I fail to see what all this cli wizardry achieves that
du -h /dir/you/are/looking/at
wouldn't do.
du -hs will give you just a human-readable summary of the directory you give
it.
To count just a specific set of files:
du -hc public_html/*.html
will count each html file in your webpages and show a grand total.
Simple, and easy to remember. And a quick 'man du' reminds you of the options.

Subject: A kernel build question WRT SHMMAX
Date: Sun, 02 Jul 2000 08:36:58 -0500
<I previously posted this on comp.os.linux.setup and received no
response. Trying here...>
I've compiled a new 2.2.14 kernel with a couple of changes to shared
memory and semiphore parameters. In particular, I've changed the value
of SHMMAX in /usr/src/linux/include/asm/shmparam.h from the default
value of 0x2000000 to 0x8000000 (this because I have 256M of RAM). I've
also changed the values of SEMMSL and SEMOPM in
/usr/src/linux/include/linux/sem.h.
Prior to installing the new kernel, ipcs -l shows SHMMAX as 16M, as well
as the default values for SEMMSL and SEMOPM.
After booting with the new kernel, ipcs -l shows SHMMAX still as16M but
shows the new values for SEMMSL and SEMOPM.
Have I missed something in the compile process?

That's doing it the hard way. Use mcopy and you won't need to mount

Huh?
All CDs are made with the ISO9660 filesystem, unless they're made with the
UDF filesystem (this is not recommended as of yet.) Joliet and Rock Ridge
are extensions to the ISO9660 filesystem that allow for long filenames,
symbolic links, UID/GIDs, and more than 8 levels of subdirectories.
Linux can see and use plain ISO9660 CDs, CDs with Rock Ridge extensions,
and CDs with Joliet extensions. Lose9x will not recognize Rock Ridge
extensions, but it will be able to use the CD as a plain ISO9660 CD.

Read the documentation for Apache, paying particular attention to the
UserDir option in the configuration file. If that's set as "html", then
anyone requesting http://blah.com/~me will get directed to /home/me/html/
.
For the chroot behavior you desire, put the usernames in the
file /etc/ftpchroot (check docs on your FTP daemon; this is correct for
in.ftpd but may not be for others.)
You'll want to turn on disk quotas too.

You could try and make a 'user menu' or 'favorites menu' (depending on
which version of gnome you are using), by right clicking on the panel.
These function in a similar manner to the main gnome 'foot' menu.To edit
these menu entries, (as root) choose Settings::Menu Editor, or type
'gmenu' in a terminal.
It seems that drawer menus will always be large. Perhaps this will be
customisable in a later version.

Hi Ryan,
I'm having a very tough time getting Linux (Caldera eDesktop)
installed on a K7V Athlon 700MHz System. Maybe I've got a
problem with the memory as well - how did you figure that
out ? Is there any test software you used ? Or did you
just try another module ????
It would be great news if changing the RAM module would
enable me to finally install linux....
Thanks,

Let's quantify this. Suppose you've got a web server that serves up
mostly text -- no big graphics, no big sound file, etc. The average file
size this server dishes out is 10KB. At 90Kbps, it takes about 1 second
to serve that file. Even assuming 60 hits an hour, therefore, this web
server consumes only about 1.7% of the upstream bandwidth, reducing
effective speed from 90Kbps to 88Kbps.

Correct. Also, if you DON'T run a mail server, presumably you'll be
getting the mail via POP, IMAP, or something similar. The same bandwidth
gets chewed up either way. If you run Fetchmail to get POP or IMAP mail,
there's not much difference, but if you manually retrieve POP or IMAP
mail, there'd be an effective REDUCTION in speed, because you'd be
retrieving mail when you're sitting at the computer trying to do
something, vs. letting it come in when you might be off doing something
else. At DSL speeds and typical mail message sizes, this wouldn't be a
big effect, though. It might be important if you regularly receive
very large messages, though.

1) This is a residential account we're talking about. Restrictions on
the type of server are far better than forbidding servers altogether.
I believe Speakeasy's concern is that porn sites chew up so much
bandwidth that they're not willing to let a residential customer run
one.
2) There are situations when an ISP should get involved in the
customer's online behavior and site content. For instance, if a
customer spams (even from another ISP) and advertises a web address,
IMHO the ISP is justified in closing down that web site (assuming the
ISP has an appropriately tough anti-spam policy, of course).

You can register a domain name and associate it with an ADSL account,
too, *IF* you've got a static IP address. That's not a characteristic
that's unique to SDSL among the DSL variants, although it's probably
more common among SDSL setups than ADSL. For that matter, using a
dynamip IP address and a dynamic DNS service (like http://www.tzo.com,
http://www.dynip.com, or http://www.dyndns.org), you could do it by
using CNAME and MX records. For instance, if you get a subdomain called
foo.bar.com from a dynamic DNS provider, and create a web and mail
server at www.foo.bar.com, you could purchase a domain name like
example.com, and set up www in example.com to point to www.foo.bar.com
via a CNAME DNS entry. Similarly, you'd set up an MX in example.com to
point to www.foo.bar.com. This adds an extra layer to the name
resolution process, and it's got all the flaws of the dynamic DNS
services, but it SHOULD work. (Disclaimer: I've never actually tried
it, so I'm talking theory here.)

I wouldn't answer the orginal poster's question!
He didn't ask how to emulate du. He wanted to know how to cut
out fields from multi-line output and do arithmetic on them.
The ls just happened to be a convenient example which provided
that type of output.
However, an awk script is probably far too complex for someone
so new to shell scripting as to ask that question. He should
instead be looking at the "cut" and "read" shell commands.

Thanks that did it.
I found that Media Player produced a time out "Waiting for device
1". I remembered that the OSS instructions recommend using dsp1 as
sound device and had some instructions on linking that to dsp. Which I
did - killing sounds except for CD. Unlinking /dev/dsp from /dev/dsp1
fixed it. Game sounds (in Rocks and Diamonds e.g.) are horrible
still. And some of the example wav files sound completely chopped
up. I seem to remember that to be something to do how the wav is
recorded though?

I usually use tar:

If you want to go the filesystem route, you have to
