True!  But even faster, per the "optimization" tricks in "The KORN Shell",
would be:

export SHELL=/bin/ksh

which can also be stated:

set -a
SHELL=/bin/ksh

In the first example, other env vars can be set in the same "line."  In the
second example, the "set -a" (where "a" = allexport) means all vars set will
be automatically exported.

I strongly urge people to acquire a copy of "The KORN Shell" which is THE
definitive reference work regarding ksh (besides which it contains numerous
"tricks" and addresses efficiency issues).
