BASH Syntax error near unexpected token ‘done’

Run cat -v file.sh.

You most likely have a carriage return or no-break space in your file. cat -v will show them as ^M and M-BM- or M- respectively. It will similarly show any other strange characters you might have gotten into your file.

Remove the Windows line breaks with

tr -d '\r' < file.sh > fixedfile.sh
