+Below is a file that I copied from Windows to a CentOS linux server, it dind't matter if I copied the file, or did a copy/paste, the issue still arose. After each line you can see a <color #ed1c24>^M</color> character, which is a Windows carriage return (Linux doesn't use Carriage returns, only line feeds, Windows uses both).
-vi -b filename
+\\
+\\
+When you edit the file in vi, you can't see these special characters, you have use another switch with vi to show them. Run vi using a <color #ed1c24>-b</color> switch.

+You can remove these special characters in Linux using a variety of methods, here are two.
+\\
+. In vi, just delete the ^M characters and save the file.
+. Install dos2unix (yum install dos2unix) and execute this on your file (dos2unix filename)
+       and it will remove them for you, handy if it is a big file.
