I have Fedora Core 6 installed on my machine and would like to create a
multipart rar archive of a video file for Usenet posting. The video avi
file is about 700Mb so I would like rar to create 15Mb volumes that all
make one big archive like they do in the binary Usenet newsgroups.

I have done this many times with WinRAR but it ties up my machine and I
would rather just copy the file to the Linux box with samba, then create
the rar archive on the CLI because I have rar installed on my Fedora
machine but do not have a GUI interface for it. Once it is on the Linux
machine, I can then putty over to it and open a screen to do the work,
then check back on it later, or just open a term to do it on the machine
or exit gnome and do it. Either way works fine but I like to use screen
as then I can go back and reopen the screen session to check on it or
close it out when it is done from anywhere.

I have tried several times to accomplish this but nothing I have tried
works or does what I want for it to do. Yes I have "man rar" and I have
googled for examples but most of the google pages tell how to extract
files from rar, not how to create multipart rar archives. I can just run
rar at the CLI and get some very terse information but still cannot get
it to work. Here is the basic help I get when I run rar by itself:

Here is what happens when I try to do what I think will make the rar
archive, split into 15Mb chuncks as in:

GoodMovie.rar.rar
GoodMovie.rar.00
GoodMovie.rar.01
GoodMovie.rar.01
...etc.

Adding    Really Terrific Movie - Part 1.avi                           0%
User break
[ohmster@ohmster post]$

Well that for sure did not work, I did a Ctl-c to kill it.

Since I see no option to create an archive, I use the program "rar" with
command "a" to add files. Then I use the "-v" switch to tell it to create
chunks and follow it with the size I want "15000k" as in fifteen hundred
kilobyte chunks, meaning 15Mb. I then tell rar the name of the new
archive will be "GoodMovie.rar" and that it is to add everything in the
current directory to the new archive by using a wildcard, "*". In this
case, the only thing in the current directory is "Really Terrific Movie -
Part 1.avi".

[ohmster@ohmster post]$ ls -lh
total 702M
-rw-r--r-- 1 ohmster ohmster 701M May  6 12:44 Really Terrific Movie -
Part 1.avi
[ohmster@ohmster post]$

I have tried all kinds of variations on this, none of them just creates
the archive in 15Mb chunks the way I want, the way WinRAR does. In
WinRAR, I just right click the file, choose (rar icon) "add to
archive...", then WinRAR comes up and there is the filename with an rar
extension on it that you can change if you want and also a dropdown box
where you can choose a predetermined size such as "1,457.664 - 3.5" (For
a floppy disk I guess) or put your own like I do 15,000,000, then just
click the "OK" button and the process begins, easy as that. No mistakes,
works great.

...but this is Linux, and I want to do this in Linux, and I have to use
the command line with the right commands, switches, and parameters. Can
somebody please, please show me how to do this as I am pulling my hair
out with this one, cannot google for it (Since it is not free, not very
much information on how to use it other than getting files extracted.),
cannot get the gist of the man page or the rar help.

Take this file:
-rw-r--r-- 1 ohmster ohmster 701M May  6 12:44 Really Terrific Movie -
Part 1.avi

Create an rar file of it that is split into 15Mb chunks.

Someone please provide a working example. I am going nuts on this one.
Thank you.

for tar files is that splitting on 100MB
"tar czvf - source | split -d -b 100m -"

for rar files check "rar --help"

Thanks for the help EOS, but I cannot use tar as most Usenet binary
people do not have a Linux machine or even know what a tar file is. I
think that Winzip can open a tar file but that would really create
problems, I have to use rar.

What I posted was "rar --help", those are the commands and switches to
use with rar, I just cannot seem to get the results I want with it.  I am
sure that it is quite possible to do and that some Linux guru will easily
understand the help output that I posted and be able to come up with
working command line syntax, for me the answer that I seek appears to be
quite elusive.

Either somebody in here knows how to do it because they have already done
so or can try it on their machine to see if the syntax that they come up
with will work, that is, if some kind soul is interested and will try to
help. I have done that for other newbies and others in here have really
rolled up their sleeves and have helped me out too.

I think it was that fellow that makes the weekly FAQ and stats for the
newsgroup, Michael Heiming, helped me out a lot back in the days when
installing nvidia drivers was not so easy as it is now with the nvidia
installer that is available for Linux downloads. Back then, you had to
download and compile a kernel module and with Redhat and rpm files, there
were no kernel headers on the system and you really needed that to build
the nvidia kernel module. Mike had another Linux machine at his house
that had Redhat on it with an nvidia card so the figured out how to use
rpm to use ftp to download, extract, and install the kernel headers with
rpm and then how to build and install the drivers. It was no "walk in the
park" but he did it and did a bang up job of it, for sure. I bet that one
post of his has probably been googled for and helped out a great many
other beginner Linux enthusiasts all over the world. That is the great
thing about Usenet and google, once you make a post, it gets archived and
if someone else is in the same mess as you are in, they can google for
and find the help that they need.

I still get emails from others that have had similar problems to mine,
the latest one was cifs and making mount work with samba shares on
Fedora. I kept getting a memory error and with the help of Steven French,
the guy who wrote the cifs module for Linux, eventually figured out that
it was not Linux that was the problem, it was the XP machine with the
shares. I tried to mount shares from a different XP machine and it worked
so then with a little follow up and more googling, we tracked it down to
a registry addition to the un-mountable samba share XP machine, that
allowed my samba shares to be mounted, finally. I answer all such
requests for help because I have been there and have been stuck like that
too.

Anyway, I will keep plugging away and maybe someone here can help figure
it out, thanks for trying.

rar a -v15000k <good.movie.name>

This will create;
<good.movie.name>.part01.rar,
<good.movie.name>.part02.rar
<good.movie.name>.part03.rar
etc.

rar a -v15000k -vn <good.movie.name>

will create;
<good.movie.name>.rar
<good.movie.name>.r00
<good.movie.name>.r01
etc.

The individual files will be 14.6MB each, except the last, which will be
smaller. The command puts every file in the working directory into the
.rar files, so if you only want the movie rared, be sure it's the only
file in the working directory

Newbie, newbie, newbie.

Damn, I've wanted to do that to some regular for a long time. :D

See my other post. I just wanted to add;

rar t *part01.rar

will test the new .rar files for integrity. If the old style numbering is
used, .r00, .r01, the command is simply;

rar t *.rar

Have fun.  ;)

Have you looked at the included documenation?

Look for the part in the doc that corresponds with that.
There are examples.

The docfile is much more detailed than the man page.
It has everything you need.

$ locate rar.txt

You may come up with rar.txt.gz, but someone who's
been using Linux for as many years as you have should
certainly know how to read that.  (Actually someone
who's been using Linux for so many years shouldn't need
to be told to use locate, or to look in /usr/share/doc
but hey...

AFAIK, all win archive managers know how to use tar. WinZip, WinRar,
7zip, WinArj... can use tar because it's a very simple archive.

Thank you so much. For some reason, I really got a brain lock on this one

Agreed, but then I will get a string of follow-ups like "What the hell is a
tar file and what do I do with it?" type stuff. Will just do the rar thing
and let it be done. Tar for sure is a very good way to get things done
though.
