^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~

i love ram\’s!
How can I reverse all the text in a file using vi editor command?
freakin awsome. thank a bunch.
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
How to add ^M (Ctrl+V+M) in one particular line in an input file using script? Is it possible to store ^M in a variable?
the simplest way is to use the command dos2unix

Use dos2unix command. i.e. to replace all DOS characters to Unix –
$ dos2unix file.c file.c
^M comes from MAC files.
Thanks a lot…!!
Spooled file from Oracle SQL contained ^M at the end of every line along with a carriage return. This tip removed them, which enhanced readability tremendously. Thanks!!!

Is there any way to transfer a file from windows to unix without getting ^M characters
to send from windows, copy it into notepad first, or use the ‘Paste As’ command, and select plain text. (I dont think you can ‘paste as’ directly into notepad)
thanks!
You can definitely see your enthusiasm within the article you write.
The arena hopes for even more passionate writers such as you who aren’t afraid to mention how they believe. All the time go after your heart.
of course lik your weeb site but you need to check tthe spelling on several of your posts.
Several of them are rife with spelling problems and I find it very troublesome to tell the
truth then again I’ll definitely come again again.
Thanks so much for sharing all with the awesome info! I am looking forward to checking out far more posts! dccfacefkdbg
