=================

NAME
----
git-show-index - Show packed archive index


SYNOPSIS
--------
[verse]
'git show-index' [--object-format=<hash-algorithm>]


DESCRIPTION
-----------
Read the `.idx` file for a Git packfile (created with
linkgit:git-pack-objects[1] or linkgit:git-index-pack[1]) from the
standard input, and dump its contents. The output consists of one object
per line, with each line containing two or three space-separated
columns:

  - the first column is the offset in bytes of the object within the
    corresponding packfile

  - the second column is the object id of the object

  - if the index version is 2 or higher, the third column contains the
    CRC32 of the object data

The objects are output in the order in which they are found in the index
file, which should be (in a correctly constructed file) sorted by object
id.

Note that you can get more information on a packfile by calling
linkgit:git-verify-pack[1]. However, as this command considers only the
index file itself, it's both faster and more flexible.

OPTIONS
-------

--object-format=<hash-algorithm>::
	Specify the given object format (hash algorithm) for the index file.  The
	valid values are 'sha1' and (if enabled) 'sha256'.  The default is the
	algorithm for the current repository (set by `extensions.objectFormat`), or
	'sha1' if no value is set or outside a repository..
