DESCRIPTION

       The prtvtoc command allows the contents of the label to be viewed. The command can be used only by the super-user.

       The  device  name  can  be the file name of a raw device in the form of /dev/rdsk/c?t?d?s2 or can be the file name of a block device in the
       form of /dev/dsk/c?t?d?s2.

OPTIONS

       The following options are supported:

       -f	       Report on the disk free space, including the starting block address of the free space, number of blocks, and unused  parti-
		       tions.

       -h	       Omit the headers from the normal output.

       -m mnttab       Use mnttab as the list of mounted filesystems, in place of /etc/mnttab.

       -s	       Omit all headers but the column header from the normal output.

EXAMPLES

       Example 1: Using the prtvtoc Command

       The following example uses the prtvtoc command on a 424-megabyte hard disk:

       example# prtvtoc /dev/rdsk/c0t3d0s2
       * /dev/rdsk/c0t3d0s2 partition map
       *
       * Dimension:
       *     512 bytes/sector
       *      80 sectors/track
       *       9 tracks/cylinder
       *     720 sectors/cylinder
       *    2500 cylinders
       *    1151 accessible cylinders
       *
       * Flags:
       *   1: unmountable
       *  10: read-only
       * *			     First    Sector   Last
