.SH NAME
@IMAGEX_PROGNAME@-extract \- Extract files or directories from a WIM image
.SH SYNOPSIS

.SH DESCRIPTION
.PP
extract. See \fBPATH_SPECIFICATIONS\fR.
By default, files and directories are extracted to the current directory. Use
-\fB--dest-dir\fR to choose an alternate target directory.
+\fB--dest-dir\fR to choose an alternate target directory. Alternatively, use
+\fB--to-stdout\fR to extract a file to standard output to pipe into another
+program.
\fB@IMAGEX_PROGNAME@ extract\fR supports extracting files and directory trees
from stand-alone WIMs as well as split WIMs. See \fBSPLIT WIMS\fR.
When reading \fIWIMFILE\fR, verify its integrity if the integrity table is
present.
.TP
-\fB--verbose\fR
-Print the path to of each file or directory within the WIM image as it is
-extracted, and some additional informational messages.
-.TP
\fB--ref\fR="\fIGLOB\fR"
File glob of additional split WIM parts that are part of the split WIM. See
\fBSPLIT_WIMS\fR.
.TP
+\fB--verbose\fR
+Print the path to of each file or directory within the WIM image as it is
+extracted.
+.TP
\fB--unix-data\fR
-Restore the UNIX-specific data captured using \fB@IMAGEX_PROGNAME@ capture\fR
-with the \fB--unix-data\fR option. This option is only available on UNIX.
+See the documentation for this option in \fB@IMAGEX_PROGNAME@-apply\fR (1).
.TP
\fB--no-acls\fR
-Do not restore security descriptors on extracted files and directories. This
-option is only available on Windows.
+See the documentation for this option in \fB@IMAGEX_PROGNAME@-apply\fR (1).
.TP
\fB--strict-acls\fR
-Fail immediately if the full security descriptor of any file or directory cannot
-be set exactly as specified in the WIM file. The default behavior without this
-option is to fall back to setting a security descriptor with the SACL omitted,
-then only the default inherited security descriptor, if we do not have
-permission to set the desired one. This option is only available on Windows.
+See the documentation for this option in \fB@IMAGEX_PROGNAME@-apply\fR (1).
.TP
\fB--to-stdout\fR
Extract the files to standard output instead of to the filesystem. This can
only be provided if all the specified \fIPATH\fRs are to regular files (not
directories or reparse points). If present, alternate data streams are not
extracted.
+.TP
+\fB--dest-dir\fR=\fIDIR\fR
+Extract the files and directories to the directory \fIDIR\fR instead of to the
+current working directory.
.SH NOTES
-\fB@IMAGEX_PROGNAME@ extract\fR calculates the SHA1 message digest of every file
-stream it extracts and verifies that it is the same as the SHA1 message digest
-provided in the WIM file. Thus, it should provide assurance of data integrity.
+See the documentation \fB@IMAGEX_PROGNAME@ apply\fR (1) for documentation about
+what data and metadata are extracted on UNIX versus on Windows.
-Reparse-point fixups (a.k.a. changing absolute symbolic links and junction to
+On UNIX, one can alternatively mount the WIM image with \fB@IMAGEX_PROGNAME@
+mount\fR and then extract the desired files or directories using any standard
+command-line or graphical program.
+
+Reparse-point fixups (a.k.a. changing absolute symbolic links and junctions to
point within the extraction location) are never done by \fB@IMAGEX_PROGNAME@
extract\fR. Use \fB@IMAGEX_PROGNAME@ apply\fR if you want this behavior.
Unlike \fB@IMAGEX_PROGNAME@ apply\fR, \fB@IMAGEX_PROGNAME@ extract\fR does not
support extracting files directly to a NTFS volume using libntfs-3g.
-Not all data and metadata containing in each WIM \fIPATH\fR will necessarily be
-extracted, since \fB@IMAGEX_PROGNAME@ extract\fR does the best it can given the
-platform (UNIX or Windows) and supported features of the filesystem. The
-documentation for \fB@IMAGEX_PROGNAME@ apply\fR (1) goes into more detail about
-what data and metadata is extracted and what is not.
