GIT-SHOW-INDEX(1)              Git Manual              GIT-SHOW-INDEX(1)

NAME top

       git-show-index - Show packed archive index

SYNOPSIS top

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

DESCRIPTION top

       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 top

       --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..

           THIS OPTION IS EXPERIMENTAL! SHA-256 support is experimental
           and still in an early stage. A SHA-256 repository will in
           general not be able to share work with "regular" SHA-1
           repositories. It should be assumed that, e.g., Git internal
           file formats in relation to SHA-256 repositories may change
           in backwards-incompatible ways. Only use
           --object-format=sha256 for testing purposes.
