title: Commenting in a Bash script inside a multiline command
body: <p>How can I comment on each line of the following lines from a script?</p>
  
  <pre><code>cat ${MYSQLDUMP} | \
  sed '1d' | \
  tr ",;" "\n" | \
  sed -e 's/[asbi]:[0-9]*[:]*//g' -e '/^[{}]/d' -e 's/""//g' -e '/^"{/d' | \
  sed -n -e '/^"/p' -e '/^print_value$/,/^option_id$/p' | \
  sed -e '/^option_id/d' -e '/^print_value/d' -e 's/^"\(.*\)"$/\1/' | \
  tr "\n" "," | \
  sed -e 's/,\([0-9]*-[0-9]*-[0-9]*\)/\n\1/g' -e 's/,$//' | \
  sed -e 's/^/"/g' -e 's/$/"/g' -e 's/,/","/g' &gt;&gt; ${CSV}
  </code></pre>
  
  <p>If I try and add a comment like:</p>
  
  <pre><code>cat ${MYSQLDUMP} | \ # Output MYSQLDUMP File
  </code></pre>
  
  <p>I get:</p>
  
  <pre><code>#: not found
  </code></pre>
  
  <p>Is it possible to comment here?</p>
