I think it's by intention. It was just on the Bash mailing list, that even inside $PATH the ~ will be expanded (and it's not easy to get it inside, as it's expanded already at the time of assignment usually), and whether this behavior should be or not.


What other applications do to allow it (like the queuing system GridEngine), is to have a pseudo variable $HOME in the configuration. It's not the one from the shell per se, but they look it up in case they encounter it in the configuration.

But I'm not sure whether, it would be good to have it in `ssh`. Why not setting up two target machines in the config file?
