href="#_description"></a>DESCRIPTION</h2> <div class="sectionbody"> <div class="paragraph"> <p>Traditionally, tips of branches and tags (collectively known as <em>refs</em>) were stored one file per ref in a (sub)directory under <code>$GIT_DIR/refs</code> directory. While many branch tips tend to be updated often, most tags and some branch tips are never updated. When a repository has hundreds or thousands of tags, this one-file-per-ref format both wastes storage and hurts performance.</p> </div> <div class="paragraph"> <p>This command is used to solve the storage and performance problem by storing the refs in a single file, <code>$GIT_DIR/packed-refs</code>. When a ref is missing from the traditional <code>$GIT_DIR/refs</code> directory hierarchy, it is looked up in this file and used if found.</p> </div> <div class="paragraph"> <p>Subsequent updates to branches always create new files under <code>$GIT_DIR/refs</code> directory hierarchy.</p> </div> <div class="paragraph"> <p>A recommended practice to deal with a repository with too many refs is to pack its refs with <code>--all</code> once, and occasionally run <code>git pack-refs</code>. Tags are by definition stationary and are not expected to change. Branch heads will be packed with the initial <code>pack-refs --all</code>, but only the currently active branch heads will become unpacked, and the next <code>pack-refs</code> (without <code>--all</code>) will leave them unpacked.</p> </div> </div> </div> <div class="sect1"> <h2 id="_options"><a class="anchor" href="#_options"></a>OPTIONS</h2> <div class="sectionbody"> <div class="dlist"> <dl> <dt class="hdlist1" id="Documentation/git-pack-refs.txt---all"> <a class="anchor" href="#Documentation/git-pack-refs.txt---all"></a>--all </dt> <dd> <p>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 all refs to be packed as well, with the exception of hidden refs, broken refs, and symbolic refs. Useful for a repository with many branches of historical interests.</p> </dd> <dt class="hdlist1" id="Documentation/git-pack-refs.txt---no-prune"> <a class="anchor" href="#Documentation/git-pack-refs.txt---no-prune"></a>--no-prune </dt> <dd> <p>The command usually removes loose refs under <code>$GIT_DIR/refs</code> hierarchy after packing them.

Repetitions of this option accumulate inclusion patterns. If a ref is both included in <code>--include</code> and <code>--exclude</code>, <code>--exclude</code> takes precedence. Using <code>--include</code> will preclude all tags from being included by default. Symbolic refs and broken refs will never be packed. When used with <code>--all</code>, it will be a noop.
