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
