CP (1)
NAME
cp - copy files
SYNOPSIS
cp [ Rfhip ] source_file target_file cp [ Rfhip ] 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 it-
self, the copy will fail.
The following options are available:
R - If source_file designates a directory, cp copies the
directory and the entire subtree connected at that point.
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 direc-
tories have the same mode as the corresponding source direc-
tory, unmodified by the process' umask.
f - For each existing destination pathname, remove it and
create a new file, without prompting for confirmation re-
gardless of its permissions. (The option is ignored if the
option is specified.)
h - Forces cp to follow symbolic links. Provided for the
option which does not follow symbolic links by default.
i - Causes cp to write a prompt to standard error before
copying a file that would overwrite an existing file. If
the response from the standard input begins with the charac-
ter the file is copied if permissions allow the copy.
p - Causes cp to preserve in the copy as many of the modifi-
cation time, access time, file mode, 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 the 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 or set group ID bits are
preserved in the copy's permissions.
For each destination file that already exists, its contents are
overwritten if permissions allow, but its mode, user ID, and
group ID are unchanged.
If the destination file does not exist, the mode of the source
file is used as modified by the file mode creation mask 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 followed unless the option is specified, in
which case the link itself is copied.
Cp exits 0 on success, >0 if an error occurred.

HISTORY
The cp command is expected to be compatible.
