Unfortunately, I only started saving my history somewhat recently.<p><pre><code>    $ cat ~&#x2F;var&#x2F;history&#x2F;bash.d&#x2F;* | wc -l
    464291

    $ for year in 201{2..5} ; do
          echo -n &quot;${year}: &quot;
          cat ~&#x2F;var&#x2F;history&#x2F;bash.d&#x2F;${year}* | wc -l
      done
    2012: 116285
    2013: 175525
    2014: 117928
    2015: 54553
</code></pre>
It&#x27;s not a complete history, as I filter several commands with HISTIGNORE.
