title: Bash delete everything before the first blank on every line
body: <p>I have file of logs that all start with the timestamp, followed by the log level and then the message and I want a script that gets rid of the timestamp.</p>
  
  <p>That is, I want a script that for every line of a file would turn:</p>
  
  <pre><code>21:22:34.571 DEBUG - some message
  </code></pre>
  
  <p>into</p>
  
  <pre><code>DEBUG - some message
  </code></pre>
  
  <p>I haven't used bash much so any advice would be appreciated.</p>
