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 think a lot of people don't realise that yt-dlp works for many sites, not just YouTube

I used it recently for watching a video from tiktok without having to use their god awful web UI and it was amazing

[-] GenderNeutralBro@lemmy.sdf.org 31 points 2 years ago

Also works on Twitch with the added benefit of NOT playing ads (you still get breaks, just with a placeholder screen instead of the commercial).

mpv has yt-dlp support built in, so it can just play the streams directly.

I heard about helix from you and I've used it for a year and a half or so now, it's by far the best editor I've used so far and I can definitely vouch for it

I'm a big fan of screen because it will let me run long-running processes without having to stay connected via SSH, and will log all the output.

I do a lot of work on customers' servers and having a full record of everything that happened is incredibly valuable for CYA purposes.

[-] Static_Rocket@lemmy.world 16 points 2 years ago

I'd recommend tmux for that particular use. Screen has a lot of extras that are interesting but don't really follow the GNU mentality of "do one thing and do it well."

nano was and still is vital to me learning and using linux, I will not learn how to use vim so if the distro forces it to be default im not using it.

Why is editing text so convoluted for seemingly no reason.. also hate that vim must be used for certain files.

I know tmux is incredibly popular, but a good use case for it that isn’t common is teaching people how to do things in the terminal. You can both be attached to the same tmux session, and both type into the same shell.

zoxide. It's a fabulous cd replacement. It builds a database as you navigate your filesystem. Once you've navigated to a directory, instead of having to type cd /super/long/directory/path, you can type zoxide path and it'll take you right to /super/long/directory/path.

I have it aliased to zd. I love it and install it on every system

You can do things like using a partial directory name and it'll jump you to the closest match in the database. So zoxide pa would take you to /super/long/directory/path.

And you can do partial paths. Say you've got two directories named data in your filesystem.

One at /super/long/directory/path1/data

And the other at /super/long/directory/path2/data

You can do zoxide path2 data and you'll go to /super/long/directory/path2/data

Not powerful, but often useful, column -t aligns columns in all lines. EG

$ echo {a,bb,ccc}{5,10,9999,888} | xargs -n3
a5 a10 a9999
a888 bb5 bb10
bb9999 bb888 ccc5
ccc10 ccc9999 ccc888
$ echo {a,bb,ccc}{5,10,9999,888} | xargs -n3 | column -t
a5      a10      a9999
a888    bb5      bb10
bb9999  bb888    ccc5
ccc10   ccc9999  ccc888

yes

The most positive command you'll ever use.

Run it normally and it just spams 'y' from the keyboard. But when one of the commands above is piped to it, then it will respond with 'y'. Not every command has a true -y to automate acceptance of prompts and that's what this is for.

I don't see anyone mentions htop. So, I will:) Just works, could be installed in any distro. Much more friendly than top but isn't bloated with features as some other alternatives are.

yq is crazy cool for converting between different text-based data formats such as yaml, json, xml, csv and others, and it has a super nice pretty-printing function as well. I use it all the time!

Just be aware that your distroy might come with a yq variant too, but possibly one that isn't as powerful as the one I linked. I know this to be true at least for Ubuntu.

vd (VisiData) is a wonderful TUI spreadsheet program. It can read lots of formats, like csv, sqlite, and even nested formats like json. It supports Python expressions and replayable commands.

I find it most useful for large CSV files from various sources. Logs and reports from a lot of the tools I use can easily be tens of thousands of rows, and it can take many minutes just to open them in GUI apps like Excel or LibreOffice.

I frequently need to re-export fresh data, so I find myself needing to re-process and re-arrange it every time, which visidata makes easy (well, easier) with its replayable command files. So e.g. I can write a script to open a raw csv, add a formula column, resize all columns to fit their content, set the column types as appropriate, and sort it the way I need it. So I can do direct from exporting the data to reading it with no preprocessing in between.

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.
