I can do one better: Just learn to use the standard unix tools directly. If you keep stacking wrappers upon wrappers and grow to depend on them you will be totally lost once you have to work on another machine. It also makes it easier to e.g. replace grep by fzf.

For reference:

    kb list -> find
    kb list foo -> find | grep foo
    kb edit --title "git" --category "cheatsheet" -> vim cheatsheet/git
    kb delete --id 1 -> rm path/to/file
    kb grep foo -> grep -r foo

You are right, but what about having a nicer output list? What about having metadata associated to files such as author, status and especially tags?

Also, what about being cross-platform and able to run on Windows?

What about instead having custom templates to apply to the files I desire?

alias rg="rg" might be more flexible as it allows you to specifify a root folder to search in as well as other options.

edit: The previous sentence is a joke. This should not take away the usefulness and polish of kb.

Try "$@" instead of $1, for multi-word queries.
