This will report the device identifiers which can be queried from the owner of the control socket. .TP .BI "\-i, \-\-device\-id=" id Act on only the specified device. If no devices are explicitly specified then the default is to act upon all of them. This option may be passed multiple times to act on some subset of the available devices. The \fIid\fP must be an identifier name as reported by \fBbbctl\ \-\-scan\fP, you cannot use device logical or physical addresses here. .TP .B \-b, \-\-bin\-freq Report the 8-bit symbol frequencies. .TP .B \-B, \-\-bin\-freq16 Report the 16-bit symbol frequencies. .TP .B " \-\-bin\-count" Report the 8-bit symbol counts. Similar to \fB\-\-bin\-freq\fP except the bins are reported in symbol order instead of sorted by frequency. .TP .B " \-\-bin\-count16" Report the 16-bit symbol counts. Similar to \fB\-\-bin\-freq16\fP except the bins are reported in symbol order instead of sorted by frequency. .TP .BI " \-\-first=" n Show only the first \fIn\fP results. Useful when you don't want to actually see all 65 thousand entries for the 16-bit bins. The default (if neither this nor the \fB\-\-last\fP option are specified) is to report everything in its full glory. Don't say I didn't warn you. .TP .BI " \-\-last=" n Show only the last \fIn\fP results. Useful when you don't want to actually see all 65 thousand entries for the 16-bit bins. If used together with the \fB\-\-first\fP option, then both the requested head and tail of the results will be shown. .TP .B \-r, \-\-bit\-runs Report on runs of consecutive bits. .TP .B \-S, \-\-stats Report general QA statistics. .TP .BI "\-c, \-\-control\-socket=" path The filesystem path for the service control socket to query. This can belong to any process that supports the BitBabbler control socket interface and for which the user running \fBbbctl\fP has permission to connect to. An address of the form \fItcp:host:port\fP may be used if the control socket is bound to a TCP port rather than a unix domain socket path. The \fIhost\fP part can be a DNS hostname or address literal. If an IPv6 address literal is used it should be enclosed in square brackets (e.g. tcp:[::1]:2020 to bind to port 2020 on the local IPv6 interface). The \fIport\fP can be a port number or a service name (as defined in \fI/etc/services\fP or other system name-service databases which are queried by \fBgetaddrinfo\fP(3)). .TP .BI "\-V, \-\-log\-verbosity=" n Change the logging verbosity of the control socket owner. .TP .B \-v, \-\-verbose Make more noise about what is going on internally. It may be passed multiple times to get swamped with even more information. .TP .B \-?, \-\-help Show a shorter version of all of this, which may fit on a single page. .TP .B " \-\-version" Report the \fBbbctl\fP release version. .SH FILES .TP .I /var/run/bit\-babbler/seedd.socket The default control socket path if not explicitly specified. .SH SEE ALSO .BR seedd (1). .SH AUTHOR .B seedd was written by Ron .
