git-show-index(1) Git Manual git-show-index(1)
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:
o the first column is the offset in bytes of the object within the
corresponding packfile
o the second column is the object id of the object
o 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.
