This doesn't seem to work in tcsh. When I try putting things like 1;31 in
my prompt, it just prints that string.
Thanks, though.

You may be confusing two different types of shared memory.
If you run top or free then they will report a value for
"shared memory" which is essentially the amount of memory
used by code in shared libraries. This reported value is
not a limit, but is a reflection on the type of processes
you are running and how much use they make of shared libraries.
If you are running a gui (e.g. gnome or kde) then the 43 meg
you mentioned is about right.
The other sort of shared memory is explicitly allocated and
used by programs. Unless you are getting error messages
from processes which cannot allocate enough of this shared
memory then you don't need to worry about it.

I have a HP netserver E60 with and Adaptec aic-7895 controler conected
to a HP 9.1 gig drive. I have tried to install RH 7.0. I get through
the whole install. Everything looks good. When I reboot after the
install, I get a list of L L L L L L L's going down my monitor. I know
that this means that LILO did not run all the way through. My problem
seems to be with RedHat 7.0, because if I install 6.2, it works
fine..Any ideas? Also, If I boot from the floppy, I can access my

It all depends on what desktop environment you're running, I think.
Although I'm reasonably confident that you can play around with the
settings in GNOME or KDE, whichever you're running (I think other GUIs
allow for this too), to use Alt-Tab to switch between applications. I'm
running GNOME right now, and I can tell you that in the Sawfish control
center, the "Shortcuts" option lets you define "M-Tab" to "Cycle
windows". I'm not sure how it's done in KDE, but if you're running
gnumeric, then you're probably running Gnome, so it's okay. Hope that
helps.

All the books I have go into some detail on how to set up and manage groups and
some of them go into some detail on the groups you'll find already set up on a
Linux system, but none of them give any hints on group management strategy.
Since the whole raison d'etre of groups in Unix is both to allow and to
restrict users to available system resources (and thus to maintain system
security) then the only answer to your question is another question: What do
you and your users intend to do with your Linux system?
I recommend that you start off by listing your users, the activities in which
they take part, and the resources needed by those activities. Then decide
whether to logically divide your users into groups according to the activities
or according to the resources, or, in some cases, both.
You will probably create some groups in order to manage one of the most
important resources on your syste: access to files and directories. This is
likely to be task-oriented (e.g. the accounts directory). Other groups might be
created in order to restrict access to certain hardware.
Hopefully others will come up with pointers to other sources of information,
and you might want to say more about the type of system you're using:
networking, office, personal, and so on, but in the end, it may be that only
you can decide on the best strategy.

I cannot coment on the HP or Plextor models but I have been using a Sony
cd writer (not sure of model, its at home and I'm not) )with both RedHat 6.0 and 6.2.
I have recently gone up to 7.0 but have not yet got around to trying it.
To get it going initially I simply followed the CD-writing howto and everything worked
fine. Rather than using any of the fancy frontends I simply use cdrecord
