I have a one-liner bash alias that stores whatever I feed it into a file by todays date, alias "note"="echo $1 >> ~/.notes/`date+'%Y-%m-%d'`.note" So you end up with a folder of files formatted like this 2021-11-02.note. Then to view them I either just cat it, or jump in to a text editor. I have an alias to cat todays .note alias "notes"="cat ~/.notes/`date+'%Y-%m-%d'`.note" I have sometimes considered fleshing it out, but like other commenters have pointed out, it's the habit more than the tool that makes it useful. Simple is key.
