title: Stuck with the "binary operator expected" message
body: <p>Stuck with the "binary operator expected" message when I run this command :</p>
  
  <pre><code>for variable in "ebooks" "movies" "games" "softwares" "music" "series" "tvreplay"
  do
      if [ -d /in/recep/downloader_ftp*/${variable} ]
      then
          mv /in/recep/downloader_ftp*/${variable}/* /in/arch/${variable}/ 
      else
          echo "no files type ${variable}"
      fi
  done
  </code></pre>
  
  <p>I know this is because the command find 2 directories starting with the pattern "downloader_ftp*" in the recep directory, but I can't figure good way to do it.</p>
