Ask HN: What commandline tools do you use to take notes?

I’ve used https://jrnl.sh/en/stable/ in the past and enjoyed it

Vanilla vim with Markdown syntax.

vim-wiki for cli notes.

Zim-wiki otherwise.

I have been kind of unimpressed with vimwiki, so I used to just use my own folder structure for categories and create markdown/rst files for somewhat-formatted notes.

At the moment I'm using Zim wiki, which is a graphical program.

does "echo" count ? I do "echo mynote123 >> notes" occasionally when working with a codebase especially a novel one.

Then emacs org-mode for more structured notes.
