If you have some file that has been saved on a (Win)do(w)s host you may notice that all lines end with ^M.
To fix this, you can use the tool dos2unix. If however this tool is not at your disposal, you may have a problem. If vim is available, you do not have a problem:
The trick is to delete all occurances of ^M with this line:
:%s/ctrl-v ctrl-m//g
This will look like:
:%s/^M//g
Just save the file and you're done.
