It works. However, each exec_command opens a new session. Within the
first session, you do the cd command, and in the second session, the
process in whose context the cd was executed has already terminated.
You get a new process, and that starts out with the default directory
again.
You need to open a remote shell, and send commands to its command
line; AFAICT, you can't use exec_command for that.
