title: Perl - remove first word in a string with regexps
body: <p>I'm new to both Perl and reg-ex's, and I'm trying to remove the first word in a string (or the first word in a line in a text file) , along with any whitespace that follows it. </p>
  
  <p>For example, if my string is <code>'one two abd123words'</code>, I want to remove <code>'one '</code>.  </p>
  
  <p>The code I was trying is: <code>$line =~/(\S)$/i</code>;<br>
  but this only gives me the last word.<br>
  If it makes any difference, the word i'm trying to remove is an input, and stored as $arg. </p>
