volcopy, labelit - copy a file system with label checking
SYNOPSIS
[options] fsname special1 volname1 special2 volname2
[options] special [fsname volume
DESCRIPTION
The command makes a literal copy of the file system using a block size
matched to the device.
Options
recognizes the following options:
Specify the file system type on which to operate (see
fstyp(1M) and fs_wrapper(5)). If this option is
not included on the command line, then the file
system type is determined from the file by match‐
ing special with an entry in that file. If there
is no entry in then the file system type is
determined from the file
Invoke a verification sequence
requiring a positive operator response instead of
the standard delay before the copy is made.
Specify options specific to the file system type.
specific_options is a list of suboptions and/or
keyword/attribute pairs intended for an FStype-
specific module of the command. See the file
system specific manual entries for a description
of the specific_options that are supported, if
any.
(default) Invoke the DEL-if-wrong verification sequence.
Assume a response to all questions
Echo the completed command line, but perform no other actions.
The command line is generated by incorporating
the user-specified options and arguments with
other information derived from This option allows
the user to verify the command line.
Other options are used with 9-track magnetic tapes:
Bits per inch.
Size of reel in feet.
Beginning reel number for a restarted copy.
Use double buffered I/O.
The command requests length and density information if they are not
given on the command line and they are not recorded on an input tape
label. If the file system is too large to fit on one reel, the command
prompts for additional reels. Labels of all reels are checked. Tapes
can be mounted alternately on two or more drives. If the command is
interrupted, it asks if the user wants to quit or wants to escape to
the command interpreter. In the latter case, other operations (such as
executing the command) can be performed before returning to the command
by exiting the command interpreter.
fsname The file system name on the device (e.g., being copied.
special The physical disk section or tape (e.g., or
volname The physical volume name; it should match the external
sticker. Such label names are limited to six or fewer char‐
acters. The argument volname can be to use the existing vol‐
ume name.
special1 The device from which the copy of the file system is being
extracted.
volname1 The volume from which the copy of the file system is being
extracted.
special2 The target device.
volname2 The target volume.
The command can be used to provide initial labels for unmounted disk or
tape file systems. With the optional arguments omitted, the command
prints current label values. The option provides for initial labeling
of new tapes only (this destroys previous contents). The and options
can be specified for the command. The behavior of the and options is
similar to their behavior in the command.
