I have an SMB connection to an Ubuntu Server 12.10 host that has shell scripts and config files I want to edit with a Windows 7 client using Notepad++. I am able to open the files and make changes, but as soon as I save them, with no changes to the character encoding, they become unreadable on the host.

How can I edit and save the files in Windows 7 so they can be read and executed in Ubuntu Server 12.10?

What does 'unreadable' mean? – terdon Jan 16 '13 at 15:18
@terdon It means the Tomcat server using the config files stops working. – Keyslinger Jan 16 '13 at 15:25
OK, see Jim's answer then. Or mine. – terdon Jan 16 '13 at 15:26

EDIT: You can enable Unix line termination in Notepad++ in Edit -> EOL Conversion -> Unix Format.

One of the most common problems with text file compatibility between Unix and Windows systems is that Windows' notion of line termination is CRLF (carriage-return + linefeed, ascii 13 and 10), while Unix uses just LF (10). This is probably getting you an error like ./ bad interpreter: /bin/sh^M: no such file or directory.

There's a utility called dos2unix that will convert any existing files for you, on the Ubuntu side:

apt-get install dos2unix

That modifies the file in-place to strip out the CRs.

As Jim said, the problem is probably line termination. You can fix this on the Linux server by running this command on your modified files:

sed -i 'N;s/\r\n/\n/g' file

Jim's response helped me, but I'll keep this in mind in case I ever find myself without access to either of the solutions he gave me. – Keyslinger Jan 16 '13 at 15:40
Just to clarify, he gave you one solution. The first command just installs the necessary program, you will only need to run it once. – terdon Jan 16 '13 at 15:44
