title: sed one-liner to delete all digits 0-9 that happen after a period
body: <p>I have</p>
  
  <pre><code>sed -e '/^ *[0-9]\+ *$/d' &lt;oldtextfile &gt;newtextfile
  </code></pre>
  
  <p>...which I use on text I have copied and pasted from PDFs to remove page numbers. However, I also need to remove footnote numbers, so I need to modify the above <code>sed</code> one-liner to do that by deleting any digits that happen after a period, and unfortunately I have very little patience for <code>sed</code>. Can someone help me out?</p>
