Here's an example that should get you in the right direction:
awk 'BEGIN {
SQ = sprintf("%c", 39);
DQ = sprintf("%c", 34);
}
{
printf("%cHow is this?%c\n", DQ, DQ);
printf("%cAnd this?%c\n", SQ, SQ);
}

Try avoid using quotes, double-quotes will make life a lot easier. I use
the following:
BEGIN { q = 39; }
{
printf "this is a quote: %c\n", q;
}
this free you up to worry about what you want to do instead of quoting
problem. Just remember the decimal value for quote is 39, I did not start
using this method until I memorized its value (the most intuitive reaction
a programmer has at that point is to use "quote" mostly because he can
not remember the decimal value for quote and dont feel like look into the
ASCII table for it!)

4.3-tahoe does a pfind, but not for pgroups (negative values), only for
pids (positive values), and only when translating to TIOCSPGRP (more
below).

Actually, I am fairly sure that SunOS 3.x had the 4.2BSD bug where pid
and pgroup were reversed (between documentation and code). Whether that
has been fixed, I do not know. (The SunOS 4.x code is substantially
different, and I have not read it.)

(The following applies only to 4.3BSD and otherwise-unchanged derivatives
thereof.)
F_SETOWN on an inode translates into a TIOCSPGRP ioctl, so that whatever
checks are applied to TIOCSPGRP are applied to fcntl(ttyf, F_SETOWN).
The translation goes like this:
if (value > 0) { [value is a pid, not a pgroup]
struct proc *p = pfind(value);
if (p == 0)
return (ESRCH);
value = p->p_pgrp;
} else [value is a negated pgroup ID]
value = -value;
return (fioctl(fp, (int)TIOCSPGRP, (caddr_t)&value);
For a socket, it sets ((struct socket *)fp->f_data)->so_pgrp to the
given value. Tty pgroups are stored in tp->t_pgrp: a different place.

They are unnecessary. SIGIO is a completely benign signal. If a
process is not catching it, SIGIO is discarded. If a process *is*
catching it, that process is required to figure out why the SIGIO occurred
and whether it still has any reason to do anything about it, so extra
SIGIO signals merely reduce efficiency.

The hack/botch is the F_SETOWN, or rather the whole fcntl(2) syscall.
As i recall fcntl(2) was (needlessly?) instituted by the creators of
System V(anilla) and adopted by Berkeley as a compatability measure,
nothing that really couldn't be done by ioctl(2) but a new syscall
was created anyhow.
and don't forget the overlaying (reuse) of the VTIME and VEOT
members of the AT&G Unix tty system - switch modes from to/from
'cbreak' and you have surprises too. but then, i suppose it was
done by a graduate student... .5;-)

Those checks are inappropriate for the F_SETOWN. For example, POSIX
insists that the tty in question be your controlling tty. That's both
unecessary and unlikely for processes wanting SIGIO on a tty.

Permission checks are rarely "unnecessary", it's much more likely that
they're either missing or incorrect. In this case, they're missing.
Suppose I have process A and process B. A does a F_SETOWN on some
socket and then goes on, expecting a SIGIO at some later time. B comes
along, and also does a F_SETOWN on the same socket. A has been
robbed.
To head off a needless discussion: yes, I realize that if you do the
"right thing" everything is OK and there is no need for permission
checks. My claim is that the number of programmers who "do the right
thing" (sorry spike) are getting fewer and fewer.

You misunderstand. I wasn't suggesting making direct edits on the memory
image. On the contrary, you map it in read-only if you can. What I was
suggesting was that since most of the things you're doing to the file don't
involve modifying it, you might as well page it in from disk when you
need it, only coping it to writable memory when you want to modify it.
For example, suppose you want to do a search and replace. You fault in
all the pages from here to the replacement location, copy the block that
contains the replacement into two new blocks (using the block-splitting
method) and add the new text. The blocks you just read can be discarded
when needed by the memory manager, rather than having to be written out
to the paging area, saving considerable disk access. Only modified blocks
would need to be written.

rsh works with /bin/sh and ksh. You can either execute the rsh command
(SysV) or execute the shell with the -r flag. You simply set the PATH to
point to a directory containing only the things you want to allow, and
then (assuming a recent shell) set the PATH variable readonly. I usually
create a /usr/rbin directory and link stuff in from /bin and /usr/bin.
Ex:
PATH=/usr/rbin
readonly PATH; export PATH

Think of pure buffer gap and linked line as opposite ends of a
continuum. (Technically, linked character would be on the one end,
but I will ignore that case.) Pure buffer gap has one chunk, which is
the entire object. As you divide it into separate chunks (paged
buffer gap), the number increases and their size decreases.
Eventually, you get to a chunk size of one line and have linked line.
In may of the intermediate cases, whether you use an array or linked
list is an implementation detail.

Where did this "75K" figure come from? It wasn't mentioned by me. It
would be a very unusual constant to remain constant over a wide range
of architectures, speeds, memory sizes, and other performance-related
figures.
In particular, I have had no trouble editing multi-megabyte files in
GNU Emacs on a Sun 3/280 w/8 MBytes of memory.

I will give a general description of an algorithm that can accomplish
what you ask.
NOTE: I am doing this from the 'top of my head'. Some refinement may
be in order.
You will do a weighted comparision based on two factors:
a) The number of characters each string has in common
b) The number of matches the strings have in sequence
Let's take two arbitrary strings:
"This old man can't read" string alpha
"That silly man can't read" string beta
Notice that they are of different lengths. Also, there is an alignment
shift. The following algorithm _should_ properly handle this:
a) Count the number of occurences of each character in each string.
Compare the count of each character in alpha to that in beta in the
following way:
For each different character from alpha & beta:
Normalize the counts so that the greater is normalized to 1.
Multiply the two normalized values toghether.
Add this product to a running total.
Normalize this total by the the length of the longest string
Multiply that by weight w1 yeilding (we shall call it) yw1
b) Compare the two strings byte for byte as follows:
Start at the beginning of alpha & beta (let's use i and j as indexes)
initialize k to 0
Until we hit the end of either string:
if (alpha[i] == beta[j])
++k, ++i, ++j
else
we scan forward on beta to find a byte that matchess
our current location on alpha. If so, adjust j to index
it. If nothing was found, do vice-versa for alpha.
When the above loop is completed,
Normalize k against the size of the longest string
and multiply it by weight w2 yeilding (we shall call it) yw2.
return (yw1 + yw2) / (w1 + w2)
This should produce a good evaluation of how closely matched alpha
is to beta, taking into account mis-alignment. The value returned
will be between 0 and 1 inclusive. Weight w1 should be less than w2.
Perhaps w1 = w2 / 3. Experiment.
As I said, this is off the top of my head, so some refinement is in
order, as should be evident during the implementation/testing phase.
If anyone knows of a better way to accomplish this, let's hear it!

:This is quite true. However, a similar thing can be implemented in the
:Bourne shell using shell functions. There are however two caveats :
:
: 1. We cannot use the name of a built in shell command
: 2. We must recaculate the PS1 each time we do a cd.
:
:Firstly, becase we want the PS1 to be updated whenever we change
:directories, we cannot use the builtin 'cd' command, but something like it.
:We must also remember to use the new command, because using a cd will mean
:that the directory reflected in our PS1 will be incorrect.
:
:You can try this Bourne shell function :
:
: go()
: {
: if [ "$1" ] # if we got an argument
: then
: cd $1
: else # otherwise go home
: cd $HOME
: fi
: PS1=`pwd`"> " # change the PS1
: }
:
For what it's worth, here is how I implemented things (from
file /usr/acct/ME/bin/.functs which I invoke as . .functs in
my .profile)
#
# This file invokes function definitions
#
# ps3="`cat /etc/NODENAME`/`basename \`tty\``> " # set in .profile
pd() { RT=$PWD; cd $1; PWD=`pwd`; PS1="$PWD
${ps3}"; }
lpd() { pd $1; ls; }
rt() { pd $RT; }
pd (path directory) changes my directory and reflects the current
directory as the first line of my two line prompt. The second line
tells me what system I am on (I have access to several) and what
line (I also have a variety of ways to tie in - modem, direct line,
pass thru line, Token Ring). If I am in a sub shell, a /n is
appended to the line number to indicate depth, since I'm frequently
nested through some intermediary program or other.
I can toggle between two directories with the rt command, very
useful wehn transferring files (mv pattern $RT).
:Remember, shell functions are not passed to their subshells.
:
But are accessible by shell scripts called by current shell. If
you are lucky enough to have an NCR Tower (no flames please, they
are my employers) they have the delightful .shrc feature implemented
that gets invoked when you fork an interactive shell. Once I found
that gem (by accident - it's not documented) I was able to invoke
my function definitions on all shell levels.
I have lots of other shifty functions. vi (no args) for instance,
edits my last edited file rather than a file with no name. Very
useful when mucking with balky items like makefiles.
