Use bash. Or tcsh. They have history list support. You can even search
through
the history (CTRL-R with bash).

Something that I have been wondering about (but too lazy to
investigate): The real KSH has an 'r' command to repeat the last command, or
the nth previous command, much like ! in csh. You can also say 'r ls' to
repeat the last 'ls' command, etc. But it seems that bash doesn't
even though it is supposed to be a KSH clone.
What is the equivalent of 'r' or ! in bash ?

Thanks.

alias r='fc -e -'

That's how it's defined in ksh too - it just happens to be a default
alias.

Actually, if all you want is command editing, then the
supplied "Bourne" shell has enough ksh-isms to understand
set -o emacs

(Maybe it does vi mode too, but I don't know.)

If only it did file name completion...

(maybe it does? how?)

Indeed,

if you want better ksh capability, and also the best interactive
features, you should use zsh. (It also has the r command).

Definitely a key to remember (at work I've got an IRIX account set up
with bash and I always attempt to use ESC-p which is the same thing in
tcsh).

The zsh does -- in fact, it seems to have all the best of tcsh, ksh, and sh
(it's ksh based). In fact, it has >programmable< complete, etc. -- extreme
power shell.
