You can manage (create/open/list) notes via this tool on terminal. notes also
optionally can save your notes thanks to Git to avoid losing your notes.
notes is intended to be used nicely with other commands such as grep (or ag, rg),
rm, filtering tools such as fzf or peco and editors which can be started from
command line.
notes is developed at https://github.com/rhysd/notes-cli. If you're seeing a bug or having a feature request,
please create a new issue. Pull requests are more than welcome.`
