<h1 class="subsection">Comments</h1>  <p>In a non-interactive shell, or an interactive shell in which the <code>interactive_comments</code> option to the <code>shopt</code> builtin is enabled (see <a href="the-shopt-builtin">The Shopt Builtin</a>), a word beginning with ‘<samp>#</samp>’ causes that word and all remaining characters on that line to be ignored. An interactive shell without the <code>interactive_comments</code> option enabled does not allow comments. The <code>interactive_comments</code> option is on by default in interactive shells. See <a href="interactive-shells">Interactive Shells</a>, for a description of what makes a shell interactive. </p><div class="_attribution">
