<h3>SYNOPSIS<a class="headerlink" href="#synopsis" title="Link to this heading">¶</a></h3>
<p>varnishadm [-h] [-n ident] [-p] [-S secretfile] [-T [address]:port] [-t timeout] [command […]]</p>
</section>
<section id="description">
<h3>DESCRIPTION<a class="headerlink" href="#description" title="Link to this heading">¶</a></h3>
<p>The <cite>varnishadm</cite> utility establishes a CLI connection to varnishd either
using -n <em>name</em> or using the -T and -S arguments. If -n <em>name</em> is
given the location of the secret file and the address:port is looked
up in shared memory. If neither is given <cite>varnishadm</cite> will look for an
instance without a given name.</p>
<p>If a command is given, the command and arguments are sent over the CLI
connection and the result returned on stdout.</p>
<p>If no command argument is given <cite>varnishadm</cite> will pass commands and
replies between the CLI socket and stdin/stdout.</p>
</section>
<section id="options">
<h3>OPTIONS<a class="headerlink" href="#options" title="Link to this heading">¶</a></h3>
<dl class="option-list">
<dt><kbd><span class="option">-h</span></kbd></dt>

<dd><p>Connect to the instance of <cite>varnishd</cite> with this name.</p>
</dd>
<dt><kbd><span class="option">-p</span></kbd></dt>
<dd><p>Force <cite>pass</cite> mode and make the output follow the VCLI protocol.
This disables command-history/command-completion and makes it
easier for programs to parse the response(s).</p>
</dd>
<dt><kbd><span class="option">-S <var>secretfile</var></span></kbd></dt>
<dd><p>Specify the authentication secret file. This should be the same -S
argument as was given to <cite>varnishd</cite>. Only processes which can read
the contents of this file, will be able to authenticate the CLI connection.</p>
</dd>
<dt><kbd><span class="option">-T <var>&lt;address:port&gt;</var></span></kbd></dt>
<dd><p>Connect to the management interface at the specified address and port.</p>
</dd>
<dt><kbd><span class="option">-t <var>timeout</var></span></kbd></dt>
<dd><p>Wait no longer than this many seconds for an operation to finish.</p>
</dd>
</dl>
<p>The syntax and operation of the actual CLI interface is described in
the <a class="reference internal" href="varnish-cli.html#varnish-cli-7"><span class="std std-ref">varnish-cli</span></a> manual page. Parameters are described in
<a class="reference internal" href="varnishd.html#varnishd-1"><span class="std std-ref">varnishd</span></a> manual page.</p>
<p>Additionally, a summary of commands can be obtained by issuing the
<em>help</em> command, and a summary of parameters can be obtained by issuing
the <em>param.show</em> command.</p>

<section id="exit-status">
<h3>EXIT STATUS<a class="headerlink" href="#exit-status" title="Link to this heading">¶</a></h3>
<p>If a command is given, the exit status of the <cite>varnishadm</cite> utility is
zero if the command succeeded, and non-zero otherwise.</p>
