reads from the named file on the remote host using

.Pp
+.It Fl F Ar script
+Run script at the beginning of each tape. The device name and the
+current volume number are passed on the command line.
+The script must return 0 if
+.Nm
+should continue without asking the user to change the tape, 1 if
+.Nm
+should continue but ask the user to change the tape.
+Any other exit code will cause
+.Nm
+to abort.
+For security reasons,
+.Nm
+reverts back to the real user ID and the real group ID before
+running the script.
.It Fl k
Use Kerberos authentication when contacting the remote tape server.
(Only available if this options was enabled when
rather than the files that it references.
This prevents hierarchical restoration of complete subtrees
from the dump.
+.It Fl l
+When doing remote restores, assume the remote file is a
+regular file (instead of a tape device). If you're restoring
+a remote compressed file, you will need to specify this
+option or
+.Nm restore
+will fail to access it correctly.
.It Fl m
Extract by inode numbers rather than by file name.
This is useful if only a few files are being extracted,
.Ar file
in order to read tape position as stored using the dump Quick File
Access mode.
+.Pp
+It is recommended to set up the st driver to return logical tape
+positions rather than physical before calling dump/restore with
+parameter Q. Since not all tape devices support physical tape
+positions those tape devices return an error during dump/restore when
+the st driver is set to the default physical setting.
+Please see the st man page, option MTSETDRVBUFFER, or the mt man
+page, on how to set the driver to return logical tape positions.
+.Pp
+Before calling restore with parameter Q, always make sure the st
+driver is set to return the same type of tape position used during the
+call to dump. Otherwise restore may be confused.
.It Fl s Ar fileno
Read from the specified
.Ar fileno
(verbose)
flag causes it to type the name of each file it treats
preceded by its file type.
+.It Fl V
+Enables reading multi-volume non-tape mediums like CDROMs.
.It Fl X Ar filelist
Read list of files to be listed or extracted from the text file
.Ar filelist
If this variable is not set,
.Xr rcmd 3
will be used, but only root will be able to do a network restore.
