NAME
----
git-cat-file - Provide content or type and size information for repository objects


SYNOPSIS
--------
[verse]
'git cat-file' (-t | -s | -e | -p | <type> | --textconv ) <object>
'git cat-file' (--batch | --batch-check) < <list-of-objects>

DESCRIPTION
-----------
In its first form, the command provides the content or the type of an object in
the repository. The type is required unless '-t' or '-p' is used to find the
object type, or '-s' is used to find the object size, or '--textconv' is used
(which implies type "blob").

In the second form, a list of objects (separated by linefeeds) is provided on
stdin, and the SHA-1, type, and size of each object is printed on stdout.

OPTIONS
-------
<object>::
	The name of the object to show.
	For a more complete list of ways to spell object names, see
	the "SPECIFYING REVISIONS" section in linkgit:gitrevisions[7].

-t::
	Instead of the content, show the object type identified by
	<object>.

-s::
	Instead of the content, show the object size identified by
	<object>.

-e::
	Suppress all output; instead exit with zero status if <object>
	exists and is a valid object.

-p::
	Pretty-print the contents of <object> based on its type.

<type>::
	Typically this matches the real type of <object> but asking
	for a type that can trivially be dereferenced from the given
	<object> is also permitted.  An example is to ask for a
	"tree" with <object> being a commit object that contains it,
	or to ask for a "blob" with <object> being a tag object that
	points at it.

--textconv::
	Show the content as transformed by a textconv filter. In this case,
	<object> has be of the form <treeish>:<path>, or :<path> in order
	to apply the filter to the content recorded in the index at <path>.

--batch::
	Print the SHA-1, type, size, and contents of each object provided on
	stdin. May not be combined with any other options or arguments.

--batch-check::
	Print the SHA-1, type, and size of each object provided on stdin. May not
	be combined with any other options or arguments.

--batch-disk-sizes::
	Like `--batch-check`, but print the on-disk size of each object
	(including zlib and delta compression) rather than the object's
	true size. May not be combined with any other options or
	arguments.
+
NOTE: The on-disk size reported is accurate, 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 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 will be reported.


OUTPUT
------
If '-t' is specified, one of the <type>.

If '-s' is specified, the size of the <object> in bytes.

If '-e' is specified, no output.

If '-p' is specified, the contents of <object> are pretty-printed.

If <type> is specified, the raw (though uncompressed) contents of the <object>
will be returned.

If '--batch' is specified, output of the following form is printed for each
object specified on stdin:

------------
<sha1> SP <type> SP <size> LF
<contents> LF
------------

If '--batch-check' is specified, output of the following form is printed for
each object specified on stdin:

------------
<sha1> SP <type> SP <size> LF
------------

For both '--batch' and '--batch-check', output of the following form is printed
for each object specified on stdin that does not exist in the repository:

------------
<object> SP missing LF
------------
