CPT (COPY_TREE) -- Copy a directory tree.
usage: CPT source_pathname target_pathname [-C|-R|-MS|-MD] [-F] [-CHN]

[-LD] [SUBS] [-LF] [-LL] [-LDL]
[-PR pathname...] [-PDT] {CL}
FORMAT
CPT source_pathname target_pathname ... [options]
CPT is a multipurpose tool for copying, merging, and replacing files,
directories, and links. To copy files only, use CPF (COPY_FILE).
ARGUMENTS
Multiple source/target pairs and wildcarding are permitted.
source_pathname
(required) Specify the file, link, or directory tree to be copied.
CPT does not change the contents or link references of the
source, so errors that occur will leave the source
unaffected.
target_pathname
(required) Specify the file or directory tree to be created, replaced,
or merged. The target pathname may be derived from the
source pathname. The target can NOT be a link. In
addition, the target can NOT be a logical volume entry
directory, or the network root unless the -MD option is
specified.
OPTIONS
Default options are indicated by "(D)."
-AF date Copy only objects whose dtms (date-times) are after the
given date and time:
[[[yy]yy/]mm/dd][.][hh:mm[:ss]] | TODAY . The date
defaults to today, and the time to midnight, if either are
omitted from 'date'.
-BE date Copy only objects whose dtms are before the given date and
time: [[[yy]yy/]mm/dd][.][hh:mm[:ss]] | TODAY . The date
defaults to today, and the time to midnight if either are
omitted from 'date'.
-C (D) Create source at target. If the file or directory already
exists, an error will occur and processing will continue to
the next source/target pair. Not valid if -MS, -MD, or -R
is specified.
If the source is a file, CPT copies it to the target. If
the source is a directory, CPT copies the directory to the
target. It then copies every file cataloged in the
directory (and all subdirectories) until it reaches the end
of the tree.
Each link name in the source tree is created as a link name
in the target, but the object that the link references is
not copied. If 'source_pathname' is itself a link,
however, the link is resolved and the object to which it
points is copied to the target.
-R Replace target with source. Not valid if -C ,-MS, or -MD
is specified. CPT deletes the tree starting at the target
pathname and copies the entire source tree in its place. If
no target tree by the specified name exists, CPT creates
one and duplicates the source.
-MS Merge source and target if both are directories. Not valid
if -C or -R is specified. If the target does not exist,
CPT duplicates the source at the target. If the target
exists, CPT merges the source into the target, replacing
files and links, and combining directories.
If both the source and the target are directories, CPT
merges their contents as described below. Otherwise, CPT
deletes the target and replaces it with the source.
To merge directories, CPT compares their contents, object
by object. Objects that exist in the source but not in the
target are created in the target. Objects that exist in
the target but not in the source remain unchanged. Files
and links with the same name in both the source and the
target are deleted from the target and replaced by the
source version. Directories with the same name in both
source and target are merged. CPT continues this process
interactively until it reaches the end of the source tree.
-MD Merge source and target if both are directories. Similar
to -MS except that files and links with the same name in
both source and target are left unchanged in the target.
-F Force deletion of target object if 'p' rights are present.
-DACL (D) Apply the target directory's default ACLs. In addition to
its own ACL, each directory has two default ACLs, one for
its files and another for its subdirectories. -DACL causes
CPT to apply the target directory's default ACLs to each
subdirectory and file it copies. The -SACL option causes
each object to retain its original ACL.
-SACL Retain the source ACL.
-CHN Use with -C to change the name of a target before source is
copied. Use if target_name already exists. Use with -R,
-MS, and -MD to change the target_name if target is in use.
-SUBS Retain the source ACLs for objects which belong to
subsystems.
-PR pathname Preserve the object 'pathname' in target when another
object with the same name exists in the source. Valid with
-MS option only.
-PDT Preserve the source's modification and used times.
The following five options allow you to monitor CPT's operation. You can use
-LD, -LF, and -LL in any combination. By default, the listing options apply to
both copied and deleted objects. To list only deletions, use -LDL with -L,
-LD, -LF, or -LL.
-L List all objects as they are copied.
-LD List directories as they are copied.
-LF List files as they are copied.
-LL List links as they are copied.
-LDL List only objects deleted as a result of replacements.
This command uses the command line parser, and so also accepts the standard
command options listed in HELP CL.
EXAMPLES
1. $ cpt /com /com.backup -r Copy the directory tree "/com"
to "/com.backup" replacing the
existing "/com.backup" tree.
2. $ cpt my_circuits /circuits -ms Merge the directory tree
"my_circuits" into the
"/circuits" tree.
