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 love
ncdu
for seeing where all my storage is being taken up.pdfgrep for the well maintained company’s project folder of your choice.
This looks very cool!
socat
- connect anything to anythingfor example
socat - tcp-connect:remote-server:12345
socat tcp-listen:12345 -
socat tcp-listen:12345 tcp-connect:remote-server:12345
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
It also supports ripping playlists. Fantastic to archive a set locally…
Since everyone keeps mentioning yt-dlp I gotta ask: what’s wrong with the original youtube-dl? I keep using it, it works, it’s still being updated.
yt-dlp has sponsorblock features, youtube-dl does not.
A few that I use every day:
- Fish shell
- Starship.rs
- Broot (a brilliant filesystem navigator)
- Helix editor (My favorite editor / IDE, truly the successor to vim IMO)
- Topgrade (updates everything)
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
Nice!
Helix is great thanks
Do you have experience with either ranger, lf, or yazi? I’m wondering how broot compares. Big fan of file ranger, and this looks very similar.
I’ve used ranger, but I’m not as big a fan of it as broot.
Could you explain them in more depth? I opened them and don’t know
Fish is a replacement of bash that’s a bit more user friendly (has some cool auto completion features out of the box and more sane behaviour like handling of spaces when expanding variables). I personally started to use nutshell recently but unlike fish it’s very different from bash.
Starship is a “prompt” for various shells (that bit of text in terminal before you enter the command that shows current user and directory in bash). I haven’t used it but AFAIK it has many features like showing current time, integration with git, etc.
Yep, here’s my Starship prompt, for example:
So, I have it configured to show:
- the exit code of the last command (if it’s non-zero),
- the duration of the last command (if it’s longer than 2 seconds),
- the time (when the last command ended),
- the current directory,
- the current Git branch, and it also shows some Git status information, for example the
means I have something stashed,
- and finally the technology in use in a repository/directory, so in this case that repo uses Rust and the compiler version is 1.83.
Thanks for adding this. What does stashed mean
Oh, when you’re coding something in a Git repo and you realize that you need to make a different change before you continue coding (e.g. switch to a branch, pull newest changes, or just create a separate smaller commit for part of your change), then you can run
git stash push
to put away your current changes, then make your other change, and then rungit stash pop
to bring your ongoing changes back. I recommend readinggit stash --help
, if you want to use it.Sometimes, though, you might end up just taking it into a different direction altogether or simply forget that you had something stashed. That’s when that indicator comes in handy. Because while you can have multiple things stashed, I do find it’s best not to keep them around for too long. If you do want to keep them for longer, then you can always create a branch and commit it as WIP onto there, so that you can push it onto a remote repo.
grep goes crazy if you know your regex
I love flexibility with regex, personally I use ugrep as it also allows utilization of boolean and/or/not logic for more complicated searches.
I can never get grep to work consistently on Mac and Linux. Now, ripgrep OTOH…
That’s because Macs generally use BSD-based command line tools instead of GNU ones. You have to do a lot of Homebrew jiggery-pokery to approximate a GNU environment. Know Your Tools: Linux (GNU) vs. Mac (BSD) Command Line Utilities
Alas, doesn’t fit my purpose since it requires action by the script user. I usually just use perl in those situations
I was expecting this one.
Most listed in some form elsewhere, but
- Ugrep
- ranger/lf
- tmux (splitting terminal and detatching/reattaching when I’m sshing onto server, etc)
I’ve also been enjoying Kate. It’s a decent text editor, but the ability to Ctrl + / to pipe selected lines through any Linux command (Uniq, shuf, etc) is a bit of a superpower for an editor
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.tmux is my religion
I’m not sure how underrated it is but the exec feature in
find
is so useful, there are so many bulk tasks that would just be incredibly difficult otherwise but instead are just one lineI really enjoy erdtree as a ls replacement
Using rust rewrite of coreutils you can
cp -g
to see progress. Set an alias :)Where can this variant of coreutils be found? This is the first time I have heard of it.
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.
Also, you can make
yes
return anything:yes no
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 typecd /super/long/directory/path
, you can typezoxide 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 systemYou 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
xargs
Very true. I used to do magic with xargs when working as a sysadm. Also a good way to mess up on a grand scale. Ask me how I know.
So, how do you know?
By not testing it properly before running it over the whole file system resulting in a few hours of extra work cleaning up the mess I made.

(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.
