Comando cp

< volver
Usage: cp [OPTION]... [-T] SOURCE DEST
 or: cp [OPTION]... SOURCE... DIRECTORY
 or: cp [OPTION]... -t DIRECTORY SOURCE...
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.
