![]() But a few basics suffice to get you started.Īny computer on a network has an IP address. This article can’t teach you everything about computer networks. This article shows you how to change its settings using firewall-cmd. It’s part of the network functions in the Linux kernel inside. For instance, if you’re running a laptop at school or in a coffee shop, you probably don’t want strangers poking around on it.Įvery Fedora system has a firewall built in. They are most frequently used to prevent outsiders from contacting or using network services on a system. Now gitg works again, as it used to.A network firewall is more or less what it sounds like: a protective barrier that prevents unwanted network transmissions. If (like me), you are still not satisfied with this, you can add a shell alias to get the traditional command name back: PATH=$PATH:$HOME/.local/share/flatpak/bin ![]() After adding that directory to your PATH, you can run gitg like this: It now installs shell wrappers for the flatpak run command in ~/.local/share/flatpak/bin. Thankfully, flatpak has recently gained a way to recover the familiar interface. This is certainly a departure from the traditional commandline, and could be considered cumbersome (even though it has bash completion for the application ID). Unsurprisingly, the command to do so is called run, and it expects you to specify the unique application ID: flatpak run Probably the most important thing you will want to do with flatpak is to run applications. To just check if updates are available, you can use flatpak remote-ls -updates Launching applications Which will install available updates for all applications. The most straightforward way to so is to just run flatpak update If you choose to install system-wide, you will get a polkit prompt, since this is a privileged operation.Īfter installing applications, you should keep them up-to-date by installing updates. You can choose the location with the –user and –system options. An important detail to point out here is that applications can be installed in system-wide (in /var) or per-user (in ~/.local/share). Will do that for you, and flatpak install If you want to find applications, then flatpak search It is quite common to have more than one source for flatpaks enabled. flatpak has many commands that are worth exploring, I’ll only mention the most important ones here. ![]() Where rpm-ostree controls your OS image, flatpak rules the applications. Alternatively, you can use the –reboot option to tell rpm-ostree to reboot when the upgrade command completes. Should be in your repertoire of commands as well. ![]() You have to reboot into the new image to see the changes, so systemctl reboot Recently, rpm-ostreed has also gained the ability to check for and deploy upgrades automatically.Īn important thing to keep in mind is that rpm-ostree never changes your running system. You can run this command as normal user in a terminal, and rpm-ostreed will present you with a polkit dialog to do its privileged operations. To get the latest update for your OS image (the terminology clash here is a bit unfortunate rpm-ostree calls an upgrade what most Linux distros and packaging tools call an update). To get some information about your OS image (and the other images that may be present on your system). ![]() rpm-ostreeįirst of all, there’s rpm-ostree, which is the commandline frontend to the rpm-ostreed daemon that manages the OS image(s) on the Atomic Workstation. on But there are a few commands that are essential to life on the Atomic Workstation: rpm-ostree and flatpak. I am not going to talk about these, since I don’t know them very well, and they are covered, e.g. So, what about the commandline in an Atomic Workstation environment? There are many container tools, like buildah, atomic, oc, podman, and so on. But I am not really the easiest target audience for an IDE like GNOME Builder, having spent most of my life on the commandline with tools like vim and make. In my recent posts, I’ve mostly focused on finding my way around with GNOME Builder and using it to do development in Flatpak sandboxes. Note: Fedora Atomic Workstation has recently been renamed to Team Silverblue. ![]()
