Sometimes, the file created at windows may tag alone the trailing character at the end of every line, where user press enter. It may shows as ^M. It is very irritating! to clear it off is very easy in vim.
:%s/\s*\r*$//%s is global search, change effect on every lines, \s is space \s* is to search for one or more space or no space, \r* is one or more or none carry return, $ indicate \s*\r* must appear at the end of the line, // means nothing. So searching for trailing character which we don’t want and replace with nothing.
It can be written as
:%s#\s*\r*$##Donno vim? Learn it up, refers to this post. It is very to learn up, the requirement is you have to learn it and use it often.
