The "describe" command:

Usage: fossil describe ?VERSION? ?OPTIONS?

Provide a description of the given VERSION by showing a non-propagating tag of the youngest tagged ancestor, followed by the number of commits since that, and the short hash of VERSION. Only tags applied to a single check-in are considered.

If no VERSION is provided, describe the currently checked-out version.

If VERSION and the found ancestor refer to the same commit, the last two components are omitted, unless --long is provided. When no fitting tagged ancestor is found, show only the short hash of VERSION.

Options:

--digits

Display so many hex digits of the hash (default: the larger of 6 and the 'hash-digit' setting)

-d|--dirty

Show whether there are changes to be committed

--long

Always show all three components

--match GLOB

Consider only non-propagating tags matching GLOB
