Ah, thanks for setting me straight. I've probably been told before, but I 
always forget. Maybe I'll finally remember this time. My only ksh experience 
is in fixing a few shell scripts and interacting with pdksh on OpenBSD; I grew 
up on tcsh and switched to bash once it finally got enough of my favorite tcsh

Being able to download the source for free isn't sufficient for everybody; the 
license terms are important too.... Since ksh's current license terms have 
been approved by FSF, OSI, and Debian, I don't see why it couldn't be included 
in Linux. (And a further search indicates that it is in Debian and Ubuntu.) 
But I'm sure it's too restrictive for the BSD people, who tend to hate any 
sort of copyleft license.

Or sudo apt-get install ksh, if you're into that sort of thing.
