CP(1) FreeBSD General Commands Manual CP(1)
NAME
cp - copy files
SYNOPSIS
cp [-R [-H | -L | -P]] [-f | -i | -n] [-alNpsvx] source_file target_file
cp [-R [-H | -L | -P]] [-f | -i | -n] [-alNpsvx]
source_file ... target_directory
cp [-f | -i | -n] [-alNPpsvx] source_file target_file
cp [-f | -i | -n] [-alNPpsvx] source_file ... target_directory
DESCRIPTION
In the first synopsis form, the cp utility copies the contents of the
source_file to the target_file. In the second synopsis form, the
contents of each named source_file is copied to the destination
target_directory. The names of the files themselves are not changed. If
cp detects an attempt to copy a file to itself, the copy will fail.
The following options are available:
-H If the -R option is specified, symbolic links on the command line
are followed. (Symbolic links encountered in the tree traversal
are not followed.)
-L, --dereference
If the -R option is specified, all symbolic links are followed.
-P, --no-dereference
No symbolic links are followed. This is the default if the -R
option is specified.
-R, --recursive
If source_file designates a directory, cp copies the directory and
the entire subtree connected at that point. If the source_file
ends in a /, the contents of the directory are copied rather than
the directory itself. This option also causes symbolic links to be
copied, rather than indirected through, and for cp to create
special files rather than copying them as normal files. Created
directories have the same mode as the corresponding source
directory, unmodified by the process' umask.
Note that cp copies hard linked files as separate files. If you
need to preserve hard links, consider using tar(1), cpio(1), or
pax(1) instead.
-a, --archive
Archive mode. Same as -RpP.
-f, --force
For each existing destination pathname, remove it and create a new
file, without prompting for confirmation regardless of its
permissions. (The -f option overrides any previous -i or -n
options.)
-i, --interactive
Write a prompt to the standard error output before copying a file
that would overwrite an existing file. If the response from the
standard input begins with the character `y' or `Y', the file copy
is attempted. (The -i option overrides any previous -f or -n
options.)
-l, --link
Create hard links to regular files in a hierarchy instead of
copying.
-N When used with -p, suppress copying file flags.
-n, --no-clobber
Do not overwrite an existing file. (The -n option overrides any
previous -f or -i options.)
-p Preserve the following attributes of each source file in the copy:
modification time, access time, file flags, file mode, ACL, user
ID, and group ID, as allowed by permissions.
If the user ID and group ID cannot be preserved, no error message
is displayed and the exit value is not altered.
If the source file has its set-user-ID bit on and the user ID
cannot be preserved, the set-user-ID bit is not preserved in the
copy's permissions. If the source file has its set-group-ID bit on
and the group ID cannot be preserved, the set-group-ID bit is not
preserved in the copy's permissions. If the source file has both
its set-user-ID and set-group-ID bits on, and either the user ID or
group ID cannot be preserved, neither the set-user-ID nor set-
group-ID bits are preserved in the copy's permissions.
--sort
Visit and traverse sources in (non-localized) lexicographical
order. Normally, cp visits the sources in the order they were
listed on the command line, and if recursing, traverses their
contents in whichever order they were returned in by the kernel,
which may be the order in which they were created, lexicographical
order, or something else entirely. With --sort, the sources are
both visited and traversed in lexicographical order. This is
mostly useful for testing.
-s, --symbolic-link
Create symbolic links to regular files in a hierarchy instead of
copying.
-v, --verbose
Be verbose, showing both the source and destination path of each
file as is copied.
-x, --one-file-system
Do not traverse file system mount points.
For each destination file that already exists, its contents are
overwritten if permissions allow. Its mode, user ID, and group ID are
unchanged unless the -p option was specified.
In the second synopsis form, target_directory must exist unless there is
only one named source_file which is a directory and the -R flag is
specified.
If the destination file does not exist, the mode of the source file is
used as modified by the file mode creation mask (umask, see csh(1)). If
the source file has its set-user-ID bit on, that bit is removed unless
both the source file and the destination file are owned by the same user.
If the source file has its set-group-ID bit on, that bit is removed
unless both the source file and the destination file are in the same
group and the user is a member of that group. If both the set-user-ID
and set-group-ID bits are set, all of the above conditions must be
fulfilled or both bits are removed.
Appropriate permissions are required for file creation or overwriting.
Symbolic links are always followed unless the -R flag is set, in which
case symbolic links are not followed, by default. The -H or -L flags (in
conjunction with the -R flag) cause symbolic links to be followed as
described above. The -H, -L and -P options are ignored unless the -R
option is specified. In addition, these options override each other and
the command's actions are determined by the last one specified.
If cp receives a SIGINFO (see the status argument for stty(1)) signal,
the current input and output file and the percentage complete will be
written to the standard output.
EXIT STATUS
The cp utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
Make a copy of file foo named bar:
$ cp foo bar
Copy a group of files to the /tmp directory:
$ cp *.txt /tmp
Copy the directory junk and all of its contents (including any
subdirectories) to the /tmp directory:
$ cp -R junk /tmp
COMPATIBILITY
Historic versions of the cp utility had a -r option. This implementation
supports that option, however, its behavior is different from historical
FreeBSD behavior. Use of this option is strongly discouraged as the
behavior is implementation-dependent. In FreeBSD, -r is a synonym for
-RL and works the same unless modified by other flags. Historical
implementations of -r differ as they copy special files as normal files
while recreating a hierarchy.
The -a, -l, -N, -n, -s, -v, and -x options are non-standard and their use
in scripts is not recommended.

STANDARDS
The cp command is expected to be IEEE Std 1003.2 ("POSIX.2") compatible.

A cp command appeared in Version 1 AT&T UNIX.
