.SH "NAME"
git-cat-file \- Provide content or type and size information for repository objects
.SH "SYNOPSIS"
.sp
.nf
\fIgit cat\-file\fR (\-t | \-s | \-e | \-p | <type> | \-\-textconv ) <object>
\fIgit cat\-file\fR (\-\-batch | \-\-batch\-check) < <list\-of\-objects>
.fi
.sp
.SH "DESCRIPTION"
.sp
In its first form, the command provides the content or the type of an object in the repository\&. The type is required unless \fI\-t\fR or \fI\-p\fR is used to find the object type, or \fI\-s\fR is used to find the object size, or \fI\-\-textconv\fR is used (which implies type "blob")\&.
.sp
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\&.
.SH "OPTIONS"
.PP
<object>
.RS 4
The name of the object to show\&. For a more complete list of ways to spell object names, see the "SPECIFYING REVISIONS" section in
\fBgitrevisions\fR(7)\&.
.RE
.PP
\-t
.RS 4
Instead of the content, show the object type identified by <object>\&.
.RE
.PP
\-s
.RS 4
Instead of the content, show the object size identified by <object>\&.
.RE
.PP
\-e
.RS 4
Suppress all output; instead exit with zero status if <object> exists and is a valid object\&.
.RE
.PP
\-p
.RS 4
Pretty\-print the contents of <object> based on its type\&.
.RE
.PP
<type>
.RS 4
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\&.
.RE
.PP
\-\-textconv
.RS 4
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>\&.
.RE
.PP
\-\-batch
.RS 4
Print the SHA1, type, size, and contents of each object provided on stdin\&. May not be combined with any other options or arguments\&.
.RE
.PP
\-\-batch\-check
.RS 4
Print the SHA1, type, and size of each object provided on stdin\&. May not be combined with any other options or arguments\&.
.RE
.SH "OUTPUT"
.sp
If \fI\-t\fR is specified, one of the <type>\&.
.sp
If \fI\-s\fR is specified, the size of the <object> in bytes\&.
.sp
If \fI\-e\fR is specified, no output\&.
.sp
If \fI\-p\fR is specified, the contents of <object> are pretty\-printed\&.
.sp
If <type> is specified, the raw (though uncompressed) contents of the <object> will be returned\&.
.sp
If \fI\-\-batch\fR is specified, output of the following form is printed for each object specified on stdin:
.sp
.if n \{\
.RS 4
.\}
.nf
<sha1> SP <type> SP <size> LF
<contents> LF
.fi
.if n \{\
.RE
.\}
.sp
.sp
If \fI\-\-batch\-check\fR is specified, output of the following form is printed for each object specified on stdin:
.sp
.if n \{\
.RS 4
.\}
.nf
<sha1> SP <type> SP <size> LF
.fi
.if n \{\
.RE
.\}
.sp
.sp
For both \fI\-\-batch\fR and \fI\-\-batch\-check\fR, output of the following form is printed for each object specified on stdin that does not exist in the repository:
.sp
.if n \{\
.RS 4
.\}
.nf
<object> SP missing LF
.fi
.if n \{\
.RE
.\}
.sp
