# [PATCH] Add git-pack-ls-objects tool 3 messages from 2006-01-22 to 2006-01-22. Participants: Petr Baudis, Junio C Hamano. Thread: https://gitlist.dev/t/3124 ## Petr Baudis, 2006-01-22 02:27 Subject: [PATCH] Add git-pack-ls-objects tool Message-ID: <20060122022711.16333.93404.stgit@machine.or.cz> URL: https://gitlist.dev/e/20060122022711.16333.93404.stgit%40machine.or.cz ``` This tool takes pack index on stdin and produces the list of indexed objects on stdout. Very simple, but I've been always somewhat nervous that I cannot list all (even unreferenced) objects in a repository, and in a given pack in particular. The immediate use will be in the git-count-objects script, but I can imagine it being useful also in various troubleshooting situations.

Yes, I just had no idea this existed. ;) -- Petr "Pasky" Baudis Stuff: http://pasky.or.cz/ Of the 3 great composers Mozart tells us what it's like to be human, Beethoven tells us what it's like to be Beethoven and Bach tells us what it's like to be the universe. -- Douglas Adams ```
