Linux

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.

Underrated or not widely known?

I love lazygit and I'm still surprised at how many people are shocked when they see it for the first time. Not exactly a command, but a very handy text UI tool.

For more elementary tools, I can't believe how many people know about ! and ctrl+r who don't also know about fc and edit-and-execute-command.

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

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

I use fuck to fix typos

Pandoc, FFMpeg, ImageMagick

I use node as a calculator a lot. It can be dangerous, because it suffers from floating point errors, but it’s generally more powerful than a calculator if you know the Math lib well.

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.

degit is a tool that will check out a git repo (or a specific branch or commit), but not set it up as a git repo. Basically just downloading a specific commit to a directory.

• awk
• the (usually rust-based) coreutils "alternatives" like bat, fd, eza, procs
• trash-put (rm with trash integration. But beware that it also operates on directories by default, which rm only does with -r. There should be an option to change that behavior but there isn't. Don't alias rm to this)
• wl-copy/paste (or the older one for X11, 'xclip' IIRC. Enables you to do stuff like "cat image.jpg | wl-copy" to copy it to the clipboard. Best alias it to something shorter)
• xdg-open (open the file using your associated program for that file type. Alias to "o" or so)
• pass (awesome password manager, when you have a GPG key pair. Even better in combination with e.g. wofi)
• notify-send (to send GUI notifications from shell scripts)
• ledger (plain-text accounting software. If you use Emacs you should take a look at this as it's written by an Emacs dev, and has good integration of course)
• nc
• nohup

I really enjoy erdtree a ls replacement

vd (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.

Bat, a cat alternative.

Lsd, an ls alternative.

Procs, a ps alternative.

Renane, because it's great.

grep goes crazy if you know your regex
