NAME
       cpd - change or view the allocation limits for a control point
       directory

SYNOPSIS
       cpd [ -b blocks ] [ -f file-nodes ] dirname ...

DESCRIPTION
       If no options are given, cpd displays the current allocation and the
       maximum allocation of blocks and file nodes for each control point
       directory named on the command line.  If the -b or -f option is
       given, the allocation limits of the control point directory are
       changed as described below:

       -b blocks Set the maximum block allocation to blocks.  This is the
                 maximum number of blocks that can be allocated to this
                 directory and all of its descendants.  Alternatively, you
                 may specify the maximum in bytes instead of blocks.  To do
                 this, append the appropriate suffix to the -b option value:
                 b for bytes, k for kilobytes (1024 bytes), m for megabytes
                 (1,048,576 bytes), and g for gigabytes (1,073,741,824
                 bytes).  For example, -b 5m sets a limit of 5 megabytes on
                 the amount of space that can be allocated for the directory
                 and all its descendants.  The letter suffix may be upper or
                 lower case.  Note that the byte size may be rounded down by
                 cpd to be a multiple of the block size.

       -f file-nodes
                 Set the file node allocation limit to file-nodes.  This is
                 the maximum number of file nodes that can be allocated to
                 this directory and all of its descendants.  file-nodes may
                 include a "k", "m", or "g" suffix.

       In order to change the allocation limits for a CPD, the user must
       have write permission in the parent directory (owning the CPD is not
       sufficient).  In the case where the CPD is the root of a file system,
       only the superuser can change the limits.

       The last component of dirname may not be "." or "..".  Use an
       absolute pathname instead.

       The limits for a CPD may be resized to any value between 0 and the
       system maximum.  Note that it is not a requirement that either
       allocation limit be greater than the current allocation.

       To create a control point directory, use the mkdir(1) command.

DIAGNOSTICS
       cpd returns a nonzero status code if any of the dirnames does not
       exist, is not a CPD, is not on a local file system, or has a last
       component of "." or "..".  Otherwise, 0 is returned.
