When copying a file through ntfscp, the file size is known, hence the space allocation can be optimized to get minimal fragmentation.

.TH NTFSCP 8 "September 2007" "ntfs-3g @VERSION@"
|
|
.SH NAME
|
|
ntfscp \- copy file to an NTFS volume.
|
|
.SH SYNOPSIS
|
|
\fBntfscp\fR [\fIoptions\fR] \fIdevice source_file destination\fR
|
|
.SH DESCRIPTION
|
|
\fBntfscp\fR will copy file to an NTFS volume. \fIdestination\fR can be either
|
|
file or directory. In case if \fIdestination\fR is directory specified by name
|
|
then \fIsource_file\fR is copied into this directory, in case if
|
|
\fIdestination\fR is directory and specified by inode number then unnamed data
|
|
attribute is created for this inode and \fIsource_file\fR is copied into it
|
|
(WARNING: it's unusual to have unnamed data streams in the directories, think
|
|
twice before specifying directory by inode number).
|
|
.SH OPTIONS
|
|
Below is a summary of all the options that
|
|
.B ntfscp
|
|
accepts. Nearly all options have two equivalent names. The short name is
|
|
preceded by
|
|
.B \-
|
|
and the long name is preceded by
|
|
.BR \-\- .
|
|
Any single letter options, that don't take an argument, can be combined into a
|
|
single command, e.g.
|
|
.B \-fv
|
|
is equivalent to
|
|
.BR "\-f \-v" .
|
|
Long named options can be abbreviated to any unique prefix of their name.
|
|
.TP
|
|
\fB\-a\fR, \fB\-\-attribute\fR NUM
|
|
Write to this attribute.
|
|
.TP
|
|
\fB\-i\fR, \fB\-\-inode\fR
|
|
Treat
|
|
.I destination
|
|
as inode number.
|
|
.TP
|
|
\fB\-m\fR, \fB\-\-min-fragments\fR
|
|
Minimize fragmentation when allocating space to the attribute. This is
|
|
mostly useful when creating big files.
|
|
.TP
|
|
\fB\-N\fR, \fB\-\-attr\-name\fR NAME
|
|
Write to attribute with this name.
|
|
.TP
|
|
\fB\-n\fR, \fB\-\-no\-action\fR
|
|
Use this option to make a test run before doing the real copy operation.
|
|
Volume will be opened read\-only and no write will be done.
|
|
.TP
|
|
\fB\-f\fR, \fB\-\-force\fR
|
|
This will override some sensible defaults, such as not working with a mounted
|
|
volume. Use this option with caution.
|
|
.TP
|
|
\fB\-h\fR, \fB\-\-help\fR
|
|
Show a list of options with a brief description of each one.
|
|
.TP
|
|
\fB\-q\fR, \fB\-\-quiet\fR
|
|
Suppress some debug/warning/error messages.
|
|
.TP
|
|
\fB\-V\fR, \fB\-\-version\fR
|
|
Show the version number, copyright and license
|
|
.BR ntfscp .
|
|
.TP
|
|
\fB\-v\fR, \fB\-\-verbose\fR
|
|
Display more debug/warning/error messages.
|
|
.SH DATA STREAMS
|
|
All data on NTFS is stored in streams, which can have names. A file can have
|
|
more than one data streams, but exactly one must have no name. The size of a
|
|
file is the size of its unnamed data stream. Usually when you don't specify
|
|
stream name you are access to unnamed data stream. If you want access to named
|
|
data stream you need to add ":stream_name" to the filename. For example: by
|
|
opening "some.mp3:artist" you will open stream "artist" in "some.mp3". But
|
|
windows usually prevent you from accessing to named data streams, so you need
|
|
to use some program like FAR or utils from cygwin to access named data streams.
|
|
.SH EXAMPLES
|
|
Copy new_boot.ini from /home/user as boot.ini to the root of an /dev/hda1 NTFS
|
|
volume:
|
|
.RS
|
|
.sp
|
|
.B ntfscp /dev/hda1 /home/user/new_boot.ini boot.ini
|
|
.sp
|
|
.RE
|
|
Copy myfile to C:\\some\\path\\myfile:stream (assume that /dev/hda1 letter in
|
|
windows is C):
|
|
.RS
|
|
.sp
|
|
.B ntfscp \-N stream /dev/hda1 myfile /some/path
|
|
.sp
