title: Split colon separated strings into array
body: <p>I want to split colon separated strings into an array. Each loop I have string like <code>ONE:TWO:THREE</code> now how can I split it into an array so I could access it like <code>string[1] //ONE, string[2] //TWO, string[3] //THREE</code>?</p>
  
  <p>This is the loop I use with the array content:</p>
  
  <pre><code>WORDS=(ONE:TWO:THREE FIVE:FOUR:THREE)
  for i in ${WORDS[@]} ; do
     [..]
  done
  </code></pre>
