From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I maybe need to correct my post. I am talking about system utilities like Device Manager or something else.
Why would I want gui for those things? CLI is often a better interface. Being able to grep lsusb rather than scanning a gui for an entry is much better. It's easier to pipe to an email as well. Screenshots don't allow copy/paste...
As a newcomer to CLIs, GUI are great because you don't need to know what you're looking for. I can just open the devices window, and they're all there, with most of the extra hardware stuff that's not actually a real device already cleaned out.
To do the same with a CLI would take me 10 minutes of looking up what the hardware commands are, 5 minutes figuring out flags, and 30 minutes researching entries to see if they're important. Even just a collapsible list would make that last step so much easier. And no, I can't grep for what I need, because I don't know what I need, I just know something in there is important with a vague idea of what it might look like.
Once I figure that all out for one thing, the best I can do is write that to a notes file so I don't need to search so far next time, but there's a good chance that I'll need a different combination of commands next time anyway.
Not hating on CLIs, just wishing I could figure out how to use them faster.
apropos - command to list relevant commands tldr [command] - shows the most commonly used flags/options for that program
apropos comes installed by default (on debian at least), tldr needs to be installed with your package manager
As someone who cannot even remember tar flags (inser xkcd here), tldr is very helpful
Your 45 mins becomes 5 mins now. Hope that helps
👆 exhibit A of why Linux can be difficult for newcomers
Linux has been very successful without catering to those who don't want to learn new things.
Hmm, what does lsusb do?
The name is constructed from two parts:
ls: listusb: usbIt lists usb devices that your machine (/kernel) knows has been connected; they may not necessarily be usable.
E.g. I have some sound output device connected via USB to one machine. On most of my machines I've switched from pulseaudio to pipewire¹, and I figured I'd bring that machine closer to the others so there's less variance. Unfortunately the sound output device didn't want to work with pipewire. The problem manifested as no sound and pipewire not listing the device.
lsusbhelped me know that the machine at the very least recognized the device, but wasn't currently able to use it. (It did actually also show up as an error indmesg -H, but reinstating pulseaudio let the device work again as normally. So now I just have to live with a situation where some machines use pipewire because ~bluetooth~ and others use pulseaudio because … usb?¹)¹ There's a memory of ALSA vs OSS I didn't want to be reminded of
Ah thanks, I wonder if GUI tools for this is useful. Especially if it is for system diagnostics.
Lshw, lsusb, etc and grep do that
