You can use "echo $0", although it may not tell the real story... for
instance, there's a "pdksh" which is often installed as "ksh", and isn't
a genuine Korn shell. (And I believe some systems install "tcsh" as
"csh".
For Korn shell, you can tell if it's genuine if you:
set -o vi
<Esc> <Ctrl-V>
you should see:
Version M 1993-12-28 n+
or something like that. (Which would identify it at "ksh93" instead of
the venerable but still common "ksh88".)
