Write file list

Hi,
 
Is it possible that cdrecord would ever support writing a list of files, perhaps given in a text file or argument list, instead of a whole directory?
 
I'm writing some script to automate backups to DVD-R, and I have directories that are more than 4.3GB in size. This means I have to start moving files around to create a folder for each disc, which is slightly inconvenient.
 
Is there some reason this isn't a good idea?
 
P

You seem to missunderstand how CD/DVD writing works.

cdrecord writes filesystem images - not files or file lists.

What do you like to do?

Well, if not the files, at least their names, no?

What am I missing?

You create an ISO image, and that is written to disk.
In other words, mkisofs touches the files, cdrecord doesn't.

Please reply to the list...
The mkisofs -graft-points option in combination with -path-list would
probably be what you need.
One Perl script I used a long time ago for incremental backups was using
that just fine to only back up changed files.

I'm not sure where the problem is, but for this mailing list (and only for
this list, ever, in my fifteen-year experience of such things) certain
people seem to end up with their own address in the reply-to header. This
is... abnormal.

Hmm, flame-war alert...
This list actually handles it correctly.

Just use a better mail program, e.g., one that handles reply-to-list, if
you don't want to use reply-all.

Again, Harumph!!!!

Suggestion to list owner; add in the signature appended to each
posting the notice to "Reply All" to avoid this problem -- I've
been bit by it too many times as well.

mkisofs only reads them.

If you like, you may tell mkisofs which original file to put under which name
into the iso image. There is no need to rename of copy the original files.

You either have a broken mail program or you don't use it correctly.

Use 'R' (Reply all)....

Using Reply all is what the nettiquette rules suggest, so why repeating it?

This is a problem of your local MTA. I get only one copy as both mails have the
same message ID.
 
BTW: please do not send personal mails only.

Can I have a hint, or is this a guessing game?

I already provided you the info...
You were only answering the first line, about mailing to the list, though...
It would help if you actually would read the emails instead of going off-topic
about reply-to munging.
Geez.

I have no idea whether this is a game, but I did tell you already that
there is -graft-points. Did you read the man page?

As I understand it that requires me to rename the file. What am I missing?

Assume I have two files:

c:\foo.avi
f:\bar\quux.avi

How do I make mkisofs create an image containing both, without moving or
renaming them?

No. Why do you think so?
The -graft-points option allows you to _map_ a filename on a local filesystem to
the same _or_ a different filename on the iso filesystem.

-graft-points /usr/local/file1=/usr/local/file1 /usr/file2=/usr/file2 ...
Backslashes probably have to be escaped, but I don't know that for sure. I run
Linux...

If you need backslaches or equal signs in the path name, you need to escape
them. Note that the backslash is not a pathname delimitier, the standard path
name delimiter is "/" and if you feed mkisofs with backslashes in file names on
DOS, you may see funny effects.
