title: echo working in a very different way
body: <p>Here <code>PLUGIN=ABC</code></p>
  
  <pre><code>$ echo "{\"PluginName\": \"${PLUGIN}\""
  ""PluginName": "ABC
  $ echo "{\"PluginName\":${PLUGIN}\",\"Filename\":\"${VAR}\" , \"ErrorString\":"
  ","Filename":"ABC" , "ErrorString":eployerProps
  </code></pre>
  
  <p>However if I change above variable PLUGIN to any other string its working.</p>
  
  <pre><code>$ echo "{\"PluginName\":\"${PLUGINS}\",\"Filename\":\"${VAR}\" , \"ErrorString\":"
  {"PluginName":"ABC","Filename":"ABC" , "ErrorString":
  </code></pre>
  
  <p>Not able to understand whats the reason. This is bash 4 however on other server its working fine.</p>
