SUN OS

LINUX

SCO UNIX

FREE BSD

AIX

MINIX

XENIX

OFS

-----------

SVR4

Is my third favourit system.
Today, this is the most common unix system
for almost all existing computor types.


SOLARIS

Sun Microsystems famous Soaris :)
It's mostely based on SVR.
Comes with the Bash,KSH,CSH shells.

SUN OS

Is the console part of solaris

LINUX:

Linux is the best unix system (At least i think and i belive there are many
who shares my thoughts :).)
Linux is based on SVR4 and BSD.

It comes with Tom's C shell and the bourne shell. 

SCO UNIX:

Wants to be the unix system of the future.
It's the most common unix system on Intel what we call Personal crap(PC))
It is based on the Xenix system.
SCO Unix comes with 3 kind's of shells:

Based on the bourne shell.
was created in Berkeley university.
Shells:

Bourne shell/Tom's C shell/Korn Shell

FREE BSD:
