I never heard about this '***' Unix, what is it?
|
| |
Here's a brief list of some well-known (commercial/PD) Unices.
Any comment and/or new submission welcomed.
| Unix Name |
Description |
| AIX |
IBM's Unix, based on SVR2 with varying
degrees of BSD extensions, for various hardwares. Proprietary
system admin (SMIT). Quite different from most Unices and among themselves.
AIX/ESA, runs native on S/370 and S/390 mainframes, based on OSF/1.
AIX was to have been base for OSF/1 until Mach was chosen instead.
|
| AOS (IBM) |
4.3BSD port to IBM PC RT (for educational institutes).
|
| A/UX |
Apple's Unix. SV with Berkeley enhancements, NFS, Mac GUI.
System 7 runs as guest of A/UX (opposite of MachTen).
X11R4, MacX, TCP/IP, NFS, NIS, RPC/XDR, various shells, UFS or S5FS.
Apple has decided to drop A/UX (will go for AIX now that
they're together with IBM on the PPC)
|
| BOS |
Bull's DPX/2 (680x0). SVR3 with BSD extensions (FFS, select, sockets),
symmetric MP, X11R3, job control, disk mirroring, C2 security,
DCE extensions. There's also BOS/X, and AIX-compatible Unix for Bull's PPC
workstations.
|
| 386BSD |
Jolitz's port of Net/2 software. Posix, 32-bit, still in alpha.
|
| Coherent |
By Mark Williams Company. For 80286. Unix clone compatible with
V7, some SVR2 (IPC). V4.0 is 32-bit. Mark Williams closed down early '95.
|
| DC/OSx |
Pyramid machine. SVR4
|
| DELL UNIX |
DELL Computer Corp. SVR4
|
| DomainOS |
By Apollo, now HP. Proprietary OS; layered on top is BSD4.3 and
SVR3 (a process can use either, neither or both). Development now
stopped, some features now in OSF/1 (and NT).
|
| DYNIX |
Sequent machines. 4.2BSD-based
|
| EP/IX |
Control Data Corp. For MIPS 2000/3000/6000/4000; based on
RISC/OS 4 and 5, POSIX-ABI-compliant. SVR3, SVR4 and BSD modes.
|
| FreeBSD |
386bsd 0.1 with the patchkit applied, and many updated
utilities
|
| HP-UX |
From HP. BSD based, for HP-9000 CISC (300/400) and RISC (800/700),
shared libs, includes CDE
|
| IRIX |
From SGI. SVR3.2, much BSD. Version 5.x
is based on SVR4.
|
| Linux |
(i386/i486/i586/i686/ia64/alpha/sparc)
Unix under GPL (not from FSF, though).
Available with sources. POSIX compliant w/ SysV and
BSD extensions. Being ported to Alpha/AXP and
PowerPC (ports for 680x0 Amigas and Ataris already
exist; a port is also being done to the MIPS/4000).
|
| NetBSD 0.8 |
is actually 386bsd in a new suit. Ported to [34]86, MIPS,
Amiga, Sun, Mac.
|
| NeXTSTEP |
Intel Pentium and 86486, Hewlett-Packard PA-RISC, NeXT 68040,
BSD4.3 over Mach kernel, own GUI.
|
| OSF/1 |
DEC's port of OSF/1. Available on DEC' Alpha AXP (64-bit machine).
|
| Plan 9 |
From AT&T. Announced 1992, complete rewrite, not clear how close to
Unix it is. Key points: distributed, very small, various hardwares
(Sun, Mips, Next, SGI, generic hobbit, 680x0, PCs), C (not C++ as
rumors had it), new compiler, "8 1/2" window system (also very
small), 16-bit Unicode, CPU/file servers over high speed nets.
|
| SCO Unix |
80x86. SVR3.2
|
| Solaris |
From SUN. Available on Sparc, x86. With OpenWindows 3.0 (X11R4)
and OpenLook, DeskSet, ONC, NIS. Both a.out (BSD) and elf (SVR4)
formats. Kerberos support. Compilers unbundled!
Solaris is OpenStep compliant.
|
| SunOS |
From SUN. Available on 680x0, Sparc, i386, based
on 4.3BSD, includes much from System V. Main Sun
achievements: NFS, SunView, NeWS, OpenLook GUI standard,
OpenWindows (NeWS, X11, SunView!).
|
| Ultrix |
From DEC. Based on 4.2BSD with much of 4.3.
|
| UnixWare |
SVR4.2 |
