title: Append date to filename in linux
body: <p>I want add the date next to a filename ("somefile.txt"). For example: somefile_25-11-2009.txt or somefile_25Nov2009.txt or anything to that effect</p>
  
  <p>Maybe a script will do or some command in the terminal window. I'm using Linux(Ubuntu).</p>
  
  <p>Thanks in advance.</p>
  
  <p>oh i almost forgot to add that the script or command should update the filename to a new date everytime you want to save the file into a specific folder but still keeping the previous files. So there would be files like this in the folder eventually: filename_18Oct2009.txt , filename_9Nov2009.txt , filename_23Nov2009.txt</p>
