<h2>Description<a class="headerlink" href="#description" title="Link to this heading">¶</a></h2>
<p><code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">length</span></code> reports the length of each string argument in characters. Exit status: 0 if at least one non-empty <em>STRING</em> was given, or 1 otherwise.</p>
<p>With <strong>-V</strong> or <strong>--visible</strong>, it uses the visible width of the arguments. That means it will discount escape sequences fish knows about, account for $fish_emoji_width and $fish_ambiguous_width. It will also count each line (separated by <code class="docutils literal notranslate"><span class="pre">\n</span></code>) on its own, and with a carriage return (<code class="docutils literal notranslate"><span class="pre">\r</span></code>) count only the widest stretch on a line. The intent is to measure the number of columns the <em>STRING</em> would occupy in the current terminal.</p>
