Reply-To: [EMAIL PROTECTED]
I am looking for the command that will help me compare two directory
structures.
I just did a file copy to an NFS drive and I want to make sure that I
got everything.
I used
cp -axv /dev /mnt/vol00
cp -axv /bin /mnt/vol00
cp -axv/usr /mnt/vol00
etc . . .
Doing some sampling, it appears that everything copied okay.
What I am looking for is the equivalent to this
dos command: dir *.* /s
i.e. I am looking for file counts and directory counts as well as
total sizes.
thanks in advance,
charles

I need help to login from linux to a NT RAS server.
I keep getting E-691 PAP authroization fail.
The RAS server expect the domain\user, but my linux box seems just

I set the domain in the DNS tab, but does not seem any help.
Any info is appreciated.

These solutions won't tell where they found the match.
Markus' solution can be enhanced to do that:
find . -name '*.txt' -exec grep "Hello World" {} \; -print

If nobody comes up with a better solution (this works at least under the
bash):
cd olddir
find . -type f -print | while read path
do
newpath=3D`echo $path | sed "s/olddir/newdir/"`
# you can now compare the old and new files
if [ ! -e $newpath ]
then echo $newpath does not exist
elif cmp -s $path $newpath
then :
else files $path $newpath differ
fi
done
This reads back all files over the net. As an alternative you can do
cd $olddir
find . -exec cksum {} \; > /tmp/cksums
then move the file cksums over to the new machine and run this script
cd newdir
while read line
do set $line
n=3D`cksum $file`
if [ "$line" !=3D "$n" ]
then echo $line '<->' $n
fi
done < /tmp/cksums

The command is "stty intr ^C" (You can type it as a caret (^) followed
by an upper case C, stty will understand this)
I'm not sure if you can put it into any of the rc scripts, but as it's
very short, why not type it?

There's more to rpm and friends than just injecting files here and there
into a directory tree, checking dependencies for one and the most
important thing: documenting what's installed.
Rather than doing a "find / -name command -print" (and going to lunch)
to see if a command is installed ("Rats, did I install the help files
with them?" followed by another "find" and another lunch break),
searching the rpm database to decide whether the package is installed
and if it's the right version is a lot easier.
Also, removing a package is a lot easier: No leftovers (err ... not from
lunch), no broken dependencies, documented removal.

This is exactly what rpm and friends are doing.
Besides, replacing the "splattering of files all over the /usr tree"
(BTW that should have been "/opt tree") by ... what? ... splattering
files all over the file system, doesn't appeal to me.

Compared to one \WINDOWS\SYSTEM directory, the scheme with /usr, /opt,
/var, /etc, /lib sure sounds a little more structured.

No, I'd rather have a few centralized locations where I (and my shell)
can look for commands. It saves a lot of directory accesses and speeds
up command execution considerably. Symbolic links have been mentioned
already.

What I usually do to verify my copy is
"du" the original and the copy filesystem.
If you want to check every single file it
might be a good idea to write the two dumps
into two temporary files and "diff" these.

If "man read" doesn't show anything at all, you have not installed the
man pages.
If it shows some "read(1)" or "read(n)" man page, then you're led into
the wrong manual section. Try "man 2 read" instead (the read() function
is considered a system call which is covered in section 2 of the
manual).

Subject: c++ in linux kernel (c++ exceptions)
Date: Mon, 11 Dec 2000 09:50:26 +0100
Hello,
this is related to one of the last thread "c++ in kernel and linker
problems".
Over teh weekend I studied the libstdc++/gcc sources. There are some
startup
code for calling dtors (__do_global_Xtors_aux) and for stack unwinding
on exceptions (__XXregister_frame_info) at gcc.
Well, from this side here I could use g++ and exceptions inside kernel
but,
there are the terminate function from glibc, which is needed by
libstdc++.
This would be one of the bigger problem. How can I terminate a module?
The best solution would be the call all destructors and "auto
cleanup_module"
for this imo. Or are here better solutions (maybee I'm wrong ?).
The next is the .init section of user space programms. Is there for
kernel space
as well? What did I have forgotten ????
At last, may solution would be to write a wrapper for init_module() and
cleanup_module which does the above task. Writing a wrapper fo
new/delete
isn't a problem (it's interesting to see, that libstdc++ is using
malloc/free intern).
Porting code the other problem, but without exceptions, porting is very
heavy.
Some ideas ?
Thanks Olaf

However, TWAIN is not really a driver, but a way to access a device
from an application. Windows/DOS didn't have a standard way to do
that because of the DOS legacy of letting device drivers do whatever
they wanted (before TWAIN). Unix (and therefore Linux) already have
a standard way to access ALL devices. Applications for Unix use
this standard universally. This standard is that each device has
a special filename, and this name is opened like a file, and calls
to read, write, and ioctl will manipulate the device driver.
It doesn't make sense to make a TWAIN driver for Linux because what
TWAIN does is neither needed, nor even workable. It could be possible
to make a library that emulated the TWAIN driver. But if you're going
to port a scanner application to Linux from Windows, you have more to
worry about than accessing the scanner.
Whatever else TWAIN supports, the same issues apply, because Unix
already has a standard way to support accessing devices.

Subject: help creating procfiles - struct proc_dir_entry
Date: Mon, 11 Dec 2000 09:34:45 GMT
Hello....
I use the kernels 2.2.16 and 2.2.14.
For debugging purposes (driver modules) i want to put some files to
procfs. I want to read and write these files. Ive looked into
<linux/proc_fs.h> and found there are several different ways to do that
(so many fields in struct proc_dir_entry). So i wrote some modules (as
explained in ldd and lkmpg) that do it via fops and inode and also a
module that use the "get_info" field for this. I find 2 other fields in
struct proc_dir_entry "read_proc" and "write_proc". I played around
with this and it also works.
But im unsure with the parameters "*page" and "*eof" in "read_proc".
What are they for ? Im also interested whats the preferred (best) way
for creating procfiles. What are the differences (apart from coding
affort) between the ways "(*get_info)" -- "(*read_proc);(*write_proc)" -
- " implementation using inode and file ops" ? There are some sources
in the kernel that implement both for one proc file: "get_info" and
also a function for reading the procfile in their fops. What is this
for ?
Would be very nice if somebody can explain that vast number of things
to me.
Thanks in advance ...Michael Palme
