By setting it to '-' (a single dash) you get the output sent to STDOUT instead of a file. </p> <p class="level0">The PEM format this scripts uses for output makes the result readily available for use by just about all OpenSSL or GnuTLS powered applications, such as curl and others. </p><a name="OPTIONS"></a><h2 class="nroffsh">Options</h2> <p class="level0">The following options are supported: </p> <p class="level0"><a name="-b"></a><span class="nroffip">-b</span> </p> <p class="level1">backup an existing version of <span Class="emphasis">output</span> </p> <p class="level0"><a name="-d"></a><span class="nroffip">-d [name]</span> </p> <p class="level1">specify which Mozilla tree to pull <span Class="emphasis">certdata.txt</span> from (or a custom URL).
