Remote file copy
Syntax:
rcp [-p] source_file target_file
rcp [-p] [-r] source_file... target_dir
Options:
- -p
- Attempt to preserve (duplicate) the modification time and file mode of each source file in its corresponding
target file, ignoring the
umask.
By default, the mode and owner of the target file are preserved if the target file already exists;
otherwise the mode of the source file modified by the umask on the destination host is used.
- -r
- If any of the source files are directories, copy each subtree rooted at that name;
in this case, the destination must be a directory.
- source_file
- The pathname of a file to be copied.
- target_file
- The pathname to which a single file is copied.
- target_dir
- The pathname of an existing directory that's to contain the output file(s).
Description:
The rcp utility copies files between machines.
Each file or directory argument is either of the following:
- a remote filename of the form rname@rhost:path
- a local filename that has no : characters, or that has a / before any :
If the specified path isn't a full pathname, it's
interpreted relative to the login directory of the specified
user ruser on rhost, or of your
current username if no other remote username
(rname) is specified. A path on a remote host may
be quoted (using \, ", or
') so that the metacharacters are interpreted remotely.
The rcp utility doesn't prompt for passwords; it
performs remote execution via rsh,
and requires the same authorization.
The rcp utility handles third-party copies, where neither
source nor target files are on the current machine.
Note:
This utility needs to have the setuid (
set user ID) bit set in its permissions.
If you use
mkefs,
mketfs,
mkifs,
mkmerklefs,
or
mkqnx6fs
on a Windows host to include this utility in an image,
use the
perms attribute to specify its permissions explicitly,
and the
uid and
gid attributes to set the ownership correctly.
Files:
The rcp utility requires the libsocket.so shared library.
Caveats:
The rcp utility doesn't always detect that the target of a copy
is a file in cases where only a directory should be legal.
It's also confused by any output generated by commands in a
.login or .profile file on the remote host.
