If you think about it a file with nothing in it only has a newline in it...
Because the file as "spaces followed by a newline". So your answer is yes. But the file has to be empty for this to be the case.
That is probably why my 0 byte test failed.
here is my output using your test criteria.
-root:/tmp> echo "" > test # no blank in between
-root:/tmp> od -b test
0000000 012
0000001
-root:/tmp> echo > test #echo nothing
-root:/tmp> od -b test
0000000 012
0000001
-root:/tmp> echo " " > test # echo one blank character
-root:/tmp> od -b test
0000000 040 012

libntfs-gnomevfs
NTFSPROGS(8) System Manager's Manual NTFSPROGS(8)
NAME
libntfs-gnomevfs - Module for GNOME VFS that allows access to NTFS filesystems.
OVERVIEW
The GNOME virtual filesystem (VFS) provides universal access to different filesystems. The libntfs-gnomevfs module enables GNOME VFS aware
clients to seamlessly utilize the NTFS library libntfs.
So you can access an NTFS filesystem without needing to use the NTFS utilities themselves (at least in theory anyway). In practice this is
probably more useful for programs and programmers to make using libntfs easier, more generic, and to allow easier debugging of libntfs.
Examples
Prerequisites
To be able to follow these examples you will need to have installed the test utilities from the gnome-vfs-2.4.x package. The easiest way
to do this is to download and compile the gnome-vfs-2 package, e.g. download from:
http://ftp.gnome.org/pub/GNOME/desktop/2.4/2.4.0/sources/gnome-vfs-2.4.0.tar.gz
Then run ./configure followed by make and make install (as root). This will install it into /usr/local so it should not conflict with your
existing installation from rpm or deb packages which will be in /usr.
Note you may also need to add /usr/local/lib to /etc/ld.so.conf and then run ldconfig (as root) to let your system see the installed gnome-
vfs-2.4.x libraries.
Then run ./configure followed by make and make install (as root) in the main ntfsprogs directory to build and install the libntfs-gnomevfs
module and libntfs library which is used by the module.
Copying a file from an NTFS partition
To copy the file autoexec.bat from the main directory of an NTFS partition (/dev/hda1) to the /tmp directory on your system you could run:
/path/to/gnome-vfs-2.4.x/test/test-xfer file:///dev/hda1#libntfs:/autoexec.bat /tmp/autoexec.bat
To copy a file from a directory inside the NTFS partition you would just specify the full path. So for example to copy the file win.ini
from the Windows directory you would run:
/path/to/gnome-vfs-2.4.x/test/test-xfer file:///dev/hda1#libntfs:/Windows/win.ini /tmp/win.ini
Shell access to an NTFS partition
For debugging it is most useful to be able to do various things to the NTFS partition while it is being operated upon by libntfs. This is
achieved using the test-shell utility (from the gnome-vfs-2.4.x package) by running: /path/to/gnome-vfs-2.4.x/test/test-shell
This drops you into the GNOME VFS shell from where you can now cd into the NTFS partition (/dev/hda1) by typing: cd file:///dev/hda1#lib-
ntfs:/
You are now in the root directory of the NTFS partition. The first thing you will probably want to do is to type "ls" to display the
directory contents.
You could then change directories using the "cd" command, e.g. to enter the Windows directory you would type: cd Windows
You can then open files, seek inside files, read from files (write is not enabled at present), etc thus exercising large portions of the
NTFS library.
Use the "help" command while in the shell to see the available commands.
BUGS
No bugs are known but there are several limitations at the moment:
You cannot get information about files other than what the "ls" command in the test-shell can give you, i.e. the "info" command in the
test-shell does not work.
Further access to the partition is read-only and hence you cannot write to files. This will be changed in the future once the module has
had more wide testing.
There may be other limitations and possibly bugs. Please report any problems to the NTFS mailing list: linux-ntfs-dev@lists.source-
