NAME
cp - copy files and directories
SYNOPSIS
cp [OPTION]... [-T] SOURCE DEST
cp [OPTION]... SOURCE... DIRECTORY
cp [OPTION]... -t DIRECTORY SOURCE...
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
--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 (redundant if the -n option is
used)
-i, --interactive prompt
before overwrite (overrides a previous -n option)
-H
follow
command-line symbolic links in SOURCE
-l, --link 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
-c
same
as --preserve=context
--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
-Z, --context=CONTEXT set
security context of copy to CONTEXT --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, 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.
