Various shells let you do this. I use bash, the Bourne Again SHell, which
is free from the FSF. It's pretty damn good. I especially like the
EMACS-style file completion facility, and it runs sh scripts.

Not too much effort to port and debug - there were a few bugs, but it
was only release 1.02. Could do with some more work to improve the
signal handling on SysV, which can be flaky, particularly in scripts.

Other shells which have some sort of line-editing or history mechanism
include csh, ksh, ksh-i and wash.
