I want use %s/^M//g to delete the ^M in *.c files.
In vimrc file, I added
au BufRead *.c :%s/^M//g<cr>
But Vim give me a E488 error. If I use
au BufRead *.c :%s/^M//g (delete the <cr> from above)
It will be no error, but I need to press Enter to continue.
Anyone could give me a hint?
Thanks!

E488 is "Trailing characters"
^M is a real Enter code, I don't know how it will be handled. Try using
au BufRead *.c %s/\r//g
instead; or to delete ^M (carriage return) only if found at the end of a
line (just before a linefeed character), but also in other common C/C++
source files,
au BufRead *.c,*.h,*.cpp %s/\r$//
Note that if _all_ lines including the last end in CR+LF, Vim (with
'fileformats' [plural] set to the default) should detect it as Dos
format and in that case the latter substitute won't find anything to
replace -- so I think it would be prudent (in both cases) to add an e
flag at the end (see :help :s_flags )
Best regards,
Tony.
