Linux

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.

Which Linux command or utility is simple, powerful, and surprisingly unknown to many people or used less often?

This could be a command or a piece of software or an application.

For example I'm surprised to find that many people are unaware of Caddy, a very simple web server that can make setting up a reverse proxy incredibly easy.

Another example is fzf. Many people overlook this, a fast command-line fuzzy finder. It’s versatile for searching files, directories, or even shell history with minimal effort.

I like https://github.com/aristocratos/btop personally. It's way prettier than the normal top command which you use to watch processes to find the one that's hogging all of the CPU or whatever. And it's not so much that it's underrated so much as it's not very well known or distributed by default.

awk

..for parsing the output of other commands quickly and simply. Then that parsed output can be used to create simple log messages or be passed as args to other scripts. Powerful.

Do you have to wear the fedora to run this command?

Idk a lot of commands but I think wget for downloading webpages and rsync for syncing devices are pretty awesome

The first time I used wget I felt so awesome. I was grabbing some extra music files I think it was for Ur-Quan Masters.

Bat, a cat alternative.

Lsd, an ls alternative.

Procs, a ps alternative.

Renane, because it's great.

People always sleep on script. It's badass and let's you do goofy things like this while keeping standard terminal formatting: https://github.com/StaticRocket/dotfiles/blob/043e9a56cc9515060188ec4642e4048c0dd6c000/dot_bashrc#L79-L94

Inshellisense is teaching me a lot. :) It's an autocompleter.

+1 to caddy. There are some services that set safe headers following the recommendations outlined by Mozilla but others don't control headers as strictly. Caddy is the only web server that I found that supports loose default header values. These values will be selected unless the upstream application specifies their own values.

You can do something similar in nginx but it requires playing with maps and has a little more indirection than I'd like.

Just wish caddy was capable of starting as root and stepping down permissions like Nginx. I have certs being managed by other tools and have to make sure they are installed and chowned for caddy's use when they are cycled.

I just started the process of switching from nginx Proxy Manager to Caddy yesterday, and even before setting up a single rule, I'm enjoying it more than NPM. Really wish I would have heard about it sooner!

I loved glances until I switched to btop with Hot Purple Traffic Light theme, and I doubt I'll switch again. Check it out!

ia: internetarchive https://archive.org/developers/internetarchive/cli.html cli tool, i only use it for downloads, it can a bit more than the eye meets first, like accepting a wildcard to download certain files or specify other stuff. I have an incomplete script to help me with that, which I want to share in the future. The only problem is, that the internetarchive at archive.org is often very slow at downloading.

I abused debfoster for years... it kept my machines running very, very clean.
