GIT-CAT-FILE(1)                   Git Manual                   GIT-CAT-FILE(1)



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

SYNOPSIS
       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 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
