<h1>Merge</h1>
<p>Yaml files can be merged using the 'merge' command. Each additional file merged with the first file will
set values for any key not existing already or where the key has no value.</p>

<h3 id="to-stdout">To Stdout<a class="headerlink" href="#to-stdout" title="Permanent link">&para;</a></h3>

<p>then</p>
<pre><code class="bash">yq m data1.yaml data2.yaml

<p>will output:</p>
<pre><code class="yaml">a: simple
b: [3, 4]
c:
test: 2
other: true
d: false

<p>Notice that 'b' does not result in the merging of the values within an array. </p>
<h3 id="append-values-with-arrays">Append values with arrays<a class="headerlink" href="#append-values-with-arrays" title="Permanent link">&para;</a></h3>
<p>Given a data1.yaml file of:</p>
<pre><code class="yaml">a: simple

</code></pre>
<p>and data3.yaml file of:</p>
<pre><code class="yaml">a: something

<p>then</p>
<pre><code class="bash">yq m -a data1.yaml data3.yaml

<p>will output:</p>
<pre><code class="yaml">a: simple
b: [1, 2, 3, 4]
c:
test: 2
other: true
d: hi
</code></pre>
<p>Note that the 'b' array has concatenated the values from the second data file. Also note that other map keys are not overridden (field a).</p>
<p>Append cannot be used with overwrite, if both flags are given then append is ignored.</p>
