title: Check location of current chromedriver
body: <p>I upgraded my chromedriver from v.2.35 to v.2.42. I have just downloaded v.2.42 and added to global path</p>
  
  <pre><code>export PATH=$PATH:/usr/lib/chromedriver
  </code></pre>
  
  <p>But when I enter in terminal <code>chromedriver</code>, I get </p>
  
  <pre><code>Starting ChromeDriver 2.35.528139 (47ead77cb35ad2a9a83248b292151462a66cd881) on port 9515 Only local connections are allowed. 
  </code></pre>
  
  <p>I cannot find that version of the driver in filesystem.</p>
  
  <p>My question is <strong>how to find out location of this old chromedriver</strong>. </p>
  
  <p>Selenium Tests still work, but I don't know which chromedriver version they are using. <code>pip3</code> and <code>pip</code> do not contain chromedriver.</p>
  
  <p>I would like to find location of all chromedrivers on the system.</p>
