<h1>knife download<a class="headerlink" href="#knife-download" title="Permalink to this headline">¶</a></h1>
<p>The <strong>knife download</strong> subcommand is used to download roles, cookbooks, environments, nodes, and data bags from the server to the current working directory. It can be used to back up data on the server, inspect the state of one or more files, or to extract out-of-process changes users may have made to files on the server, such as if a user made a change that bypassed version source control. This subcommand is often used in conjunction with <tt class="docutils literal"><span class="pre">knife</span> <span class="pre">diff</span></tt>, which can be used to see exactly what changes will be downloaded, and then <tt class="docutils literal"><span class="pre">knife</span> <span class="pre">upload</span></tt>, which does the opposite of <tt class="docutils literal"><span class="pre">knife</span> <span class="pre">download</span></tt>.</p>
<div class="section" id="syntax">
<h2>Syntax<a class="headerlink" href="#syntax" title="Permalink to this headline">¶</a></h2>

<p>This subcommand has the following options:</p>
<dl class="docutils">
<dt><tt class="docutils literal"><span class="pre">--chef-repo-path</span> <span class="pre">PATH</span></tt></dt>
<dd>The path to the chef-repo. This setting will override the default path to the chef-repo. Default: same as specified by <tt class="docutils literal"><span class="pre">chef_repo_path</span></tt> in config.rb.</dd>
<dt><tt class="docutils literal"><span class="pre">--concurrency</span></tt></dt>
<dd>The number of allowed concurrent connections. Default: <tt class="docutils literal"><span class="pre">10</span></tt>.</dd>

<dd>The version of a cookbook to be downloaded.</dd>
<dt><tt class="docutils literal"><span class="pre">--[no-]force</span></tt></dt>
<dd>Use <tt class="docutils literal"><span class="pre">--force</span></tt> to download files even when the file on the hard drive is identical to the object on the server (role, cookbook, etc.). By default, files are compared to see if they have equivalent content, and local files are only overwritten if they are different. Default: <tt class="docutils literal"><span class="pre">--no-force</span></tt>.</dd>
<dt><tt class="docutils literal"><span class="pre">-n</span></tt>, <tt class="docutils literal"><span class="pre">--dry-run</span></tt></dt>
<dd>Indicates that no action is taken and that results are only printed out. Default: <tt class="docutils literal"><span class="pre">false</span></tt>.</dd>
<dt><tt class="docutils literal"><span class="pre">--[no-]diff</span></tt></dt>
<dd>Indicates that only new and modified files will be downloaded. Set to <tt class="docutils literal"><span class="pre">false</span></tt> to download all files. Default: <tt class="docutils literal"><span class="pre">--diff</span></tt>.</dd>
<dt><tt class="docutils literal"><span class="pre">--[no-]recurse</span></tt></dt>
<dd>Use <tt class="docutils literal"><span class="pre">--no-recurse</span></tt> to disable downloading a directory recursively. Default: <tt class="docutils literal"><span class="pre">--recurse</span></tt>.</dd>
<dt><tt class="docutils literal"><span class="pre">--[no-]purge</span></tt></dt>
<dd>Use <tt class="docutils literal"><span class="pre">--purge</span></tt> to delete local files and directories that do not exist on the server. By default, if a role, cookbook, etc. does not exist on the server, the local file for said role will be left alone and NOT deleted. Default: <tt class="docutils literal"><span class="pre">--no-purge</span></tt>.</dd>
<dt><tt class="docutils literal"><span class="pre">--repo-mode</span> <span class="pre">MODE</span></tt></dt>
<dd>The layout of the local chef-repo. Possible values: <tt class="docutils literal"><span class="pre">static</span></tt>, <tt class="docutils literal"><span class="pre">everything</span></tt>, or <tt class="docutils literal"><span class="pre">hosted_everything</span></tt>. Use <tt class="docutils literal"><span class="pre">static</span></tt> for just roles, environments, cookbooks, and data bags. By default, <tt class="docutils literal"><span class="pre">everything</span></tt> and <tt class="docutils literal"><span class="pre">hosted_everything</span></tt> are dynamically selected depending on the server type. Default: <tt class="docutils literal"><span class="pre">everything</span></tt> / <tt class="docutils literal"><span class="pre">hosted_everything</span></tt>.</dd>
