Use the "find" command to locate files with 0 size, and use the
-exec option to invoke "ls -l":
find . -size 0 -maxdepth 1 -exec ls -l '{}' \;
There are no doubt some pretty easy ways to feed the output of
"ls -l" to awk and accomplish the same thing. Perl would also
be easy...
Perhaps worth noting is that "find" can also select files that
are greater than or smaller than a given size. Read the "find"
man page for more ideas!

All processes are first notified that the system is going
down by the signal SIGTERM. This gives programs like vi(1)
the time to save the file being edited, mail and news
processing programs a chance to exit cleanly, etc.
The -t option allows adjustment of the time between when SIGTERM
is sent and when the next runlevel is actually invoked. Unless
your system is running a process that takes significant time to
properly terminate, there seems to be no benefit to using the -t
option.

The "+2" and the "now" options are conflicting. Without trying
it or looking at the source code it's hard to say which is
used, but probably the last one on the command line.

The -t option specifies seconds, hence it would be hard to
notice the difference between this and the above command.

Reading the man pages is more practical than actually invoking
shutdown!

Subject: Problems mounting mixed mode CDs
Date: Sat, 25 Nov 2000 21:28:56 +0100
Hi,
trying to "reduce" some old LPs to CD format, I ran into a problem that
seems to be so trivial that I couldn't find the answer on the net :-) I
recorded the LP to .wav files (one for each track), scanned the covers
and reduced them to CD size with GIMP. Because the audio data of an LP
usually does not exceed about 450M, I decided to use the remaining space
to burn the GIMP files of the cover to the CD also.
First attempt:
ISO-Image is track 1, audio tracks are tracks 2 and up.
Result: I can mount the ISO image, but the CD player tries to play track
1 as audio data, which gives some minutes of silence until the first
audio track starts. I can skip the data track, but I'd like it better if
the CD would start playing immediately after I put it into the CD
player. So I tried
Second attempt:
Burned the iso image as the last track of the CD after the audio tracks.
Result: CD starts playing immediately, but I could not find a way to
mount the data track.
cdrecord -toc gives
first: 1 last 6
track: 1 lba: 0 ( 0) 00:02:00 adr: 1 control: 0 mode:
-1
track: 2 lba: 16427 ( 65708) 03:41:02 adr: 1 control: 0 mode:
-1
track: 3 lba: 72529 ( 290116) 16:09:04 adr: 1 control: 0 mode:
-1
track: 4 lba: 112956 ( 451824) 25:08:06 adr: 1 control: 0 mode:
-1
track: 5 lba: 137273 ( 549092) 30:32:23 adr: 1 control: 0 mode:
-1
track: 6 lba: 165378 ( 661512) 36:47:03 adr: 1 control: 4 mode: 1
track:lout lba: 209197 ( 836788) 46:31:22 adr: 1 control: 4 mode:
-1
so I tried
mount -t iso9660 -o root=165378 /dev/scd0 /cdrom
and
mount -t iso9660 -o root=836788 /dev/scd0 /cdrom
but that results in the following error message:
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
or too many mounted file systems
It seems to me that the root=xxx options is ignored at all because I can
mount an usual data CD with any value of xxx.
mount -V shows
mount: mount-2.9t
Kernel is 2.2.16.
What's wrong? Any help or a pointer to TFM would be nice.

Wish!!
Unless I'm totally blind, there is only a NICI client for Linux which is not
what is looked for here. I believe that it is possible to get ncpfs working
with IP. If you can't figure it out from the (unfortunately limited)
documentation, I suggest that you get in touch with Petr Vandrovec who
maintains it. His email address is also in the documentation. He is very
helpful indeed.

I downloaded the rpm of FLTK, and it installed smoothly.
However, when I try to install the rpm of POSE, I get the following
error.
error: failed dependencies:
libstdc++-libc6.1-2.so.3 is needed by pose-3.0a4-1mdk
So, I installed glibc-2.2-5.i386.rpm.
I still get the same error when I try to install the POSE rpm.
How can I resolve the dependencies error?

What are the errors you are getting?
Did you isntall all dependcies as mentioned in the article?
Please post the errors so we can tackle the problem together.

If "make" fails, all succeeding commands are bound to fail as well.

That's a source-rpm, but you build a normal rpm from this one.
Oh, and here's a normal rpm:

Maybe you need to refer back to the original question.
1. how do you know which one is the process you just started?
2. how does it uniquely identify the process you just started?
3. when you assign this to a shell variable, how do you ensure that
anything you then do with that shell variable only works on the
one process you intend to handle?

Date: Sat, 25 Nov 2000 23:04:18 +0100
Hi,
I seem to have lost my superblock on my /dev/hdb1 disk, which I used as
usual Linux system. The thing is : At boot, it somehow does not find the "/"
root folder, and tells me to run e2fsck with alternate superblock. However,
when I does this, it tells me my disk had been unproperly unmounted and
"repairs" it. If I redo the thing, I get the same.
However, a plain "fsck" will show a clean /dev/hdb1 !
And, more : I can mount and navigate my disk from the other Linux on
/dev/hda !
I have tried to run FIPS : it can write the table, but for some reason, it
complains that it can't re-read it !
Heeeeeelp !

As another poster suggested, the find command is more appropriate for
the apparent purpuse of you script.
But I suspect you want to learn shell programming, in that case:
1. The first line can be simplified to
for file in *
BTW, try:
echo *
it makes a poor man's ls in rare situations where ls is not
available. 8-)
2. Surround the $file with double quotes like this: "$file"
3. The ! (also called ``bang'') is a special char in most shells and
many other commands and needs to be escaped if running this from
the command line or if ``source''-ing it. You don't have to do
this inside a script, but it won't hurt either.
man source
4. ls is often aliased or it is defined as a shell function, so you
end up invoking ls with options that you did not intend to be used.
In shell scripts it is usually best to use full path names for
commands, e.g. /bin/ls
Putting all this together:
for file in *; do
if [ \! -s "$file" ]; then
/bin/ls "$file"
fi
done
Using LOGICAL-AND you could also write it like this:
for file in *; do test \! -s "$file" && /bin/ls "$file"; done
test and [ are synonymous. They are available as separate commands.
But most often you would use the shell built-in versions which is the
default if you don't specify the full path.
Note that /usr/bin/[ is usually a hardlink or symlink to /usr/bin/test.
man test

Bill,
Thanks for the quick reply.
I've been using apsfilter, which in turn uses ghostscript printing to
standard output, to print text files. I found that when trying to print
ascii files without a filter, the accents (for foreign words) wouldn't
print properly. In all ways except with "J" at the beginning of a line, the
files now print just the way I want them to.
There are lines in my /etc/printcap file that contain different parameters
for each filter.

I noticed that my server admin email addres was set to
"root@localhost". I went into linuxconf to change it.
When I did that i did the usual activate the changes option upon
exiting linuxconf.
I then tried to access a page from another computer and then got the
message:
Forbiden
You dont have permission to access /index.html on this server.
I then restarted linuxconf to look see if anything looked screwy to
me. It didn't.
When I went to exit it propted me to activate the changes. The thing
is that I didn't make any. I selected make the changes anyway.
Just to see what happened I started linuxconf and quit right away. It
prompted me to activate the changes again and I selected it. I went
through this several times.
What is wrong?

It's their first issue.
Make sure you have all the development libraries nessisary, and then compile
POSE. Don't trust binaries too much.
When you do the make, do it with:
make | tee errors.txt
If you get an error with make, post to us the last 20 or so lines and we can

I installed vnc and it works great for this purpose.
The x-server and X-client can be "broken" between windows and unix but vnc does
the network break after the X-server. So the X-server and X-client work on the
unix box and are matched by default. Vnc just takes the graphical part and
renders it on the windows machine.
Also Vnc is freeware and X-servers seem to want money for one that
works(compatible) well on windows.
