<h1>Create</h1>
<p>Yaml files can be created using the 'new' command. This works in the same way as the write command, but you don't pass in an existing Yaml file.</p>
2017-12-19 00:59:27 +00:00
<pre><code>yq n &lt;path&gt; &lt;new value&gt;
2017-04-13 05:36:59 +00:00
</code></pre>
<h3 id="creating-a-simple-yaml-file">Creating a simple yaml file<a class="headerlink" href="#creating-a-simple-yaml-file" title="Permanent link">&para;</a></h3>
2017-12-19 00:59:27 +00:00
<pre><code class="bash">yq n b.c cat
2017-04-13 05:36:59 +00:00
</code></pre>
<p>will output:</p>
<pre><code class="yaml">b:
c: cat
</code></pre>
<h3 id="creating-using-a-create-script">Creating using a create script<a class="headerlink" href="#creating-using-a-create-script" title="Permanent link">&para;</a></h3>
2017-04-13 05:36:59 +00:00
<p>Create scripts follow the same format as the update scripts.</p>
<p>Given a script create_instructions.yaml of:</p>
<pre><code class="yaml">b.c: 3
b.e[0].name: Howdy Partner
</code></pre>
<p>then</p>
2017-12-19 00:59:27 +00:00
<pre><code class="bash">yq n -s create_instructions.yaml
2017-04-13 05:36:59 +00:00
</code></pre>
<p>will output:</p>
<pre><code class="yaml">b:
c: 3
e:
- name: Howdy Partner
</code></pre>
<p>You can also pipe the instructions in:</p>
2017-12-19 00:59:27 +00:00
<pre><code class="bash">cat create_instructions.yaml | yq n -s -
2017-04-13 05:36:59 +00:00
</code></pre>
<h3 id="keys-with-dots">Keys with dots<a class="headerlink" href="#keys-with-dots" title="Permanent link">&para;</a></h3>
<p>When specifying a key that has a dot use key lookup indicator.</p>
<pre><code class="yaml">b:
foo.bar: 7
</code></pre>
<pre><code class="bash">yaml r sample.yaml 'b[foo.bar]'
</code></pre>
<pre><code class="bash">yaml w sample.yaml 'b[foo.bar]' 9
</code></pre>
<p>Any valid yaml key can be specified as part of a key lookup.</p>
<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>
