.SH NAME
tar \- an archiving utility
.SH SYNOPSIS
\fB\-\-remove\-files\fR
Remove files from disk after adding them to the archive.
.TP
+\fB\-\-skip\-old\-files
+Don't replace existing files when extracting, silently skip over them.
+.TP
\fB\-U\fR, \fB\-\-unlink\-first\fR
Remove each file prior to extracting over it.
.TP
.TP
\fB\-s\fR, \fB\-\-preserve\-order\fR, \fB\-\-same\-order\fR
Sort names to extract to match archive
+.TP
+\fB\-\-sort=\fIORDER\fR
+When creating an archive, sort directory entries according to
+\fIORDER\fR, which is one of
+.BR none ,
+.BR name ", or"
+.BR inode .
+
+The default is \fB\-\-sort=none\fR, which stores archive members in
+the same order as returned by the operating system.
+
+Using \fB\-\-sort=name\fR ensures the member ordering in the created archive
+is uniform and reproducible.
+
+Using \fB\-\-sort=inode\fR reduces the number of disk seeks made when
+creating the archive and thus can considerably speed up archivation.
+This sorting order is supported only if the underlying system provides
+the necessary information.
