title: How to append lots of variables to one variable with a simple command
body: <p>I want to stick all the variables into one variable</p>
  
  <pre><code>A=('blah')
  AA=('blah2')
  AAA=('blah3')
  AAB=('blah4')
  AAC=('blah5')
  #^^lets pretend theres 100 more of these ^^
  #Variable composition
  #after AAA, is AAB then AAC then AAD etc etc, does that 100 times
  </code></pre>
  
  <p>I want them all placed into this MASTER variable</p>
  
  <pre><code>#MASTER=${A}${AA}${AAA} (&lt;-- insert AAB, AAC and 100 more variables here)
  </code></pre>
  
  <p>I obviously don't want to type 100 variables in this expression because there's probably an easier way to do this. Plus I'm gonna be doing more of these therefore I need it automated.</p>
  
  <p>I'm relatively new to sed, awk, is there a way to append those 100 variables into the master variable?</p>
  
  <p>For this specific purpose I DO NOT want an array.</p>
