Feature requests for scp and ssh

[Simon Kissane]

Hi

Would it be possible to add an option to the scp command, so that if a
destination file already exists, rather than overwriting it, scp just
skips the destination file, prints a message to stderr and returns an
error (non-zero) exit? That would help me immensely.

Also, you might want to think about providing a way to execute a
series of ssh, scp and sftp commands through one authentication
session, so if using password authentication you don't need to keep on
re-keying the password. Maybe have some kind of background daemon,
which holds the session open once authenticated, and then the
ssh/scp/sftp clients connect to it to perform operations. (I know key
authentication would work here, but sometimes server admins aren't so
keen on key authentication, and would prefer you physically entering
your password.)

Cheers
