How to run the. sh file in Cygwin?

The following is the contents of the auto.sh file that was originally run under Linux and is now running under Windows Server. Installed the Cygwin,

#!/bin/sh
#
#Script to Export
#
While:;
Do

php-d session.save_path=/dev/null-f/www/test.php >/dev/null
Sleep 3
Done

Run times wrong

-bash-4.1$./auto.sh
./auto.sh:line 10:syntax error near unexpected tokens ' done '
./auto.sh:line: ' Done '

What is the reason? Did I not install the Cygwin without installing the shell library or why?
When select packages to install
Choose Shells Bash: and bash-completion: What is the reason, willing to use a friend pointing, grateful!

The same problem, seek to solve

Because MS-DOS and windows are carriage return + newline to represent line breaks, so under Linux with Vim to see the code written in the VC under Windows, the "^m" symbol after the end of the line, indicating the character.
Now, you use Vim-b to open your file. You'll find that each row has ^m, so we can replace it with a global replacement.
