!commandline@programming.dev is basically this for terminal programs.
Those are the ones that came to my mind
May I request for the people that answer, don't just answer with the name of the program, tell us what it does, why you like it, bonus points if you post a link to where to get it as well.
I'm a relatively new Linux user and I've been going through threads that ask the same sort of question and 90% of the answers are just "[app name]" and nothing else. I know I could just search it for myself, but be kind and write a few words extra.
Some applications I've not seen yet:
https://ntorga.com/gzip-bzip2-xz-zstd-7z-brotli-or-lz4/
lz4 - fastest compression/decompression (several GB/s); compression is good, but not amazing; very little CPU usagezstd - very fast compression, fast decompression (few GB/s compression; ~600MB/s for decompression; better or equal compression compared to zip, depending on level)cloc <folder> - gets lines of code for a project/foldergdu <optional location> - like ncdu, but faster (written in go) - think TreeSize/WinDirStat for the terminalstat <file> - built-in application to show the modified, created, etc stats for a file.hyperfine - benchmark for binaries - run this in front of a command to have it run multiple times, and show some statistics.jpegli - great to recompress JPEG files into smaller filesizes, with only very few/minor visual effects.just - used with a Justfile in a project so I can run just to see the commands, or run just test, just clean, just ... to run project-specific commands.msedit - ye olde edit.com, reborn! Feels a little bit cursed to use an MS text editor on the terminal, but it's better for beginners than nano or micro or whatever.oxipng - lossless png compressionpngquant - lossy png compression (it forces the file to use a palette of n colors, which reduces the colors used, so it will affect your files, unlike oxipng.upx - compress binary filesvisidata - analyses csv files, and shows some stats. Like Data Wrangler for the terminaloxfmt - think "oxidized prettier" (file formatter for programmers)Whatpulse - I've been tracking my keypresses since 2005. not a terminal application, unlike the rest.fsearch - Linux alternative to Everything by Voidtools. It will be a little bit different, but it does the job. mlocate package, with the sudo updatedb and locate commands, if you prefer the terminalkeepassxc - password managerspeedcrunch - best GUI calculator, IMO. Just a bar for input, and a bunch of stored results above it. Use the ans variable to use the previous answer in the current calculation, like ans*2 to multiply the previous answer. Or use variables, like x=5, y=2, x+y: 7.For audio work, I use 4 programs: LMMS, yt-dlp, demucs, and audacity
My workflow usually goes yt-dlp to download audio/samples, then either audacity and demucs. Audacity I use for splicing the clips I need, and if its necessary, I use demucs to split stems either on the full song before splicing clips with audacity or splitting stems after getting the clips I want. I then use LMMS to sample and layer drums and other samples usually.
fish - Ever since I've made the switch to Linux, the terminal has been part of the experience. And, honestly, I wouldn't want it any other way. Besides its efficiency, I also very much enjoy how it automatically keeps track of everything I do within. I don't get that functionality whenever I do something within a GUI. But bash left a lot to be desired in that regard; its history simply didn't record everything. It was also pretty bare-bones; no syntax highlighting, no auto suggestions etc. Thus, after trying to bend bash (and later zsh) to my will and ultimately being dissatisfied with the janky mess I was left with, I finally gave in to at least give fish a honest try. The rest is history. Heck, it's the very first thing I install on a machine.
yeah Fish along with DOOM Emacs are the first two things I install on my machine.
I used to use zsh with oh my zsh and various plugins and it would totally slow down my nixos system so then I decided to give fish a try and surprise surprise it had all the stuff I had to add on to zsh already baked in.
easily the best shell out there.
I saw fish recommended for new users in openSUSE's documentation. I want to try that. There is a way to switch to Bash for a particular script, right? I know that file-based scripts have the shebang line, so that's a non-issue, but what if I have a Bash command I copied from the Internet and my default shell is fish?
As I suppose the other user already went over your main query, I'll instead focus on what might have felt rather innocuous.
my default shell is fish
I subscribe to the school of thought that one should not change their default shell^[I suppose it could be fine~ish as long as it's POSIX compliant AND compatible with bash. Which, unfortunately, fish happens to be neither of the two.] through invoking chsh (or whatever other method that applies changes to /etc/passwd). This article does an excellent job at laying down the reasoning (and the recommended alternative). FWIW, the alternative's day-to-day experience provides all of the pros without any of the cons.
Just prepend the command with "bash". If the script changes environment variables and you need that to happen in your fish environment there is https://github.com/edc/bass
cd with superpowers and memorygrep with superpowersHere are some useful programs I use:
console utilities/programs:
zoxide: memorizes which directories you cd into, so you can later type shorthands for them
procs: modern replacement for the ps command. basically lists your processes
neofetch/fastfetch: displays your system info in a fancy way. 99% Linux users use that
inxi: displays detailed system info but in a less fancy way. people usually attach the output of inxi -Fxz to a forum post where they need help troubleshooting
asciinema: cool program that records your terminal sessions as text files
agg: converts asciinema recordings to gif
yt-dlp: insanely powerful youtube downloader (remember to only download things you are permitted to!)
sl: ragebait when you misspell ls
yazi: fancy file manager with image previews! minimal or no configuration required
cava: audio visualizer. when you press f it cycles colors!
htop/btop: you already mentioned. task managers basically
ncdu: interactively shows disk usage per file
GUI apps:
qalculate: very powerful calculator (has both qt and gtk frontends)
gparted: probably the best gui disk management tool so far
localsend: send files locally over wifi direct
blueman: gui bluetooth manager
freetube: awesome youtube client (NOTE: against youtube terms of use!)
baobab: gui disk usage analyzer
cheese: photo taking app with funny effects
Great list! And just to add a bit:
yt-dlp is indeed insanely powerful, and works for way more than just YouTube, for both audio(music) and video. Supported sites
LocalSend is supported on all platforms, and is perfect for situations where you traditionally use a USB to move files.
Some recommendations:
baobab -> QDirStatqalculate -> speedcrunchncdu -> gdu ("I am you, but faster")I prefer lsd to ls or eza/exa (RIP exa).
thanks for suggestions. but a couple of controversial things:
i have no problems with qdirstat or gdu, so i'll give them a try. i'll maybe try speedcrunch as well
IDE:
DOOM Emacs. It's my IDE, my email client, sometimes my terminal, my calendar, my regular word editor, it's just everything I need.
NVChad. It's Neovim but with all the smart plugins as default. I prefer it over lazyvim as it just has everything I need good to go.
CLI/TUIs:
If you like watching anime than Ani-CLI is the best thing out there. has everything and you can watch whatever you want in the terminal.
Bat. It's like Cat but better.
lazygit. really great git interface that makes things easy.
cmus. easiliy the best TUI music player
yazi. my go to file manager. has everything I need, easy to theme and customize.
osxiv. straight forward image viewer
Browser:
Qutebrowser. I like using vim navigation for everything so Qutebrowser is my browser of choice. very easy to customize and configure with custom scripts. works fantastic with various password managers.
I'll list a few of my regularly-used tools, both CLI and GUI.
CLI:
ncdu: An interactive TUI variant of du, for tracing disk usage across targeted directories.podman: An alternative runtime to Docker that is arguably just better at this point. Can handle rootless containers with ease, works with SELinux, can handle Docker compose files with add-on tool podman-compose, can automatically update containers intelligently, can integrate well with SystemD, and more.mtr: Another network tool. Effectively traces network routes to a given IP. Great for diagnosing faults in latency or major packet loss.ffmpeg: A very complicated, but powerful tool for converting, manipulating video and audio files in all sorts of ways. FFMpeg can essentially be the answer to any 'do X to Y file' question.GUI:
KeepassXC: My password manager of choice. Has browser autofill integration, though requires some holepunch work to function with Flatpak browsers. Explicitly is based on local files. Does not rely on cloud providers.
I use Proton Pass and Bitwarden. How do you backup your KeePass database? Do you sync it with mobile?
It's probably not a case for everyone due to the obvious limitations, but I primarily use KeepassXC from my main workstation. I have backup scripts that periodically run for my user on said workstation that capture my Keepass database among other user files and backup to external storage, cloud storage as dictated.
For my laptops, mobile devices; I periodically push the database from either the main workstation or pull from a backup to these devices. I do not write new entries from these devices in order to avoid having to handle writeback to the main instance of my Keepass db. This can be done, but inherently starts to hinge on needing network access all the time to ensure an up-to-date copy of the DB is present as well as being explicitly a single-user db to prevent a syncing protocol from accidentally writing over new entries from any given device. Obviously, if these are important features to you, continue using Bitwarden. It is a perfectly fine solution.
Neofetch is a command line tool that prints your system information in the terminal, it is the standard way to let everyone know you're using arch
Reminded me that I messed that up somehow when I swapped from bash to zsh. Neofetch no longer prints my system info and I forgot about trying to fix it 😔
Oh, yeah. I installed fastfetch, not sure which one is better/newer.
There's also zigfetch, but that doesn't have a Nix logo :/
Fuzzy search the output from any command. The most commonly used for me is the ctrl + r hotkey for fuzzy searching in my bash history. But I have multiple scripts and aliases that utilize it.
https://cockpit-project.org/ is a webui primarily meant for servers but I find it great to get a graphical overview of both services and logs on my workstation too.
I think that's the thing that openSUSE is moving towards? I read that YaST will be deprecated in the future, but currently I think some features are only available in either of those tools. I didn't try Cockpit yet.
Here's my list
