So I just had an issue where my shebang lines weren't parsing properly for a python script I was attempting to execute. A quick google revealed that it was probably because I wrote the scripts on windows and now I was trying to run them on Linux (so happy i finally made the switch btw. using the computer is fun again!). So i took the advice I found and tried to run :%s/^M/ (using C-v, C-m to insert the escape character), and it failed to find any matches. I tried the same command in vanilla vi and it worked.
Is there some setting I don't have configured properly? I would prefer to be able to do this sort of thing within neovim.
