<p>If a key or value has leading dashes, yq won't know that you are passing a value as opposed to a flag (and you will get a 'bad flag syntax' error).</p>

<h3 id="keys-with-dots">Keys with dots<a class="headerlink" href="#keys-with-dots" title="Permanent link">¶</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>
|
||||
<h3 id="keys-and-values-with-leading-dashes">Keys (and values) with leading dashes<a class="headerlink" href="#keys-and-values-with-leading-dashes" title="Permanent link">¶</a></h3>
|
||||
<p>If a key or value has leading dashes, yq won't know that you are passing a value as opposed to a flag (and you will get a 'bad flag syntax' error).</p>
|
||||
<p>To fix that, you will need to tell it to stop processing flags by adding '--' after the last flag like so:</p>
|
||||
<pre><code class="bash">yq n -t -- --key --value
|
||||
</code></pre>
|
||||
|
||||
<p>Will result in</p>
|
||||
<pre><code>--key: --value
|
||||
</code></pre>

<p>To fix that, you will need to tell it to stop processing flags by adding '--' after the last flag like so:</p>
