Can someone enlighten me as to what "munch" does for C++ and/or
for Concurrent C? I know it performs some sort of manipulations
on the object file but that's all I know. It also seems to add
a lot to compile time and I want to know if I can do without it.
I'm actually specifically interested in Concurrent C, but since
it uses nearly the same parser as C++, I gather that "munch" is
doing the same thing for both. Thanks for any information.
My apologies if this is a naive question.

Nope. Tom meant '$PWD' when he said it. The reason for the single quotes
is so that the shell where the definition is being made does not interpret
$PWD. If it did, the current working directory of _that_shell_ would
_always_ display. By quoting it, four characters ($, P, W, and D) are
exported and not interpreted by ksh _until_displayed_. I don't think sh-
does any interpretation of displayed variables in this manner, which is
why it doesn't work this way using sh-.
If you use back-quotes, as in above, you end up trying to execute a
directory.

Subject: Return from exit?

Keywords: curses exit signal
To: info-unix at sem.brl.mil
I have a small monitoring program which uses curses to update it's display
every 15 seconds. It has been in use and worked fine for a couple of years
with one exception: It appears that sometimes it returns from an exit!
SIGINT is set to be handled by this routine:
void quit()
{
signalson(NO); /* Leave us alone while we cleanup */
close(sysfd);
clear();
refresh();
endwin();
detachutil(); /* Log us out of shared memory */
puts("watch: terminated");
exit(0);
}
signalson(flag) /* Enable/disable sig handling routines */
int flag;
{
int i;
static int lastflag=YES;
if(flag==YES) {
signal(SIGINT,quit);
signal(SIGTERM,quit);
} else {
signal(SIGINT,SIG_IGN);
signal(SIGTERM,SIG_IGN);
}
i=lastflag;
lastflag=flag;
return(i);
}
When the interrupt key is sent to the process sometimes the screen will clear,
the exit message will be printed, and then a few seconds later the screen is
refreshed with the latest statistics. After that happens the interrupt key is
ignored and we must use SIGQUIT to kill the process.
Can anybody suggest why this might be happening?

The file was 118583 bytes. Does anybody have any ideas on how to

A friend of mine wants a csh alias that will print all lines in

just print the history.
He asked me and I suggested the following csh alias:
alias h ' \
if ( "X\!*" == "X" ) then \
history \
else \
history | grep \!* \

For some reason, this does not work. Can some kind soul explain why

The line

will set
hr to the current hour,
min to the current minute, and
sec to the current second.

Yes, but it's a stable development environment because AT&T
specifies what backward compatibility they'll provide in new
versions. This may be carried a bit too far, to the extent
that they're reluctant to fix misfeatures for fear of breaking
customers' work-arounds.
Any developer who's happy with the old functionality can
ship products for the newer version of the OS without having
to port to it.

I do cross development between Unix, VMS, and MSDOS; and I have
a few opinions on the subject. I consider Unix to be a superior
*development* environment, but VMS to be a superior *production*
environment. The variety of tools and power of the Shell make Unix
an ideal choice for technical types and programmers. The
sophistication of VMS, combined with its excellent documentation
and reliability make it the clear winner in production.

I don't know how to do it in csh, but the method that works for (k)sh is:
#! /bin/sh
exec 3<&0 < /usr/local/lib/ctrsuns
while read test
do
echo $test
rsh $test -n "$1"
done
exec 0<&3 3<&-
This gives the error missing name for redirect. You might
be able to fool around with it and get it working...

You are right. Here are the modified (quicker) versions:
2) Only name of current dir:
alias cd 'cd \!*; set foo=$cwd; set prompt=$foo:t"% "'
3) Include name of machine in prompt
alias cd 'cd \!*; set prompt=$host":"$cwd"% "'
or alias cd 'cd \!*; set foo=$cwd; set prompt=$host":"$foo:t"% "'
----------
I don't think you need the extra variable foo. "set prompt=$cwd:t" works
just fine.

I have a question about driver close routine. Thanks in advance for any answer.
If a process exits or terminates before it closes a driver, does kernel close
the driver for that process ? In user process, several processes can open the
same driver. Are driver open and close routines executed as many time as process
calls it ? Does kernel control the close system call, so close is only executed
once (when last process closes it)? When system crash, does kernel close all
the opened file and driver or just leave them open ?

You don't want csh scripts, if you want to avoid problems. Use sh scripts:
i=0
exec 3< foo
while read bar <&3
do
i=`expr $i + 1`
echo "line $i: $bar"

Probably there's a cd command in your .cshrc.
Furthermore, try if your kernel recognizes `#!/bin/csh -f' on line 1.

I think you misunderstand what "when bsd and System V are merged" means.
It means that S5R4 will be picking up BSD stuff, not that S5 and BSD
will become one and the same thing. As far as I know, Berkeley isn't
going to convert to S5R4, so presumably a 32V licence should continue to
be sufficient.

Keywords: csh C shell UNIX programming arrays subscripts
To: info-unix at sem.brl.mil
OK, I'm learning, I'm getting better at this...
Yes, our .cshrc ended with 'cd', apparently to initiate the pretty
prompt via the cd alias. So if I change that to 'cd .' instead, we
get the pretty prompt without reverting to HOME in every subshell.
Now I would like to know if csh can be warped into array-like subscripting.
I am trying to write a table-driven menu in a csh script, so that I can
loop through cases instead of adding another explicit paragraph of case
code whenever we expand the menu. Here's the rough outline:
------------------------------------------------------------
#csh
# menu4
@ n = 0
@ n += 1; set entry$n = (EXIT EXIT)
@ n += 1; set entry$n = (ADDUSER ADD a new user account)
@ n += 1; set entry$n = (MODUSER MODIFY a user account)
@ n += 1; set entry$n = (DELUSER DELETE a user account)
@ n += 1; set entry$n = (SHOWUSER SHOW a user account)
@ n += 1; set entry$n = (ADDCLASS Add a new CLASS)
@ n += 1; set entry$n = (ADDGROUP Add a new GROUP)
@ n += 1; set entry$n = (DELGROUP CANCEL a group)
@ n += 1; set entry$n = (INSTRUCT INSTRUCTION)
#This, for specific case 3, works:
set command = $entry3[1]
set prompt = "${entry3[2-]}"
echo The command $command will $prompt
#This, for general case i, fails, with message 'Variable Syntax':
@ i = 1
while( $i <= $n )
set command = ${entry$i[1]}
set prompt = "${entry$i[2-]}"
echo The command $command will $prompt
@ i += 1
end
------------------------------------------
That's as close as I have been able to get in a couple days trying
without the Anderson book. I'd be happy to consider another approach,
but for some other reasons we're kinda bound to doing it in C-shell.
(I'd rather do it in awk, but our awk here can't import the arv command
line, so it's (snicker) awkward.)

I think this will do the trick:
alias hh 'history | grep "\!*"'
This works because 'grep ""' is not the same as 'grep'.
Your alias produces strange behavior. Neither the "if" or the "else"
condition is ever executed. I don't know why.

Because the shell built-in "read" runs in a subshell due to the pipeline.
You're setting the variables in a subshell, all right, but that isn't

that getting bounced screws things up on my machine for some
undetermined amount of time (say--to the next boot up)?
2. Is there another method of specifying the address of machine,
rather than the Arpanet address (i.e., machine.university.edu)?
In some of the site lists, the give a bunch of numbers with
periods (302.333.23.2349) that appear to be some kind of address.
What is this?
Thanks for your time and help!

The program as written doesn't double panic uPort V/AT 2.2.2 with 80287,

My question is, since Berkeley has been paying licsence fees to
AT&T for portions of their code, will AT&T pay Berkeley for
portions of their code included in SVR4? If not, then will AT&T
price SVR4 so that users are not paying for portions of code that
AT&T did not buy or develop?
Anyone from AT&T or Berkeley wish to comment?

I'm sure that AT&T's lawyers have made the necessary contractural
arrangements with all providers of software that AT&T will be
distributing. I'm also sure that they're not going to disclose
the details of any such arrangement just because you're curious
about it. The pricing for SVR4 has not yet been announced.
The implied accusation of theft that lies behind your questions
is, to the best of my knowledge (and I do have some inside
knowledge) unfounded and demands an apology.

Yes and no. Yes for opens, no for closes. All opens get to the driver.

You got it, but not to confuse anyone else: You meant to say,
"...so *the driver's* close is only executed once..."
The kernel does execute close logic for every close system call
(decrement the reference counter for example), it just doesn't call the
driver's close routine until the reference counter is zero.

No. The kernel leaves everything basically as is (except for syncing
the drives). This is probably vendor specific; I know only about
the NCR TOWER.

Oops. The question was does the kernel close the *driver* when a process
terminates? The answer is clear if you read the rest of my posting,
but just in case:
All the files opened by the process are closed. If the file that is
the device node for the driver is closed and the reference count is
zero (last close for the device), then... yes, the driver gets closed
when the process terminates. Otherwise no.

Welcome to csh! Generally it doesn't like foreach, while, etc. in aliases.
Solutions:
alias h 'set q=(\!*); eval h$#q'
alias h0 history
alias h1 '(history | sed -n -e \$q -e /"$q"/p)'
or
alias h 'if ("\!*" == "") set status=1 &&'\

history
or
alias h 'if (\!* == "") set status=1 &&'\
'history | sed -n -e \$q -e /\!*/p ||'\
history
The final version causes csh to complain if multiple arguments are given.
BTW, it's obvious why I used sed instead of grep.

RE: Slicing the date
I've gotten several replies, and I need to clarify something -
I have tried the '+' notation on the 'date' command to get it to format its
output. The OS running here (I believe 4.3BSD) does not accept that. Any
argument is assumed to be an attempt to *set* the date, not format it,
according to the man pages and actual use. I was moved (against my will)
from SysV to BSD, and this is something that I lost - I used to use the
date '+%H:%M:%S' format, and it doesn't work anymore. That's why I have to
slice the normal output.

Maybe expr will work? Again, it's going to look sort of hideous, but it should
work. For example, if date produces "Wed Mar 29 16:57:30 1989" then
NOW=`date`
PS1=`expr "$NOW" : '... ... \(..\)'`
would set PS1=29, the day of the month. This is Bourne shell, by the way, and
would also work in Kourne shell (-: but not C-shell. I assume anyone forcibly
removed from a System V environment at least has the good sense to avoid csh
like the plague.

As far as I know, AT&T is negotiating with Sun to merge SunOS features
into SVR4, not with Berkeley. What the financial arrangements between
AT&T and Sun are, I have no idea.
Does Sun pay Berkeley for using BSD code in SunOS? How about
all other vendors who are "BSD derivatives"? Isn't BSD code public
domain (that is, BSD code that is not derived from AT&T)? If so, why
should AT&T or Sun or anyone else have to pay for getting something
that's already in the public domain?
