I just recently purchased a used Tandy 6000 and had two questions:
- The XEN*X manual says if the 'shutdown' command to warn other
users of the impending shutdown in XX minutes and the computer
will then shut itself down. The manual also notes the use of
sync; /etc/haltsys
to shut the system down. If I use 'shutdown', do I need to use
other command?
- The version of XEN*X I am using is 3.02. Can anyone recommend a
XEN*X or UN*X reference book for this version? The 'currect'
Microsoft books seem geared twards XEN*X 3.2 on PC's.
Thanks!

"sync; haltsys" is only recomended for emergencies. Shutdown (optionally) warns the users of impending doom, then disables logins, kills all the running processes that it can; then unmounting any mounted filesystems. Finally, it runs /etc/haltsys. The new shutdown (3.2's) has a `-q' option, which means "bring it down NOW, don't warn the users". It's fairly quick now. | - The version of XEN*X I am using is 3.02.

Not right off the bat, no. The UNIX that this XENIX is based off of is UNIX System III, though, and as such is closer to UNIX V than v7 or Berkeley. Hope that helps. The other thing I should mention is that you get a complete manual set if you purchase the 3.0 development system. There is only an upgrade kit for 3.2 (comes with diskettes and replacement manual pages). I'll bet there are a few Radio Shack stores that would be more than happy to get rid of any they might have. You may have to call around, though. uh,clem over the cube wall here also recommends the following book (I'd forgotten about this one, it's pretty good): A User Guide to the UNIX(tm) System ISBN 0-931988-71-3 OSBORNE/McGraw-Hill 630 Bancroft Way Berkeley, CA 94710 The cover says the book is "System III compatible", and it pretty much is. You might be able to find this book at a larger bookstore or at a technical bookstore. Have fun, and if you have any further questions, send me mail! ---- IV (aka John Elliott IV) Domain: iv@hal6000.Tandy.COM Tandy Systems Software UUCP: ...!texbell!letni!hal6000!iv 900 Two Tandy Center or: ...!decvax!microsoft!trsvax!hal6000!iv Fort Worth, TX 76102 Phone: 817/390-2701; 9:30am-6:00pm CST, M-F
