NAME top
git-show-index - Show packed archive index
SYNOPSIS top
_git show-index_ [--object-format=<hash-algorithm>] < <pack-idx-file>
DESCRIPTION top
Read the **.idx** file for a Git packfile (created with
[git-pack-objects(1)](../man1/git-pack-objects.1.html) or [git-index-pack(1)](../man1/git-index-pack.1.html)) 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)](../man1/git-verify-pack.1.html). 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..
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.
