git-pack-refs(1) ================ NAME ---- git-pack-refs - Pack heads and tags for efficient repository access SYNOPSIS -------- [verse] 'git pack-refs' [--all] [--no-prune] [--auto] [--include <pattern>] [--exclude <pattern>] DESCRIPTION ----------- Traditionally, tips of branches and tags (collectively known as 'refs') were stored one file per ref in a (sub)directory under `$GIT_DIR/refs` directory. While many branch tips tend to be updated often, most tags and some branch tips are never updated. When a repository has hundreds or thousands of tags, this one-file-per-ref format both wastes storage and hurts performance. This command is used to solve the storage and performance problem by storing the refs in a single file, `$GIT_DIR/packed-refs`. When a ref is missing from the traditional `$GIT_DIR/refs` directory hierarchy, it is looked up in this file and used if found. Subsequent updates to branches always create new files under `$GIT_DIR/refs` directory hierarchy. A recommended practice to deal with a repository with too many refs is to pack its refs with `--all` once, and occasionally run `git pack-refs`. 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 ------- include::pack-refs-options.adoc[] BUGS ---- Older documentation written before the packed-refs mechanism was introduced may still say things like ".git/refs/heads/<branch> file exists" when it means "branch <branch> exists".
