NAME
----
git-cat-file - Provide content or type and size information for repository objects
SYNOPSIS
--------
[verse]
'git cat-file' (-t | -s | -e | -p | <type>) <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.
In the second form, a list of objects (separated by linefeeds) is provided on
stdin, and the SHA1, 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:git-rev-parse[1].
-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.
--batch::
Print the SHA1, type, size, and contents of each object provided on
stdin. May not be combined with any other options or arguments.
--batch-check::
Print the SHA1, type, and size of each object provided on stdin. May not
be combined with any other options or arguments.
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
