You can view break lines using gedit editor   First  if you don t have installed   sudo apt-get install gedit   Now  install gedit plugins     sudo apt-get install gedit-plugins   and select Draw Spaces plugin  enter on Preferences  and chose Draw new lines      Using VSCode you can install Line endings extension   Sublime Text 3 has a plugin called RawLineEdit that will display line endings and allow the insertion of arbitrary line-ending type  shift   ctrl   p and start type the name of the plugin  and toggle to show line ending

VI shows newlines  LF character  code x0A  by showing the subsequent text on the next line   Use the -b switch for binary mode  Eg vi -b filename or vim -b filename --   It will then show CR characters  x0D   which are not normally used in Unix style files  as the characters  M

Just to clarify why  set list won t show CR s as  M without e   ff unix and why  set list has nothing to do with  M s   Internally when Vim reads a file into its buffer  it replaces all line-ending characters with its own representation  let s call it   s   To determine what characters should be removed  it firstly detects in what format line endings are stored in a file  If there are only CRLF   r n  or only CR   r  or only LF   n  line-ending characters  then the  fileformat  is set to dos  mac and unix respectively   When list option is set  Vim displays   character when the line break occurred no matter what fileformat option has been detected  It uses its own internal representation of line-breaks and that s what it displays   Now when you write buffer to the disc  Vim inserts line-ending characters according to what fileformat options has been detected  essentially converting all those internal   s with appropriate characters  If the fileformat happened to be unix then it will simply write  n in place of its internal line-break   The trick is to force Vim to read a dos encoded file as unix one  The net effect is that it will remove all  n s leaving  r s untouched and display them as  M s in your buffer  Setting  set list will additionally show internal line-endings as    After all  you see  M  in place of dos encoded line-breaks   Also notice that  set list has nothing to do with showing  M s  You can check it by yourself  make sure you have disabled list option first  by inserting single CR using CTRL-V followed by Enter in insert mode  After writing buffer to disc and opening it again you will see  M despite list option being set to 0   You can find more about file formats on http   vim wikia com wiki File format or by typing help  fileformat  in Vim

I suggest you to edit your  vimrc file  for running a list of commands  Edit your  vimrc file  like this    cat  gt  gt     vimrc  lt  lt EOF set ffs unix set encoding utf-8 set fileencoding utf-8 set listchars eol    set list EOF   When you re executing vim  the commands into  vimrc are executed  and you can see this example    My line with CRLF eol here  M

Try the following command    set binary  In VIM  this should do the same thing as using the  -b  command line option   If you put this in your startup  i e   vimrc  file  it will always be in place for you   On many  nix systems  there is a  dos2unix  or  unix2dos  command that can process the file and correct any suspected line ending issues   If there is no problem with the line endings  the files will not be changed
