NAME
     ppddiisskk - Apple partition table editor

SYNOPSIS
     ppddiisskk [-aaccddffhhiillLLrrvv] [--aabbbbrr] [--ccoommppuutteessiizzee] [--ddeebbuugg] [--ffnnaammee]
           [--hheellpp] [--iinntteerraaccttiivvee] [--lliisstt] [--llooggiiccaall] [--rreeaaddoonnllyy]
           [--vveerrssiioonn] [device ...]

DESCRIPTION
     ppddiisskk is a menu driven program which partitions disks using the standard
     Apple disk partitioning scheme described in "Inside Macintosh: Devices".
     It does not support the Intel/DOS partitioning scheme supported by
     fdisk(8).

     Supported options are:
     -aa
     --aabbbbrr            Abbreviate the partition types shown in the partition
                       list.
     -cc
     --ccoommppuutteessiizzee    Causes ppddiisskk to always ignore the device size listed in
                       the partition table and compute the device size by
                       other means.
     -dd
     --ddeebbuugg           Turns on debugging.  Doesn't add that much output, but
                       does add a new command `x' to the editing commands that
                       accesses an eclectic bunch of undocumented functional-
                       ity.
     -ff
     --ffnnaammee           Show HFS volume names instead of partition name when
                       available.
     -hh
     --hheellpp            Prints a short help message.
     -ii
     --iinntteerraaccttiivvee     Causes ppddiisskk to go into an interactive mode similar to
                       the MacOS version of the program.
     -ll
     --lliisstt            If no device argument is given, ppddiisskk tries to list
                       partition tables for all available drives.  Otherwise,
                       ppddiisskk lists the partition tables for the specified
                       devices.
     -LL
     --llooggiiccaall         Show partition limits in logical blocks.  Default is
                       physical blocks.
     -rr
     --rreeaaddoonnllyy        Prevents ppddiisskk from writing to the device.
     -vv
     --vveerrssiioonn         Prints the version number of ppddiisskk.

     An argument which is simply the name of a device indicates that ppddiisskk
     should edit the partition table of that device.

     The current top level editing commands are:

           C    (create with type also specified)
           c    create new partition
           d    delete a partition
           h    command help
           i    initialize partition map
           n    (re)name a partition
           P    (print ordered by base address)
           p    print the partition table
           q    quit editing (don't save changes)
           r    reorder partition entry in map
           s    change size of partition map
           t    change the type of an existing partition
           w    write the partition table

     Commands which take arguments prompt for each argument in turn.  You can
     also type any number of the arguments separated by spaces and those
     prompts will be skipped.  The only exception to typeahead are the confir-
     mation prompts on the ii and ww commands, since if we expect you to confirm
     the decision, we shouldn't undermine that by allowing you to be precipi-
     tate about it.

     Partitions are always specified by their number, which is the index of
     the partition entry in the partition map.  Most of the commands will
     change the index numbers of all partitions after the affected partition.
     You are advised to print the table as frequently as necessary.

     The cc (create new partition) command is the only one with complicated
     arguments.  The first argument is the base address (in blocks) of the
     partition.  Besides a raw number, you can also specify a partition number
     followed by the letter `p' to indicate that the first block of the new
     partition should be the same as the first block of that existing free
     space partition.  The second argument is the length of the partition in
     blocks.  This can be a raw number or can be a partition number followed
     by the letter `p' to use the size of that partition or can be a number
     followed by `k', `m', or `g' to indicate the size in kilobytes,
     megabytes, or gigabytes respectively.  (These are powers of 1024, of
     course, not powers of 1000.)  The third argument is the name of the par-
     tition.  This can be a single word without quotes, or a string surrounded
     by single or double quotes.

     The CC command is similar to the cc command, with the addition of a parti-
     tion type argument after the other arguments.

     The ii (initalize) command prompts for the size of the device.

     The nn (name) command allows the name of a partition to be changed.

     The rr (reorder) command allows the index number of partitions to be
     changed.  The index numbers are constrained to be a contiguous sequence.

     The tt (change partition type) command allows the type of a partition to
     be changed.

     The ww (write) command writes the partition map out.

HISTORY     The ppddiisskk utility was originally developed for MkLinux.

BUGS
     Some people believe there should really be just one disk partitioning
     utility.

     Filesystem volume names are out of place in a partition utility.  This
     utility supports HFS volume names, but not volume names of any other
     filesystem types.

     The --llooggiiccaall option has not been heavily tested.
