title: Split string into array in bash
body: <p>I am looking for a way to split a string in bash over a delimiter string, and place the parts in an array.</p>
  
  <p>Simple case:</p>
  
  <pre><code>#!/bin/bash
  b="aaaaa/bbbbb/ddd/ffffff"
  echo "simple string: $b"
  
  IFS='/' b_split=($b)
  echo ;
  echo "split"
  for i in ${b_split[@]}
  do
      echo "------ new part ------"
      echo "$i"
  done
  </code></pre>
  
  <p>Gives output </p>
  
  <pre><code>simple string: aaaaa/bbbbb/ddd/ffffff
  
  split
  ------ new part ------
  aaaaa
  ------ new part ------
  bbbbb
  ------ new part ------
  ddd
  ------ new part ------
  ffffff
  </code></pre>
  
  <p>More complex case:</p>
  
  <pre><code>#!/bin/bash
  c=$(echo "AA=A"; echo "B=BB"; echo "======="; echo "C==CC"; echo "DD=D"; echo "======="; echo "EEE"; echo "FF";)
  echo "more complex string"
  echo "$c";
  echo ;
  echo "split";
  
  IFS='=======' c_split=($c) ;#    &lt;----    LINE TO BE CHANGED 
  
  for i in ${c_split[@]}
  do
      echo "------ new part ------"
      echo "$i"
  done
  </code></pre>
  
  <p>Gives output:</p>
  
  <pre><code>more complex string
  AA=A
  B=BB
  =======
  C==CC
  DD=D
  =======
  EEE
  FF
  
  split
  ------ new part ------
  AA
  ------ new part ------
  A
  B
  ------ new part ------
  BB
  
  ------ new part ------
  
  ------ new part ------
  
  ------ new part ------
  
  ------ new part ------
  
  ------ new part ------
  
  ------ new part ------
  
  ------ new part ------
  
  C
  ------ new part ------
  
  ------ new part ------
  CC
  DD
  ------ new part ------
  D
  
  ------ new part ------
  
  ------ new part ------
  
  ------ new part ------
  
  ------ new part ------
  
  ------ new part ------
  
  ------ new part ------
  
  ------ new part ------
  
  EEE
  FF
  </code></pre>
  
  <p>I would like the second output to be like </p>
  
  <pre><code>------ new part ------
  AA=A
  B=BB
  ------ new part ------
  C==CC
  DD=D
  ------ new part ------
  EEE
  FF
  </code></pre>
  
  <p>I.e. to <strong>split</strong> the string on a <strong>sequence of characters</strong>, instead of one. How can I do this?</p>
  
  <p>I am looking for an answer that would only modify this line in the second script:</p>
  
  <pre><code>IFS='=======' c_split=($c) ;#    &lt;----    LINE TO BE CHANGED 
  </code></pre>
