title: Sed: file or directory not found
body: <p>I'm trying to use the sed command to replace text in a config file with the line</p>
  
  <pre><code>sed -e 's/pass/Awmusic12635/2w' -i config.yml
  </code></pre>
  
  <p>I have already cd to the directory to where the file is, but every time I run it I get the error</p>
  
  <pre><code>sed: couldn't open file : No such file or directory
  </code></pre>
  
  <p>What could be causing this?</p>
