<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">shorten</span></code> truncates each <em>STRING</em> to the given visible width and adds an ellipsis to indicate it. “Visible width” means the width of all visible characters added together, excluding escape sequences and accounting for <span class="target" id="index-0"></span><a class="reference internal" href="../language.html#envvar-fish_emoji_width"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">fish_emoji_width</span></code></a> and <span class="target" id="index-1"></span><a class="reference internal" href="../language.html#envvar-fish_ambiguous_width"><code class="xref std std-envvar docutils literal notranslate"><span class="pre">fish_ambiguous_width</span></code></a>. It is the amount of columns in a terminal the <em>STRING</em> occupies.</p>
<p>The escape sequences reflect what fish knows about, and how it computes its output. Your terminal might support more escapes, or not support escape sequences that fish knows about.</p>
<p>If <strong>-m</strong> or <strong>--max</strong> is given, truncate at the given width. Otherwise, the lowest non-zero width of all input strings is used. A max of 0 means no shortening takes place, all STRINGs are printed as-is.</p>
<p>If <strong>-N</strong> or <strong>--no-newline</strong> is given, only the first line (or last line with <strong>--left</strong>) of each STRING is used, and an ellipsis is added if it was multiline. This only works for STRINGs being given as arguments, multiple lines given on stdin will be interpreted as separate STRINGs instead.</p>
<p>If <strong>-c</strong> or <strong>--char</strong> is given, add <em>CHAR</em> instead of an ellipsis. This can also be empty or more than one character.</p>
<p>If <strong>-l</strong> or <strong>--left</strong> is given, remove text from the left on instead, so this prints the longest <em>suffix</em> of the string that fits. With <strong>--no-newline</strong>, this will take from the last line instead of the first.</p>
<p>If <strong>-q</strong> or <strong>--quiet</strong> is given, <code class="docutils literal notranslate"><span class="pre">string</span> <span class="pre">shorten</span></code> only runs for the return value - if anything would be shortened, it returns 0, else 1.</p>
<p>The default ellipsis is <code class="docutils literal notranslate"><span class="pre">…</span></code>. If fish thinks your system is incapable because of your locale, it will use <code class="docutils literal notranslate"><span class="pre">...</span></code> instead.</p>
<p>The return value is 0 if any shortening occurred, 1 otherwise.</p>
