According to [[https://gitweb.torproject.org/torspec.git/tree/control-spec.txt|control-spec.txt]]: > The OptionPrefix form indicates a number of options beginning with the prefix. So if `config/*` is listed, other options beginning with `config/` will work, but `config/*` itself is not an option. In Nyx and `tor-prompt` interpreters' `/help`, if the format `Option/*` is used to name a group of options (each of them is still described separately), it must be done for everything. However, e.g., we have many options inside `accounting`, but key `accounting/*` doesn't exist: ``` accounting/bytes - Number of bytes read/written so far in the accounting interval. accounting/bytes-left - Number of bytes left to write/read so far in the accounting interval. accounting/enabled - Is accounting currently enabled? accounting/hibernating - Are we hibernating or awake? accounting/interval-end - Time when the accounting period ends. accounting/interval-start - Time when the accounting period starts. accounting/interval-wake - Time to wake up in this accounting period. ``` Compare it with: ``` config/* - Current configuration values. config/defaults - List of default values for configuration options. See also config/names config/names - List of configuration options, types, and documentation. ``` If grouping syntax is used, it should be used everywhere (for all groups) or nowhere. Otherwise, it is confusing, because for many other options the syntax `option/*` implies that something not listed here (in list of options) should be substituted (e.g. fingerprint of a relay, IP address, etc.). P.S. At first glance it looks like Nyx controller interpreter's bug, but atagar [[https://trac.torproject.org/projects/tor/ticket/28300#comment:5|says]] that it is taken literally from `control-spec.txt`. Initially it was reported in [[comment](https://trac.torproject.org/projects/tor/ticket/28300#comment:6|this)]. Separate ticket was created because of [[suggestion](https://trac.torproject.org/projects/tor/ticket/28676#comment:8|teor's)]. **Trac**: **Username**: wagon
