volcopy_hfs(1M)						       volcopy_hfs(1M)

NAME
       volcopy_hfs:  volcopy,  labelit	-  copy	 an HFS file system with label
       checking

SYNOPSIS
       [options] fsname special1 volname1 special2 volname2

       [options] special [fsname volume

DESCRIPTION
       The command makes a literal copy of an HFS file system  using  a	 block
       size matched to the device.

   Options
       recognizes the following options:

	      Specifies the HFS file system type.

	      Invoke a verification sequence
			     requiring a positive operator response instead of
			     the standard delay before the copy is made.

	      (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.
