DESCRIPTION

Copy SOURCE to DEST, or multiple SOURCE(s) to DIRECTORY.

Mandatory arguments to long options are mandatory for short options too.

−a, −−archive: same as −dR −−preserve=all
−−attributes−only: 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: copy contents of special files when recursive
−d: same as −−no−dereference −−preserve=links
−f, −−force: if an existing destination file cannot be opened, remove it and try again (this option is ignored when the −n option is also used)
−i, −−interactive: prompt before overwrite (overrides a previous −n option)
−H: follow command−line symbolic links in SOURCE
−l, −−link: hard link files instead of copying
−L, −−dereference: always follow symbolic links in SOURCE
−n, −−no−clobber: do not overwrite an existing file (overrides a previous −i option)
−P, −−no−dereference: never follow symbolic links in SOURCE
−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
−−no−preserve=ATTR_LIST: don't preserve the specified attributes
−−parents: use full source file name under DIRECTORY
−R, −r, −−recursive: copy directories recursively
−−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, −−symbolic−link: make symbolic links instead of copying
−S, −−suffix=SUFFIX: override the usual backup suffix
−t, −−target−directory=DIRECTORY: copy all SOURCE arguments into DIRECTORY
−T, −−no−target−directory: treat DEST as a normal file
−u, −−update: copy only when the SOURCE file is newer than the destination file or when the destination file is missing
−v, −−verbose: explain what is being done
−x, −−one−file−system: stay on this file system
−−help: display this help and exit
−−version: output version information and exit

By default, sparse SOURCE files are detected by a crude heuristic and the corresponding DEST file is made sparse as well. That is 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] is specified, perform a lightweight copy, where the data blocks are copied only when modified. If this is not possible the copy fails, or if −−reflink=auto is specified, fall back to a standard copy.

The backup suffix is '~', 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 are 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 make simple backups

As a special case, cp makes a backup of SOURCE when the force and backup options are given and SOURCE and DEST are the same name for an existing, regular file.
