title: How to check json file is having a particular string
body: <pre><code>&quot;Myapplication&quot;: {        
          &quot;RequestTimeoutAfterXHours&quot;: 24,
          &quot;Settings&quot;: [
              {
                  &quot;Name&quot;: &quot;app2
                  &quot;MetadataUrl&quot;: &quot;{app2}/mine/.known/configuration&quot;,
                  &quot;ValidateIssuer&quot;: false
              }
          ]
      },
  &quot;application&quot;: {
      &quot;app2&quot;: {
        &quot;MetadataUrl&quot;: &quot;{app2}/mine/.known/configuration&quot;,
        &quot;ValidateIssuer&quot;: false
      }
    }
  </code></pre>
