Speaking of faster coreutils replacements, I highly recommend ripgrep (rg) and fd-find (fd), which are Rust-based, incompatible replacements for grep and find.

I know I'm way behind the popularity curve* (they're already in debian-stable, for crying out loud); but for the benefit of anyone even more out of the loop than myself, do check these out. The speed increase is amazing: a significant quality-of-life improvement, essentially for free**. Particularly if you're on a modern NVME SSD and not utilizing it properly. (Incidentally, did you know the "t" in coreutil's "tar" stands for magnetic [t]ape?")

* (The now-top reply to this comment says 'ag' is even superior to 'rg', and they're probably right, but I had no clue about it! I did say I'm ignorant!)

**(Might have some cost if you're heavily invested in power-user syntax of the GNU or BSD versions, in which case incompatibility has a price).

Okay, call me lazy. Not for ripgrep, installed it early from sources. However your fdfind (fd) mention made me curious. Thought I give it an apt install on Ubtunu 20.04 LTS but dead end. So perhaps in debian-stable but not in Ubuntu. Just saying, so I can feel less out of the loop ;)

Upstream says Ubuntu's package is 'fd-find' (and the executable is 'fdfind' -- both renamed from upstream's 'fd' because of a name collision with an unrelated Debian package. If you don't care about that one, you can safely alias fd="fdfind").

(I've edited my first comment in response to this reply: I originally wrote "fdfind". (For a comment about regexp tools, this is a uniquely, hilariously stupid oversight. Sorry!)).
