.168.1.10. I...
I can start services with systemctl start. I can see logs with systemctl status or journalctl. But by the time I run the second the process has already started. I'd like to start a service and imme...
I'm going to write some systemd services. All of these can only be run if a certain website is up. I thought I could create a ~/.config/systemd/user/website.service this: [Unit] Description=Confi...
How can I search for files on my system? Ideally, I would like to search by various criteria, like date, name, extension, etc.
The systemd manual gives a list of path where systemd looks for unit files. However, I want to isolate my units in a path of my own choosing. Is it possible to configure systemd to add some path t...
~/.config/systemd/user intended purely for units created and managed by the user manually, or are there any automated processes that expect to control it? For example, do packages or programs ever...
Grove's answer is likewise good, but OpenSSH introduced ProxyJump (-J) in 2016 with v7.3, making it even easier to chain SSH hosts together: ssh -J user@interstitial.example me@destination.example...
Historically, cron was the main way to schedule tasks on Linux. Briefly, there will be some file like /etc/crontab which will contain one line for each task. The line starts with a schedule string ...
A first quick solution I hacked up was to sync via NAS. Synology NAS served as a synchro point. I synced via git repo. etckeeper was used to sync machine config, pass was used to sync passwords. S...
The standard way to schedule tasks in most Linux systems nowadays is to use systemd timers. This requires writing a systemd timer config file, which has syntax similar to INI. This is summarized i...
In i3, is there a way to move an entire workspace to another monitor, including all windows it contains?
When hardening my system with Lynis I had information about /etc/issue and /etc/issue.net being found weak. Lynis redirects me to Enterprise, which is a paid product and a bit overkill for my home...
I have multiple screens and I often connect and disconnect monitors while the system is running. i3 assigns a workspace to each monitor, but does so unpredictably. Sometimes my main monitor is work...
It turns out, that Lynis test code lives in /usr/share/lynis/include/test_banners which gave me a way to find what banner is considered good. :-) In my case, it's to have 5 or more specific keyword...
Let's say I have workspaces 1, 2, 3 on screen A and 4, 5 on screen B. Currently workspaces 1 and 4 are active. With my current config, moving a window to another workspace never activates it. How...
