+`cleos` and `leap-util` offer a substantial amount of functionality. Consider using bash's autocompletion support which makes it easier to discover all their various options.

+If building from source install the `build/programs/cleos/bash-completion/completions/cleos` and `build/programs/leap-util/bash-completion/completions/leap-util` files to your bash-completion directory. Refer to [bash-completion's documentation](https://github.com/scop/bash-completion#faq) on the possible install locations.
