I have not been able to get scp(1) to download a file with a newline in its name. I know that scp(1) requires that remote filenames be escaped for the shell, but that leads to protocol errors. I am also unable to get sftp(1) to handle such files. It fails with an “unterminated quoted argument” error, no matter how I try to quote the newline. Furthermore, the SFTP CLI is not well-suited to scripted transfers, as it requires creating batch files. If sftp(1) could accept commands as command line arguments, or in a NUL-delimited batch file, that would be great. While special characters (such as newlines) in filenames are probably bad practice, I believe that tools like scp(1) and sftp(1) should be able to deal with them. At least the SFTP protocol is perfectly capable of handling newlines in filenames, as I can delete a file with a newline in its name using Nautilus over SFTP. In case it matters, the client is a Fedora 30 Linux system, and the server is running the latest OpenBSD snapshot. Sincerely, Demi
