title: wget - keep the files with same name
body: <p>I am downloading some files from database by using wget but some of the files in database named same. So, when I download 2 files with the same name, the files break. I wonder if there is a way to keep both files. For example I downloaded file named a.png and I download another different file but with the same name and change the name into a 2.png
  <br>
  Simply I just need something that recognize the file with the same name and gives different name to the 2nd, 3rd, 4th, ...</p>
  
  <p>thank you..</p>
