One edits files in place, interactively. The other edits streams i.e.batch processing.

You want sed -i -f -

ed is also the precursor of sed, and of some other dozen of commands.

No, we don’t. This is a completely unrelated problem.

Keep your requirements orthogonal, people!!!

Somehow, despite being the standard it doesn’t come installed by default in any distro I’ve tried.

They all insist you use sed… that bloated thing!

To be fair, the biggest footguns are the trigraphs, and now that I tested those do require a flag in gcc.

The digraphs are just hard to search, never used operator symbols.

The examples on the meme don’t bind any variables. If those are lambdas, the Haskell version is just the ... part.

Oh, I didn’t know about digraphs at all. C++ is a really big language.

And wow, that’s a well hidden footgun.

What is happening there?

Is it about templates? I can’t find any reference for that syntax.
