NAME

       git-show-index - Show packed archive index

SYNOPSIS

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

DESCRIPTION

       Read the .idx file for a Git packfile (created with git-pack-objects(1) or 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 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..

           Note: At present, there is no interoperability between SHA-256 repositories and SHA-1
           repositories.

       Historically, we warned that SHA-256 repositories may later need backward incompatible
       changes when we introduce such interoperability features. Today, we only expect compatible
       changes. Furthermore, if such changes prove to be necessary, it can be expected that
       SHA-256 repositories created with today’s Git will be usable by future versions of Git
       without data loss.
