objectsize::
The size of the object (the same as 'git cat-file -s' reports).
-
+ Append `:disk` to get the size, in bytes, that the object takes up on
+ disk. See the note about on-disk sizes in the `CAVEATS` section below.
objectname::
The object name (aka SHA-1).
For a non-ambiguous abbreviation of the object name append `:short`.
For an abbreviation of the object name with desired length append
`:short=<length>`, where the minimum length is MINIMUM_ABBREV. The
length may be exceeded to ensure unique object names.
+deltabase::
+ This expands to the object name of the delta base for the
+ given object, if it is stored as a delta. Otherwise it
+ expands to the null object name (all zeroes).
upstream::
The name of a local ref which can be considered ``upstream''
`:lstrip` and `:rstrip` options in the same way as `refname`
above.
+worktreepath::
+ The absolute path to the worktree in which the ref is checked
+ out, if it is checked out in any linked worktree. Empty string
+ otherwise.
+
In addition to the above, for commit and tag objects, the header
field names (`tree`, `parent`, `object`, `type`, and `tag`) can
be used to specify the value in the header field.
git for-each-ref --format="%(refname)%(if)%(authorname)%(then) Authored by: %(authorname)%(end)"

+CAVEATS
+-------
+
+Note that the sizes of objects on disk are reported accurately, but care
+should be taken in drawing conclusions about which refs or objects are
+responsible for disk usage. The size of a packed non-delta object may be
+much larger than the size of objects which delta against it, but the
+choice of which object is the base and which is the delta is arbitrary
+and is subject to change during a repack.
+
+Note also that multiple copies of an object may be present in the object
+database; in this case, it is undefined which copy's size or delta base
+will be reported.
