title: Echo text directly after variable
body: <p>I have 2 variables named <code>$min</code> and <code>$sec</code>.</p>
  
  <p><code>If $min = 5</code> and <code>$sec = 15</code> I want to print this <code>"5m 15s"</code>, <code>echo "$min m $sec s";</code></p>
  
  <p>But that gives "5 m 15 s".  How do I get rid of the blank space?</p>
