`options` command to show all the aliases and functions offered by plugins you have installed via oh-my-zsh

options.zsh

function options() {
    PLUGIN_PATH="$HOME/.oh-my-zsh/plugins/"
    for plugin in $plugins; do
        echo "\n\nPlugin: $plugin"; grep -r "^function \w*" $PLUGIN_PATH$plugin | awk '{print $2}' | sed 's/()//'| tr '\n' ', '; grep -r "^alias" $PLUGIN_PATH$plugin | awk '{print $2}' | sed 's/=.*//' |  tr '\n' ', '
    done
}

I have a bug with your script. Also you might just check if $ZSH is .dotfiles or the $ZSH directory

It's in the .oh-my-zsh/custom/plugins/ directory.
