Linux

yt-dlp

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

off the top of my head:

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

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 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.

I am thoroughly enjoying using mcfly.

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

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

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.

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.

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.

I mentioned this in another post, but tmux is awesome

i use kibi as a text editor

i also have terminal client called alacritty

also doas instead of sudo

• 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

I have mostly replaced all command line stuff with Emacs, but there are still a few CLI utilities that I continue to use, whether I am in the CLI directly or whether I am using Emacs:

• tmux or screen (terminal multiplexing)
• bash (shell scripting)
• grep, sed (filtering, formatting)
• ps, pgrep, pkill (process control)
• ls, find, du (filesystem search)
• ssh, nc, rsync, sshfs, sftp (remote access, file transfer)
• tee, dd (pipe control)
• less, emacs, diff, patch, pandoc (text editing)
• man, apropos (manual)
• tar, gzip, bzip2, xz (archiving)
• hexdump, base64, basenc, sha256sum (data encoding, checksums)
• wget, curl, (HTTP client)
• dpkg, apt-get, guix (package management)
• mpv (media player)
• ldd, objdump, readelf (inspecting binary files)
• zfs (maintaining my backup filesystem)

fd - alternative to find, very useful. Icat or chafa for images via sixel or kitty. Ranger file manager Exa for ls replacement Bat for cat replacement Fzf Patched mpv for kitty terminal with video support. Btop for nicer top Swayimg or ueberzueg for image overlay Scrcpy, adb and waydroid for Android software Ripgrep Wl-clipboard, wlr-randr and cliphist Wofi or rofi Gammastep

ffmpeg

alsamixer
