`xmessage connected' will be executed even though ssh hasn't exit(0)'d
yet.
bash: syntax error near unexpected token `&&'
You probably meant this:
$ { ssh user@host &; } && xmessage connected
Still, you would always be running "xmessage connected" even in the
case of "ssh user@host" failing, which is not what he wants.
Sorry yeah, I didn't clarify enough - meant to say that it wasn't
actually a valid shell script, I was just saying what it would be sort
of like.
But obviously it can't be done in shell, even with your {} / () subshell
stuff, since we can't tell if ssh has connected until it exits (without
a decent bit of hackery anyway).
