Every time such a list is posted, it tends to generate a lot of debate, but I do think there is at least 2 tools that are really a good addition to any terminal :

`fd`: first I find that the argument semantic is way better than `find`, but that is more a bonus than a real killer feature. Now, it being much, much faster than `find` on most setup, I would consider a valuable feature. But the killer feature for me is the `-x` argument. It allows calling another command on the individual search result, which `find` can also do with `xargs` and co. But `fd` provide a very nice placeholder syntax[0], which remove the need to mess with `basename` and co. to parse the filename and make a new one, and it executes in parallel. For example, it makes converting a batch of image a fast and readable one line : `fd -e jpg -x cjxl {} {.}.jxl`

`rg` a.k.a `ripgrep` : Honestly it is just about the speed. It is so much faster than `grep` when searching through a directory, it opens up a lot of possibilities. Like, searching for `isLoading` on my frontend (~3444 files) is instant with rg (less than 0.10s) but takes a few minutes with grep.

But there is one other thing that I really like with `ripgrep` and that I think should be a feature of any "modern" CLI tool : It can format its output in JSON. Not that I am a big fan of JSON, but at least it is a well-defined exchange format. "Classic" CLI tool just output in a "human-readable" format which might just happen to be "machine-readable" if you mess with `awk` and `sed` enough. But it makes piping and scripting just that much more annoying and error & bug prone. Being able to output json, `jq` it and feed it to the next tool is so much better and feel like the missing chain of the terminal.

The big advantage of the CLI is that it is composable and scriptable by default. But it is missing a common exchange format to pass data, and this is what you have to wrangle with a lot of time when scripting. Having json, never mind all the gripes I have with this format, really join everything together.

Also, honorable mention for `zellij` which I find to be a much saner UX-wise alternative to `tmux`, and the `helix` text editor, which for me is neo-vim but with, again, a better UX (especially for beginner) and a lot more battery included feature while remaining faster (IMEX) than nvim with matching plugin for feature-parity.

EDIT: I would also add difftastic ( https://github.com/Wilfred/difftastic ) which is a syntax aware diff tool. I don't use it much, but it does makes some diff so so much easier to read.
