A much less readable and maintainable version of agama's solution which is guaranteed to make whoever inherits the code mutter under their breath:
Code:
awk -F_ '!a[$1] && !a[$2] && ++a[$1] && ++a[$2]' file

GIT-PACK-REDUNDANT(1)						    Git Manual						     GIT-PACK-REDUNDANT(1)

NAME
git-pack-redundant - Find redundant pack files SYNOPSIS
git pack-redundant [ --verbose ] [ --alt-odb ] < --all | .pack filename ... > DESCRIPTION
This program computes which packs in your repository are redundant. The output is suitable for piping to xargs rm if you are in the root of the repository. git pack-redundant accepts a list of objects on standard input. Any objects given will be ignored when checking which packs are required. This makes the following command useful when wanting to remove packs which contain unreachable objects. git fsck --full --unreachable | cut -d ' ' -f3 | git pack-redundant --all | xargs rm OPTIONS
--all Processes all packs. Any filenames on the command line are ignored. --alt-odb Don't require objects present in packs from alternate object directories to be present in local packs. --verbose Outputs some statistics to stderr. Has a small performance penalty. SEE ALSO
git-pack-objects(1) git-repack(1) git-prune-packed(1) GIT
Part of the git(1) suite Git 1.7.10.4 11/24/2012 GIT-PACK-REDUNDANT(1)
