if youre into zettlekasten, and you prefer doing things in a more unix,

or CLI way, a simple ripgrep in your notes directory with a tag keyword

will show you a list of all associated notes. you can even pair it with

fzf to get an interactive list that will open a selected note in

$EDITOR. i.e. you dont need obsidian. use it if you like, but basic unix

tools is all you need.
