.SH NAME
@IMAGEX_PROGNAME@-update \- Update a WIM image
-
.SH SYNOPSIS
\fB@IMAGEX_PROGNAME@ update\fR \fIWIMFILE\fR [\fIIMAGE\fR] [\fIOPTION\fR...] < \fICMDFILE\fR
-
.SH DESCRIPTION
-.PP
-
\fB@IMAGEX_PROGNAME@ update\fR modifies the specified \fIIMAGE\fR in the Windows
Imaging (WIM) file \fIWIMFILE\fR by adding, deleting, or renaming files or
directories in it.
-
+.PP
\fIIMAGE\fR specifies the image in \fIWIMFILE\fR to update. It may be a 1-based
index of an image in the WIM or the name of an image in the WIM. Use the
\fB@IMAGEX_PROGNAME@ info\fR (1) command to list the images a WIM file contains.
\fIIMAGE\fR may be omitted if \fIWIMFILE\fR contains only one image.
-
+.PP
The modifications to perform on the WIM image are specified as a sequence of
commands, one per line, read in a text file from standard input. It is
recommended that standard input be redirected from a file (\fICMDFILE\fR), as
shown above, rather than typing in commands interactively.
-
.SH AVAILABLE COMMANDS
-
This section documents the commands that may appear in the \fICMDFILE\fR
described above.
-
.SS \fBadd\fR [\fIOPTION\fR...] \fISOURCE\fR \fIDESTINATION\fR
-Adds a file or directory tree to the WIM image. \fISOURCE\fR must specify the
+Add a file or directory tree to the WIM image. \fISOURCE\fR must specify the
path to a file or directory on your filesystem. \fIDESTINATION\fR must specify
the path inside the WIM image at which to add the file or directory tree. If
-\fIDESTINATION\fR already exists in the WIM image, then an overlay is attempted;
-this can be used to add multiple files to an existing directory in the WIM image
-in one command.
-
+\fIDESTINATION\fR already exists in the WIM image, then an overlay is attempted
+if it is a directory; this feature can be used to add multiple files to an
+existing directory in the WIM image in one command. If \fIDESTINATION\fR does
+not exist in the WIM image, then any prerequisite directories are created as
+needed to add the \fISOURCE\fR at that location.
+.PP
The available options for the \fBadd\fR command are:
-
.TP 6
\fB--verbose\fR
Print the names of files as they are captured.
desire that all security descriptors be captured exactly, you may wish to
provide this option, although the Administrator should have permission to read
everything anyway.
-
.SS \fBdelete\fR [\fIOPTION\fR...] \fIPATH\fR
-Deletes a file or directory tree from a WIM image. \fIPATH\fR must specify the
+Deletes a file or directory tree from the WIM image. \fIPATH\fR must specify the
path inside the WIM image of the file or directory tree to delete.
-
+.PP
The available options for the \fBdelete\fR command are:
-
.TP 6
\fB--force\fR
Do not issue an error if the path to delete does not exist.
\fB--recursive\fR
Delete the file or directory tree recursively; if not specified, an error is
issued if the path to delete is a directory.
-
.SS \fBrename\fR \fIOLD_PATH\fR \fINEW_PATH\fR
-Renames a file or directory tree inside a WIM image. \fIOLD_PATH\fR must
+Renames a file or directory tree inside the WIM image. \fIOLD_PATH\fR must
specify the old path of the file or directory tree inside the WIM image, and
\fINEW_PATH\fR must specify the new path for the file or directory tree. This
command follows the semantics of the POSIX \fBrename\fR (3) function; in
particular, a pre-existing file at \fINEW_PATH\fR will be deleted if present,
except in certain cases such as attempting to rename a directory to a
non-directory, which is not allowed.
-
+.PP
There are no options available for the \fBrename\fR command.
-
.SH OPTIONS
-
+The following options are accepted on the command line by \fB@IMAGEX_PROGNAME@
+update\fR itself:
.TP 6
\fB--verbose\fR
Use \fB--verbose\fR for all \fBadd\fR commands.
Rebuilding the WIM is slower, but will save a little bit of space that would
otherwise be left as a hole in the WIM. Also see
\fB@IMAGEX_PROGNAME@-optimize\fR (1).
-
.SH NOTES
-
\fB@IMAGEX_PROGNAME@ update\fR is partly redundant with \fB@IMAGEX_PROGNAME@
mountrw\fR, since if a WIM image can be mounted read-write, then there
theoretically is no need for \fB@IMAGEX_PROGNAME@ update\fR. The main advantage
-of \fB@IMAGEX_PROGNAME@ update\fR is that is works on both UNIX and Windows,
+of \fB@IMAGEX_PROGNAME@ update\fR is that it works on both UNIX and Windows,
whereas \fB@IMAGEX_PROGNAME@ mountrw\fR only works on UNIX.
-
+.PP
Symbolic links inside a WIM image are not dereferenced when being interpreted.
So, for example, if you have a WIM image that contains a symbolic link
"/Documents and Settings" -> "/Users" where "/Users" is a directory, then a
subdirectory named "Public" in this directory must be specified as
"/Users/Public" rather than "/Documents and Settings/Public".
-
+.PP
+All paths to files or directories within the WIM image must be specified
+relative to the root of the image. However, the leading slash is optional, and
+both forward slashes and backslashes are accepted.
+.PP
The command file (\fICMDFILE\fR) is parsed by \fB@IMAGEX_PROGNAME@ update\fR
itself and not by the system shell. Therefore, its syntax is limited. However,
comment lines beginning with '#' are allowed, and it is also possible to quote
arguments with whitespace inside them.
-
+.PP
On UNIX, you cannot use \fB@IMAGEX_PROGNAME@ update\fR to add files to an image
directly from a NTFS volume using libntfs-3g, even though \fB@IMAGEX_PROGNAME@
capture\fR supports capturing a full image this way.
-
+.PP
It is safe to abort an \fB@IMAGEX_PROGNAME@ update\fR command partway through;
however, after doing this, it is recommended to run \fB@IMAGEX_PROGNAME@
optimize\fR to remove any data that was appended to the physical WIM file but
-not yet incorporated into the structure of the WIM.
-
+not yet incorporated into the structure of the WIM, unless \fB--rebuild\fR was
+specified, in which case you should delete the temporary file left over.
