title: Issue is repo creation script
body: <p>I'm facing issue for below script. Syntax error: invalid arithmetic operator (error token is “.repo”). Intention of the script is to check whether MariaDB.repo is present or not, if not then create an empty file withe same name. Kindly suggest where i'm getting wrong &amp; how to fix this.</p>
  
  <pre><code>MDB=$(find '/etc/yum.repos.d/' -maxdepth 1 -name  "MariaDB.repo")
  
  if [[ $"MDB" -eq "MariaDB.repo" ]]
  then
      echo "Repo already exists"
  else
      touch /etc/yum.repos.d/MariaDB.repo
  fi
  </code></pre>
