It will exit and restart bash, using the same process id.
I am not sure that it is possible to get the pathname for the
current process on all systems.
However for linux, and some other systems
/proc/$$/exe
is a symlink to the pathname of the current process so
ME=$(ls -l /proc/$$/exe)
ME=${ME#*-\> }
will give the pathname for ksh (the current process and
alias rr='echo "+++ Restarting $ME ..."; exec $ME'
will do the same as your rr alias.
