file names lower-cased on cp from CD

[Joel Rees]

Not sure if this is OT or not, but I'll ask anyway.

The CD was apparently burned on a MSWxxx box with a shift-jis file
system. (At any rate, there are shift-jis file names in the mix.) 

That the shift-jis file names get mojibake-d is one thing, but latin
file names throughout the CD come out all lower-case, which of course
mucks up javac.

Anybody with any ideas as to why, and as to how to get around this kind
of behavior?

[Joel Rees]

Okay, I've dug around a bit and (re-)discovered Joliet extensions.

For the record,

If that isn't clear, the result is that 

    jp/domain/package/ThisCamelCaseClass.java

on the CD (as mounted by MSWxp and, from what my co-worker here tells 
me, Solaris) shows up and is copied as 

    jp/domain/package/thiscamelcaseclass.java

when the CD is mounted on Fedora Core 4.

I was looking for a way to grep into shift-jis files, and found lv and 
other information that pointed to the Joliet extensions. So I looked at 
mount and see the map options in the manual.

Apparently the map options to mount are by default forcing the CD to 
map everything lower-case. In addition to the problems I have with Java 
source file names, I'm guessing this has screwed up the shift-jis file 
names copying in from CD.

(shift-jis is another of the reasons I consider microsop^Hft a company 
of tech thieves who have never been able to really fix the messes 
caused by the bad tech they have acquired to "get the job done now" by 
hardware insufficient to the task. But I digress.)

So I guess I need to figure out where the default map options (for 
automount?) are set. Or, perhaps, to remember to 

    umount
    mount -o map=off 

or something. (I'll have to see if that works next time we get the CD 
out of the safe.)

Have you tried changing the fstab "options" column entry?
You might try putting "nojoliet" in there for an alternate
mount point. There's also a "case=<code>", documented for
HPFS and HFS. It might also work for ISO9660. You might
try "case=asis". The default (since 2.2.x) has been
"case=lower".

Mike,

This may be a stupid question, but where did you come up with your
answer? I have manned fstab and mount, but see no mention of case,
joliet, etc in there or on any other resource that google points me to
when searching for fstab.

I am not doubting you- rather I am trying to build my arsenal of
resources. I do not plan on getting a degree in computer science, so I
therefore need to know from where to get answers without constantly
nagging the list with newbie questions.

In any case, I am currently having fstab related trouble, that I am
trying to sort out on my own (with Hebrew filenames on a FAT32
partition). So any fstab-related resource would be welcome.

I'm not Mike, but I suspect he's been looking in the documentation that
comes with the Linux kernel source.

On Fedora Core 4, you can install the kernel-doc RPM, cd to
/usr/share/doc/kernel-doc-2.6.*, and look in the
Documentation/filesystems folder.

Or you can download a tarball of the source, or somewhere like
http://www.linuxhq.com/kernel/v2.6/15/Documentation/filesystems/ .

It's well worth being aware of this documentation -- there's a lot of
good technical points in there.

Hope this helps,

James.

The mount options Mike referred to are all mentioned in "man mount" 
actually, at least in FC4.

My mount man file has information about both of them in the ISO9660
section.  In case you don't know, you can search through man files by
pressing slash then the term that you're after.  e.g. /iso9660

Well, from a variety of sources. I have a book on Linux Admin which
I find useful. But these particular pieces of information can be
found in

$ man mount

Well, not the part about which kernels had these options...

Sounds like a good plan.

I don't know how that works. Sorry. But Google for

+hebrew +file +name +FAT32 +linux

turned up several hits, some of which look promising, one in
particular has some info like this...

Interesting.  I had some files on Win98SE with foreign characters that
never even showed up in listings through SMB on the Linux box.  I ended
up just renaming them.  But if they're UTF-16, there shouldn't be any
need for translation options.  Linux should know they're all UTF-16, and
your local system ought to be identified by itself.
