Dump is an interactive program. As such, it will complain about
problems and demand help from an operator. It is not well suited to
unattended backups. (There is no such thing as a cheap, reliable,
unattended 9 track tape backup system, incidentally---there are too
many things that can go wrong [consider the missing EOT marker and the
tape that winds off the source reel, e.g.]. A fancy system might have
robotic recovery, but that is far out of reach of most small
installations.)
Some versions of dump (4.3BSD included) will note that /dev/tty is not
available, and will abort relatively cleanly; this could be used as
part of a semi-automatic system that simply bombs out if anything goes
wrong. This only works if dump is run without a controlling terminal,
but that should be true for cron jobs.

Just another BSD/SysV difference, which explains the differing opinions
(apparently the hyphen in "non-existent" is another):
% rm nosuch
rm: nosuch non-existent
----------
Of course, according to my Webster's 9th Collegiate, "nonexistent" is not
hyphenated. so, in this case, BSD is correct.

If you want everyone on your system to have their KSH time out after, say,
5 minutes, set TMOUT in the /etc/profile to 5*60 seconds or 300. This
would be the line you'd add to /etc/profile:
TMOUT=300; export TMOUT; readonly TMOUT
With the readonly on there, the users cannot change or unset it in their
login shell.

I would like to have a listing that shows only directory names (without
showing subdirectories) with the date of the last change to any non-directory
file contained in that tree. Comparing this to a similar listing of
archive files would show which ones need to be updated. The date of
a directory itself is pretty useless for this purpose, since compressing
files, compiling, deleting *.o files, etc. will affect the dir date
even though no real changes have happened. I have almost resorted
to running zoo on all the directories where I am not actively working
just to get this effect...
Can it be done with any of the usual tools? Hmm.. might be a good job
for perl when the version with filename globbing is released.

[...details omitted....]
First off you do not say just what sort of network it is you are using.
Assuming it is ethernet I have a few suggestions. If you use something
like Desqview or DoubleDos on the Dos machine you should be able to
both run your dedicated application and a tcp/ip package concurrently.
You might consider looking into the KA9Q tcp package, it is limited but
is functional and public domain, it has support for ethernet (3com), point
to point async. or various packet radio setups (which I don't think would
be relevant here). The source and pc-dos objects are available on turnkey.
The source has a makefile for SysV and BSD as well. We have successfully
compiled and used it between an SCO Xenix system and DOS system using
point-to-point async.
What I would suggest as a scenario is this. You run one of the above-mentioned
so-called DOS multitasking packages, then with the KA9Q package running as
one task the system would accept ftp put's of data whenever you desired. On
the UNIX side you could have cron set up to check for data and then do an
automatic ftp to the DOS system whenever necessary. I suspect this would work
out nicely for you, as well as being very inexpensive. Send me some email if
you have further questions or need more detail.
turnkey has an anonymous uucp account if you wish to obtain the archive
mentioned. Login as nuucp, no password; ph# (714)662-7450 request the file:
/usr/spool/uucppublic/files
and you should be on your way. Let me know of your success.
Best of luck,

Keywords: bug, egrep, regular expressions, ed
To: info-unix at SEM.BRL.MIL
While hacking /usr/lib/calendar to get it to understand about "10-Jun-88"-
style dates, I found what I think is a bug in egrep. I generated the RE:
'(0*10)([ -]*)([Ju][Uu][Nn][^ ]* *)'
^^^^^
However, when I did 'egrep RE calendar' I got nothing. Just for yucks, I
changed '[ -]*' to '[- ]*' and PRESTO - it worked.
Now, the manual page for ed(1) sez: "The following one-character REs match a
single character: . . . 1.4 A non-empty string of characters enclosed in
square brackets ([]) is a one-character RE that matches any single character
in that string. . . . The minus (-) may be used to indicate a range of . . .
The - loses this special meaning if it occurs first . . . or last in the
string."
Seems to me that either the manual page is wrong or egrep doesn't work "as
advertised". Can anybody out there either confirm this or tell me what I'm
missing? Oh yes, I've tried this on both a Sun w/s (Sun-2 I think) running
Interleaf and the gods alone know what under that as well as System V.2 on
my NEC XL. Same results, of course.
