If you use fish, have a look at `string replace` as a built-in and related [0].

Regardless of the appeal to unix philosophy in their docs, sd has never stuck with me because it doesn't natively support replace across a project/ multiple files, and that's what you always want to do. Instead I pipe `rg -R --json` output into a script (rg does do replacement, but only on the stdout, not in-place)

    find -exec sd before after \;

The sed extraction example is more complicated than it needs to be:

    echo "sample with /path/" | sed -E 's|.*(/.*/)|\1|g'

The search/replace separator doesn't have to be '/'.

I can't see myself using this for a performance bump given that I already know vi, thus sed expressions.

  sed ':a;N;$!ba;s/\n/,/g'

For cases I am not 100% sure I want to replace all occurrences, I prefer scooter: https://github.com/thomasschafer/scooter

I'm partial to f2.
