It should be hardly surprising at all for longtime Linux users aware of how Fedora Linux tends to always ship with the most modern open-source compiler toolchain support possible, but for Fedora 37 this autumn they again are planning for the latest and greatest...

Being worked on the past several years by Google engineers and others has been the KernelMemorySanitizer (KMSAN) that has already found more than 300 kernel bugs even prior to being mainlined.

Need A Linux Kernel Module? Scratch That  Hackaday

Manage your files in your Linux terminal with ranger Sumantro Mukherjee Mon, 07/04/2022 - 03:00 Register or Login to like Register or Login to like

The most basic way to look at your files and folders is to use the commands ls and ll. But sometimes, I want to see not just the file metadata but also the contents of a file at a glance. For that, I use ranger.

If you love working out of your console and using Vim or Vi, and you don’t want to leave your terminal for any reason, ranger is your new best friend. Ranger is a minimal file manager that allows you not only to navigate through the files but also to preview them. Ranger comes bundled with rifle, a file executor that can efficiently choose programs that work with a given file type.

Installing ranger on Linux

Ranger can be installed in Fedora or any RPM-based distro by running

$ sudo dnf install ranger

Ranger is also available for other distros and macOS.

Using ranger for the first time

As a user, you can start ranger by simply typing $ ranger on your favorite terminal. The arrow keys give way to the navigation. This screenshot is an excellent example of how I can preview the code of the config.example file stored in Kernel-tests.

Picking any file and hitting F4 opens up your default editor and lets you edit the files right away!

What about images and videos?

Using rifle with ranger lets you quickly find the program associated with a given file. Hovering over an image and then trying to open it is very simple; just hit Enter. Here’s how that looks:

Hitting i on an image file will give the user all the EXIF data. Hitting Shift+Enter will open the PDF file.

The same key combo will open and start playing videos in the system's default video player that supports the codec. The example below is an mp4 video, which plays just fine on VLC.

The following key bindings work well unless otherwise configured by the Vim user.

j: Move down
k: Move up
h: Move to parent directory
gg: Go to the top of the list
i: Preview file
r: Open file
zh: View hidden files
cw: Rename current file
yy: Yank (copy) file
dd: Cut file
pp: Paste file
u: Undo
z: Change settings
dD: Delete file

Console commands

Sometimes I have a folder that contains screenshots of a particular software when I am drafting articles. Selecting or marking files by hitting Space and then typing :bulkrename helps me move all the weird timestamps to, for example, lorax1, lorax2 , and so on. An example is below:

Other useful console commands include:

:openwith: Open a select file with a program of your choice
:touch FILENAME: Create a file
:mkdir FILENAME: Create a directory
:shell : Run a command in shell
:delete: Delete files

Will it work in tty2/3/4?

As someone who works in quality assurance (QA), I've found that searching for logs and reading them has never been easier. Even when my Gnome Display Manager crashes, I can switch over to my tty2, log in with my username and password, and start ranger with superuser permission, and then I am all sorted to explore!

Ranger is a great tool for working with files without ever having to leave the terminal. Ranger is minimal and customizable, so give it go!

Try this lightweight open source tool to preview files without leaving the terminal.
