/usr/bin/dpll: unrecognized option '--help'
Unknown option.
Usage: dpll [ OPTIONS ] OBJECT { COMMAND | help }
where OBJECT := { device | pin | monitor }
OPTIONS := { -V | --Version | -j | --json | -p | --pretty |
-t | --timestamp | --tshort }
Options (5)
| Option | Description | Source |
|---|
-V, --Version | Print the version of the dpll utility and exit. | man |
-j, --json | Output results in JavaScript Object Notation (JSON). | man |
-p, --pretty | When combined with -j, generates a pretty JSON output with indentation and newlines for better human readability. | man |
-t, --timestamp | When used with the monitor object, print a Timestamp: line before each received notification, in the same format used by ip monitor. | man |
--tshort | Like -t, but emits a more compact, ISO 8601 inline prefix “[YYYY-MM-DDTHH:MM:SS.uuuuuu]” in front of each notification instead of a separate Timestamp: line. | man |
