Since non-Cygwin executables don't understand ptys, they think they are dealing with a pipe and so they buffer their output. It's not specific to OpenSSH. You'd see the same issue running these programs under xterm or mintty. I personally wouldn't define anything about this particular issue as a "lost cause" but YMMV. Quite some time ago there was an attempt to smooth out this issue with a utility call ttyfier but it had it's issues and has pretty much disappeared. I don't know of any other aids out there, though that doesn't mean there isn't something . The only things I can suggest are that you make sure there's not some Cygwin utility that does what you want or that you write something that does. -- Larry _____________________________________________________________________ A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting annoying in email? -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
