Line ending issue DOS > Linux > Java -

I'm having trouble with 160,000 lines of files, this file was generated through an xlsx file exported in There is a .txt extension but I am afraid that it has been exported as a DOS-like file, at the end of each line it has a dos line break, I am using a parser written in Java, running on the Ubuntu environment I have been, and when I run a parser (I Because I can not use source code of part of a jar), I get number format expexation, hope for a number, my line ends in such a way:

  4449   
 but the parser sees it as  
  Input String: "4449 & amp; #xd;" & Lt;   
 Do you have the solution? Again, I can not reach the parser myself, I have to edit the file on my "Ubuntu Machine" and end the line.   
 
 
 Try using the  dos2unix  command on that file it's line terminator Should fix
