DESCRIPTION
Copy source to DEST, or multiple source (s) to DIRECTORY.

Mandatory arguments to long options is Mandatory for short options too.

*********************************************************************************
-A,--archive
Same AS-DR--preserve=all

-R,-R,--recursive
Copy directories recursively

-d Same as--no-dereference--preserve=links

# Copy only links without copying related files, keep links

-P,--no-dereference
Never follow symbolic links in SOURCE

-L,--link
Hard link files instead of copying

-L,--dereference
Always follow symbolic links in SOURCE

-S,--symbolic-link
Make symbolic links instead of copying

-H Follow command-line symbolic links in SOURCE
********************************************************************************

      --attributes-only #仅复制自己所拥有的
               don ' t copy the file data, just the attributes

       --backup[=control]
               make a backup of each existing destination file

      -b      like--backup but does not accept an argument

      --copy-contents< br>              copy contents of special files When recursive

 
******************************************************************************* *****************************

      -F,--force
               If an existing destination file cannot being opened, remove it and try again (this option is I gnored when The-n option is also used)

      -I,--interactive
  & nbsp;           Prompt before overwrite (overrides a previous-n option)


      -N,--no-clobber
               do not overwrite an existing file (Overrides a previous-i option)

-U,--update
Copy only if the SOURCE file is newer than the destination file or when the destination file is missing

-V,--verbose
Explain what's being done

****************************************************************************************************

Some information about the file changes during the copy process, and we use the following options to persist or discard the information:

-p Same as--preserve=mode,ownership,timestamps

--preserve[=attr_list]
Preserve the specified attributes (default:mode,ownership,timestamps), if possible additional attributes:context, links , Xattr, all
Rights owner Timestamp Content link all
--no-preserve=attr_list
Don ' t preserve the specified attributes

********************************************************************************************************

--parents
Use full source file name under DIRECTORY


--reflink[=when]
Control Clone/cow copies. See below

--remove-destination
Remove each existing destination file before attempting to open it (contrast with--force)

--sparse=when
Control creation of sparse files. See below

--strip-trailing-slashes
Remove any trailing slashes from each SOURCE argument


-S,--suffix=suffix
Override the usual backup suffix

-T,--target-directory=directory
Copy all SOURCE arguments to DIRECTORY

-T,--no-target-directory
Treat DEST as a normal file



-X,--one-file-system
Stay on the This file system

--help Display this Help and exit

--version
Output version information and exit

By default, sparse SOURCE files was detected by a crude heuristic and the corresponding DEST file is made sparse as  Well. That's the
Behavior selected by--sparse=auto. Specify--sparse=always to create a sparse DEST file whenever the SOURCE file contains a long enough
Sequence of zero bytes. Use--sparse=never to inhibit creation of sparse files.

When--reflink[=always] was specified, perform a lightweight copy, where the data blocks was copied only when modified. If This is not pos‐
Sible the copy fails, or if--reflink=auto is specified and fall back to a standard copy.

The backup suffix is ' ~ ', and unless set with--suffix or Simple_backup_suffix. The version control method may be selected via the--backup
option or through the VERSION_CONTROL environment variable. Here is the values:

None, off
Never make backups (even if--backup is given)

Numbered, T
Make numbered backups

Existing, nil
Numbered if numbered backups exist, simple otherwise

Simple, never
Always do simple backups

As a special case, CP makes a backup of SOURCE when the force and backup options is given and SOURCE and DEST is th E same name for an
Existing, regular file.
