I don't think you need that first exec.
You are wanting to empty that log file, I assume, and this will do it:
:> .bash.startup.log
What happens when you use exec, is that you replace the shell with that
program, so I guess you'd have to kill it by finding its PID and
doing a kill -9 PID.
kill -9 $$
Might do it.
(You might want to put that command in a file called .bash_logout to
run as the shell exited rather than started up.)
