^M is DOS line break charater which shows up in unix files when uploaded from a windows file system in ascii format.
To remove this, open your file in vi editor and type
:%s/(ctrl-v)(ctrl-m)//g
and press Enter key.
Important!! – press (Ctrl-v) (Ctrl-m) combination to enter ^M character, dont use “^” and M.
If anything goes wrong exit with q!.
I learned this from here.

Very good!
I just encountered this problem and it is so annoying to replace each ^M one by one!
Thank the god here is the solution~

Your substitution command may catch more ^M then necessary. Your file may contain valid ^M in the middle of a line of code for example. Use the following command instead to remove only those at the very end of lines:
:%s/(ctrl-v)(ctrl-m)*$//g
In some flavors of vi (e.g. RedHat), vi does it for you with:
:set fileformat=unix
