Mounting CDROM with file and directory names in uppercase

tangle · 03-25-2011, 03:16 PM

We have an application that on a SCO box that we are converting to Linux. Basically it mount a CDROM drive and pulls data files off of it. We can mount the drive and it displays all the file/directory names in uppercase. Is there a way to do it in Linux? Thanks

The man page for mount says that ISO 9660 only allows upper case file names in 8.3 format. It further states that Rock Ridge extensions make mixed case file names possible. This leads me to think that if you mount the CD with Rock Ridge extensions disabled then the names may appear in all uppercase.

Quote from man mount:

Quote:

Mount options for iso9660
ISO 9660 is a standard describing a filesystem structure to be used on
CD-ROMs. (This filesystem type is also seen on some DVDs. See also the
udf filesystem.)

Normal iso9660 filenames appear in a 8.3 format (i.e., DOS-like
restrictions on filename length), and in addition all characters are in
upper case. Also there is no field for file ownership, protection,
number of links, provision for block/character devices, etc.

Rock Ridge is an extension to iso9660 that provides all of these unix
like features. Basically there are extensions to each directory record
that supply all of the additional information, and when Rock Ridge is
in use, the filesystem is indistinguishable from a normal UNIX filesys‐
tem (except that it is read-only, of course).

norock Disable the use of Rock Ridge extensions, even if available. Cf.
map.

Tried the iso9660, but it put a ;1 on the end of every file. Thanks
