There are numerous version of Unix-based software. Popular older
varients are SunOS, HP-UX, and IRIX. Popular newer varients are Linux
and Macintosh OSX. There are also several interfaces such as CURSES
and X-windows.
The software in this directory is all Unix-based. However not all may
work on your particular flavor of Unix. You may have to modify the
source code before you compile.
As I no longer operate a Unix-based system, I am unable to confirm the
suitability of any of this software. Use at your own risk.
