NAME
       cp - copy files and directory subtrees

SYNOPSIS
       extarg ]	file1 new_file

       extarg ]	file1 [file2 ...] dest_directory

       extarg ]	directory1 [directory2 ...] dest_directory

DESCRIPTION
       copies:

	      o	 file1 to new or existing new_file,
	      o	 file1 to existing dest_directory,
	      o	 file1,	file2, ...  to existing	dest_directory,
	      o	 directory  subtree directory1,	to new or existing dest_direc-
		 tory.	or
	      o	 multiple directory subtrees directory1,  directory2, ...   to
		 new or	existing dest_directory.

       fails  if file1 and new_file are	the same (be cautious when using shell
       metacharacters).	 When destination is a directory, one  or  more	 files
       are  copied  into that directory.  If two or more files are copied, the
       destination must	be a directory.	 When copying a	single file to	a  new
       file, if	new_file exists, its contents are destroyed.

       If the access permissions of the	destination dest_directory or existing
       destination file	new_file forbid	writing, aborts	and produces an	 error
       message ``cannot	create file''.

       To copy one or more directory subtrees to another directory, the	option
       is required.  The option	is ignored if used when	copying	a file to  an-
       other file or files to a	directory.

       If  new_file is a link to an existing file with other links, overwrites
       the existing file and retains all links.	 If copying a file to  an  ex-
       isting  file,  does  not	 change	 existing file access permission bits,
       owner, or group.

       When copying files to a directory or to a new file that	does  not  al-
       ready  exist,  creates a	new file with the same file permission bits as
       file1, modified by the file creation mask of the	user if	the option was
       not  specified,	and  then  bitwise inclusively ORed with S_IRWXU.  The
       owner and group of the new file or files	are those of  the  user.   The
       last  modification  time	of new_file (and last access time, if new_file
       did not exist) and the last access time of the source file1 are set  to
       the time	the copy was made.

   Options
       (interactive copy) Cause
	       to write	a prompt to standard error and wait for	a response be-
	       fore copying a file that	would overwrite	an existing file.   If
	       the  response  from the standard	input is affirmative, the file
	       is copied if permissions	allow the copy.	 If the	 (interactive)
	       and (forced-copy) options are both specified, the option	is ig-
	       nored.

       Force existing destination pathnames to be removed before copying,
	       without prompting for confirmation.  This option	has the	effect
	       of  destroying  and  replacing any existing file	whose name and
	       directory location conflicts with the name and location of  the
	       new file	created	by the copy operation.

       (preserve permissions) Causes
	       to  preserve  in	the copy as many of the	modification time, ac-
	       cess time, file mode, user ID, and group	ID as allowed by  per-
	       missions.

       (recursive subtree copy)	Cause
	       to copy the subtree rooted at each source directory to dest_di-
	       rectory.	 If dest_directory exists, it must be a	directory,  in
	       which  case  creates a directory	within dest_directory with the
	       same name as file1 and copies the subtree rooted	 at  file1  to
	       dest_directory/file1.   An error	occurs if dest_directory/file1
	       already exists.	If dest_directory does not exist,  creates  it
	       and copies the subtree rooted at	file1 to dest_directory.  Note
	       that cannot merge subtrees.

	       Usually normal files and	 directories  are  copied.   Character
	       special	devices, block special devices,	network	special	files,
	       named pipes, symbolic links, and	sockets	 are  copied,  if  the
	       user  has  access  to the file; otherwise, a warning is printed
	       stating that the	file  cannot  be  created,  and	 the  file  is
	       skipped.

	       dest_directory  should not reside within	directory1, nor	should
	       directory1 have a cyclic	directory  structure,  since  in  both
	       cases attempts to copy an infinite amount of data.

       (recursive subtree copy)	The
	       option  is  identical to	the option with	the exception that di-
	       rectories copied	by the option are created  with	 read,	write,
	       and  search  permission	for the	owner.	User and group permis-
	       sions remain unchanged.

	       With the	and options, in	addition to regular files and directo-
	       ries,  also  copies FIFOs, character and	block device files and
	       symbolic	links.	Only superusers	can copy  device  files.   All
	       other  users  get  an  error.  Symbolic links are copied	so the
	       target points to	the same location that the source did.

	       Warning:	 While copying a directory tree	that has  device  spe-
	       cial  files,  use  the option; otherwise, an infinite amount of
	       data is read from the device special file and is	duplicated  as
	       a  special  file	 in  the destination directory occupying large
	       file system space.

       Specifies the handling of any extent attributes of the file[s] to be
	       copied.	extarg takes one of the	following values.

		    Issues a warning message if	extent	attributes  cannot  be
		    copied,
			      but copies the file anyway.
		    Does not copy the extent attributes.
		    Fails  to copy the file if the extent attribute can	not be
		    copied.

	       Extent attributes can not be copied  if	the  files  are	 being
	       copied  to  a  file  system  which  does	not support extent at-
	       tributes	or if that file	system has a different block size than
	       the  original.	If is not specified, the default value for ex-
	       targ is

   Access Control Lists	(ACLs)
       If new_file is a	new file, or if	a new file is created  in  dest_direc-
       tory, it	inherits the access control list of the	original file1,	file2,
       etc., altered to	reflect	any difference in ownership  between  the  two
       files (see acl(5) and aclv(5)).	In JFS file systems, new files created
       by do not inherit their parent  directory's  default  ACL  entries  (if
       any),  but  instead  retain  the	 ACLs of the files being copied.  When
       copying files from a JFS	file system to an  HFS	file  system  or  vice
       versa, optional ACL entries are lost.

EXTERNAL INFLUENCES
   Environment Variables

       acters.

       and determine the local language	equivalent of y	(for yes/no queries).

       determines the language in which	messages are displayed.

       If is not specified in the environment or is set	to the	empty  string,
       the  value  of is used as a default for each unspecified	or empty vari-
       able.  If is not	specified or is	set to the empty string, a default  of
       "C"  (see lang(5)) is used instead of If	any internationalization vari-
       able contains an	invalid	setting, behaves as if	all  internationaliza-
       tion variables are set to "C".  See environ(5).

   International Code Set Support
       Single- and multi-byte character	code sets are supported.

EXAMPLES
       The following command moves the directory sourcedir and its contents to
       a new location (targetdir) in the file system.  Since creates  the  new
       directory,  the	destination directory targetdir	should not already ex-
       ist.

       The option copies the subtree (files and	subdirectories)	 in  directory
       sourcedir  to  directory	targetdir.  The	double ampersand (&&) causes a
       conditional action.  If the operation on	the left side  of  the	&&  is
       successful, the right side is executed (and removes the old directory).
       If the operation	on the left of the && is not successful, the  old  di-
       rectory is not removed.

       This example is equivalent to:

       To copy all files and directory subtrees	in the current directory to an
       existing	targetdir, use:

       To copy all files and directory subtrees	 in  sourcedir	to  targetdir,
       use:

       Note that directory pathnames can precede both sourcedir	and targetdir.

       To create a zero-length file, use any of	the following:
