OPTIONS
-------
<object>.
-e::
- Suppress all output; instead exit with zero status if <object>
- exists and is a valid object.
+ Exit with zero status if <object> exists and is a valid
+ object. If <object> is of an invalid format exit with non-zero and
+ emits an error on stderr.
-p::
Pretty-print the contents of <object> based on its type.
Print object information and contents for each object provided
on stdin. May not be combined with any other options or arguments
except `--textconv` or `--filters`, in which case the input lines
- also need to specify the path, separated by white space. See the

section `BATCH OUTPUT` below for details.
--batch-check::
Print object information for each object provided on stdin. May
not be combined with any other options or arguments except
`--textconv` or `--filters`, in which case the input lines also
- need to specify the path, separated by white space. See the

--batch-all-objects::
buffering; this is much more efficient when invoking
`--batch-check` on a large number of objects.
+--unordered::
+ When `--batch-all-objects` is in use, visit objects in an
+ order which may be more efficient for accessing the object
+ contents than hash order. The exact details of the order are
+ unspecified, but if you do not require a specific order, this
+ should generally result in faster output, especially with
+ `--batch`. Note that `cat-file` will still show each object
+ only once, even if it is stored multiple times in the
+ repository.
+
--allow-unknown-type::
Allow -s or -t to query broken/corrupt objects of unknown type.
If `-s` is specified, the size of the <object> in bytes.
-If `-e` is specified, no output.
+If `-e` is specified, no output, unless the <object> is malformed.
If `-p` is specified, the contents of <object> are pretty-printed.
<object> SP missing LF
------------
+If a name is specified that might refer to more than one object (an ambiguous short sha), then `cat-file` will ignore any custom format and print:

If --follow-symlinks is used, and a symlink in the repository points
outside the repository, then `cat-file` will ignore any custom format
and print:
