Public Domain version of the famous
Korn Shell named after its author :
Dave Korn.
Supposed to bring the same level of
functionality the original thing does, it is half the size of the
Linux bash which make it even more proper to fit on a
floppy-
distribution.
It is however closer from ksh-88 than ksh-93 about which Dave Korn claims it may replace
Perl.
