I've got a script, named `s`, on a remote server that activates a virtual environment like this:

    source venv/bin/activate

When SSH-ed into the server, I'm able to activate the environment by

    . s

And I SSH into the server as following:

    ssh -t user@host "cd /path/to/dir ; /bin/bash"

In addition to changing the working directory to `/path/to/dir` it would be nice if I could activate the environment right away each time I log into the server. But no matter where I put `. s` into the the SSH command, using `-c` for `/bin/bash` or not, the session always ends immediately.
