Linux

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 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

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 use fuck to fix typos

grep goes crazy if you know your regex

jq - super powerful json parser. Useful by hand and in scripts

The pipe (|), which if you think about it is the basis for function composition.

jq?

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.

Control+r == search through your bash history.

I used linux for ten years before finding out about that one.

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.

awk

I find myself using tldr a lot since finding out about it. It's just so useful for commands that I don't use enough to commit to memory.

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

bc

It's a simple command line calculator! I use it all the time.

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.

Using rust rewrite of coreutils you can cp -g to see progress. Set an alias :)

+1 for Caddy, completely replaced nginx. also...

• Starship - shell prompt
• tmux - terminal multiplexer
• parallel - parallel command runner
• restic - backup tool
• age - modern file encryption

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.

CTRL-L to clear your terminal output. Or type clear

tmux - makes managing remote SSH sessions a breeze.

tomb - A little FOSS encryption utility that runs in the CLI. Easy, cute, effective. Tomb Utility

Man

sshfs

pipeviewer or pv

dd is probably well known, but one of the simplest and most powerful ways to accidentally delete all data on your hard drive. dd if=/dev/random of=/dev/sda

Discovered about rg recently and it is cool!

I love ncdu for seeing where all my storage is being taken up.

ddccontrol... it looks complicated on the surface but it's really not and being able to control monitor brightness without fcking around in some garbage monitor OSD is a god sent and should be the standard

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 line

socat - connect anything to anything

for example

socat - tcp-connect:remote-server:12345

socat tcp-listen:12345 -

socat tcp-listen:12345 tcp-connect:remote-server:12345

I think socat is a really powerful und underrated tool
