cp(1) General Commands Manual cp(1)Name
cp - copy file data
Syntax
cp [ -f ] [ -i ] [ -p ] file1 file2
cp [ -f ] [ -i ] [ -p ] [ -r ] file... directory
cp [ -f ] [ -i ] [ -p ] [ -r ] directory... directory
Description
The command copies file1 onto file2. The mode and owner of file2 are preserved if it already existed; the mode of file1 is used otherwise.
Note that the command will not copy a file onto itself.
In the second form, one or more files are copied into the directory with their original file names.
In the third form, one or more source directories are copied into the destination directory with their original file names.
Options-f Forces existing destination pathnames to be removed before copying, without prompting for confirmation. The -i option is ignored if
the -f option is specified.
-i Prompts user with the name of file whenever the copy will cause an old file to be overwritten. A yes answer will cause to continue.
Any other answer will prevent it from overwriting the file.
-p Preserves (duplicates) in the copies the modification time, access time, file mode, user ID, and group ID as allowed by the permis-
sions of the source files, ignoring the present umask.
-r Copies directories. Entire directory trees, including their subtrees and the individual files they contain, are copied to the speci-
fied destination directory. The directory, its subtrees, and the individual files retain their original names. For example, to copy
the directory including all of its subtrees and files, into the directory enter the following command:
cp -r reports news

rcp - remote file copy
SYNOPSIS
rcp [-p] file1 file2
rcp [-pr] file ... directory
DESCRIPTION
Rcp copies files between machines. Each file or directory argument is either a remote file name of the form ``rhost:path'', or a local
file name (containing no `:' characters, or a `/' before any `:'s).
If the -r option is specified and any of the source files are directories, rcp copies each subtree rooted at that name; in this case the
destination must be a directory.
By default, the mode and owner of file2 are preserved if it already existed; otherwise the mode of the source file modified by the umask(2)
on the destination host is used. The -p option causes rcp to attempt to preserve (duplicate) in its copies the modification times and
modes of the source files, ignoring the umask.
If path is not a full path name, it is interpreted relative to your login directory on rhost. A path on a remote host may be quoted (using
, ", or ') so that the metacharacters are interpreted remotely.
Rcp does not prompt for passwords; your current local user name must exist on rhost and allow remote command execution via rsh(1).
Rcp handles third party copies, where neither source nor target files are on the current machine. Hostnames may also take the form
``rname@rhost'' to use rname rather than the current user name on the remote host. The destination hostname may also take the form
``rhost.rname'' to support destination machines that are running 4.2BSD versions of rcp.
SEE ALSO cp(1), ftp(1), rsh(1), rlogin(1).
BUGS
Doesn't detect all cases where the target of a copy might be a file in cases where only a directory should be legal.
Is confused by any output generated by commands in a .profile, or .*shrc file on the remote host.
