Linux

Ncdu is a really useful little utility that shows you what directories are using the most space on whichever drive/directory you select. Really useful little piece of software.

hdparm is another neato one that let's you test the read speeds of your drives, though it's more so something ya use once and forget exists.

Also, though Neovim is more popular, Helix deserves some recognition. It's a rust based, vim inspired text editor which removes the need to configure it, making it easier for people trying to get into terminal text editors.

Edit: Jerboa removed the first name, my bad.

xclip is incredibly useful to get and set data from the clipboard!

gopup is to html what jq is to JSON. It allows you to parse html to extract specific data for a given selector.

I mentioned this in another post, but tmux is awesome

fzf for quickly matching file names especially deep in the directory hierarchy

ripgrep for quickly searching for text content within files

dtrx for handling the right extractions of different archive types

I basically live in nvim. Being able to configure my editor in an actual programming language makes it so much more useful to me than vim could ever be.

Ranger and/or vifm as file managers. Can't live without them

EDIT: lemmy changed where this comment went. (BUG)

• gcalcli : helps accessing google calendar using calendar api
• neix : rss reader
• I don't know if it counts but : fish shell

They might have specific uses that most users might not need and there may be better alternatives but some of the ones I've been using are:

CISO - A command line tool for making compressed ISO files that can be used in emulators and some video game consoles running custom firmware.

RAR - The Linux version of WinRAR, which doesn't have a UI like the Windows version does.

Flatpak - Probably well known but in case a newer Linux user sees this, it's used to download and install flatpaks from Flathub.

ffmpeg

alsamixer

And on a more devops front k9s https://k9scli.io/

argos-translate for offline machine language translation.

tmux & neovim for editing files and organizing the terminal displays.

asciinema for recording and playing back terminal sessions.

I am thoroughly enjoying using mcfly.

i use kibi as a text editor

not a cli tool, but i also have a terminal client called alacritty

also doas instead of sudo

off the top of my head:

• vim
• git
• bash
• make
• whatever-compiler-im-using
• curl
• less
• grep

Kakoune (kak) has become my go to vim replacement. Keybinds are tweaked slightly to be more user friendly and more transparent about what it is you're doing.

I never mastered vim binding as well as I liked, but the more intuitive and better communicated binds for kak were easy to learn in comparison and I quickly swapped over.

I personally like bat, fd, rsync, btm, btop, rg, and nix. Nix is a package manager tho, so that's a whole bag of worms.

bat is a nice one

• ranger and mc - both are file managers, and their approach is so different that I choose one of them I need at the moment depending on what do I want to do (mc for traditional file management, ranger for looking around the directory tree and peeking into files)
• htop, tmux - classics
• weechat, profanity - for my IM needs
• ripgrep - for searching through files
• magic-wormhole for file and ssh public key exchange
• mosh for when the network conditions aren't ideal
• nmap to see if that machine I've connected into the network is up and what IP did it get
• bat for quick looking into files
• gdb, with mandatory gdb dashboard
• nvim for serious text and code editing, micro for more casual editing
