NAME

       git-pack-refs - Pack heads and tags for efficient repository access

SYNOPSIS

       git pack-refs [--all] [--no-prune]

DESCRIPTION

       Traditionally, tips of branches and tags (collectively known as refs) were stored one file
       per ref under $GIT_DIR/refs directory. While many branch tips tend to be updated often,
       most tags and some branch tips are never updated. When a repository has hundreds or
       thousands of tags, this one-file-per-ref format both wastes storage and hurts performance.

       This command is used to solve the storage and performance problem by stashing the refs in
       a single file, $GIT_DIR/packed-refs. When a ref is missing from the traditional
       $GIT_DIR/refs hierarchy, it is looked up in this file and used if found.

       Subsequent updates to branches always create new files under $GIT_DIR/refs hierarchy.

       A recommended practice to deal with a repository with too many refs is to pack its refs
       with --all --prune once, and occasionally run git pack-refs --prune. Tags are by
       definition stationary and are not expected to change. Branch heads will be packed with the
       initial pack-refs --all, but only the currently active branch heads will become unpacked,
       and the next pack-refs (without --all) will leave them unpacked.

OPTIONS

       --all
           The command by default packs all tags and refs that are already packed, and leaves
           other refs alone. This is because branches are expected to be actively developed and
           packing their tips does not help performance. This option causes branch tips to be
           packed as well. Useful for a repository with many branches of historical interests.

       --no-prune
           The command usually removes loose refs under $GIT_DIR/refs hierarchy after packing
           them. This option tells it not to.
