CP

 

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

–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

-Z

set SELinux security context of destination file to default type

–context[=CTX]

like -Z, or if CTX is specified then set the SELinux or SMACK security context to CTX

–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.
