<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 syntax:</p>

</pre></div>

<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 value as specified by <tt class="docutils literal"><span class="pre">chef_repo_path</span></tt> in client.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>
<dt><tt class="docutils literal"><span class="pre">--[no-]recurse</span></tt></dt>
<dd>Use <tt class="docutils literal"><span class="pre">--recurse</span></tt> to list dependencies recursively. This option can only be used when <tt class="docutils literal"><span class="pre">--tree</span></tt> is set to <tt class="docutils literal"><span class="pre">true</span></tt>. Default: <tt class="docutils literal"><span class="pre">--no-recurse</span></tt>.</dd>
<dt><tt class="docutils literal"><span class="pre">--remote</span></tt></dt>
<dd>Indicates that dependencies will be determined from objects located on the Chef server instead of the local chef-repo. Default: <tt class="docutils literal"><span class="pre">false</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.

<dt><tt class="docutils literal"><span class="pre">--tree</span></tt></dt>

<h2>Examples<a class="headerlink" href="#examples" title="Permalink to this headline">¶</a></h2>
<p>The following examples show how to use this Knife subcommand:</p>
<p><strong>Find dependencies for a node</strong></p>
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>knife deps nodes/node_name.json
</pre></div>
</div>
<p><strong>Find dependencies for a role</strong></p>
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>knife deps roles/role_name.json
</pre></div>
</div>
<p><strong>Find dependencies for a cookbook</strong></p>
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>knife deps cookbooks/cookbook_name.json
</pre></div>
</div>
<p><strong>Find dependencies for an environment</strong></p>
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>knife deps environments/environment_name.json
</pre></div>
</div>
<p><strong>Find dependencies for a combination of nodes, roles, and so on</strong></p>
<p>To find the dependencies for a combination of nodes, cookbooks, roles, and/or environments:</p>
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>knife deps cookbooks/git.json cookbooks/github.json roles/base.json environments/desert.json nodes/mynode.json
</pre></div>
</div>
<p><strong>Use a wildcard</strong></p>
<p>A wildcard can be used to return all of the child nodes. For example, all of the environments:</p>
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>knife deps environments/*.json
</pre></div>
</div>
<p><strong>Return as tree</strong></p>
<p>Use the <tt class="docutils literal"><span class="pre">--tree</span></tt> option to view the results with structure:</p>
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>knife deps roles/webserver.json
</pre></div>
</div>
<p>to return something like:</p>
<div class="highlight-bash"><div class="highlight"><pre>roles/webserver.json
roles/base.json
cookbooks/github
cookbooks/git
cookbooks/users
cookbooks/apache2
</pre></div>
</div>
<p><strong>Pass knife deps output to knife upload</strong></p>
<p>The output of <strong>knife deps</strong> can be passed to <strong>knife upload</strong>:</p>
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>knife upload <span class="sb">`</span>knife deps nodes/*.json
</pre></div>
</div>
<p><strong>Pass knife deps output to knife xargs</strong></p>
<p>The output of <strong>knife deps</strong> can be passed to <strong>knife xargs</strong>:</p>
<div class="highlight-bash"><div class="highlight"><pre><span class="nv">$ </span>knife deps nodes/*.json | xargs knife upload
</pre></div>
