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
