No you have it the wrong way round. When you do an FTP transfer in ASCII mode it alters the line endings as appropriate, when in binary mode it doesn't. The ^M you are seeing is part of the Windows line-ending that is not understodd by systems that have Unix line-endings. The Windows line-ending is two characters, whereas the Unix line-ending is one. /J\	[reply]

Because line endings are different on Unix (and Linux) and DOS (and Windows). And they don't get translated in binary transfer mode.

Here's how it should work as I understand it: For ASCII mode, your line endings will be translated if possible. From UNIX to Windows, ^M (carriage return) characters are added. From Windows to UNIX they are removed, I believe. For binary mode, none of that translation is done. So for true text files, often you really want to use ascii mode. However, for just about anything else, you really want binary. You can really pull you hair out if you transfer a linux executable through a windows box back to linux if you use ASCII in one of the transfers. Bottom line: Think carefully, and be consistent! ---- My mission: To boldy split infinitives that have never been split before!	[reply]

if iam using binary it is adding . No, it is not adding them, it is leaving them in. In ascii mode, it removes them.	[reply]

In the quest for a utility to convert between *nix and DOS newlines on a regular basis, I have found flip: Newline conversion between Unix, Macintosh and MS-DOS ASCII files to be useful. It not only converts between DOS and Unix file formats, but also includes a handy `-t` command-line switch to tell you which format a given file uses. HTH, planetscape	[reply] [d/l]
