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 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.
