DESCRIPTION

The

rcp command copies ﬁles, directory subtrees, or a combination of ﬁles and directory subtrees from

one or more systems to another. In many respects, it is similar to the cp command (see cp(1)).

To use

rcp, you must have read access to ﬁles being copied, and read and search (execute) permission on

all directories in the directory path. Note that there are special requirements for third-party transfers,

which are described in the Third-Party Transfers section below.

In a Kerberos V5 Network Authentication environment,

rcp uses the Kerberos V5 protocol while initiat-

ing the connection to a remote host. The authorization mechanism is dependent on the command line

options used to invoke

remshd on the remote host (i.e., -K, -R, -r,or

-k). Kerberos authentication

and authorization rules are described in the Secure Internet Services man page, sis (5).

Although Kerberos authentication and authorizations may apply, the Kerberos mechanism is not applied

when copying ﬁles. The ﬁles are still transferred in clear text over the network.

The

fallback option can be set in the krb5.conf ﬁle within appdefaults Section . Refer to the

krb5.conf (4) manpage for more information on the appdefaults Section .Iffallback is set to true and

the kerberos authentication fails, rcp will use the non-secure mode of authentication.

Note: Command line options override the conﬁguration ﬁle options.

Options and Arguments

rcp recognizes the following options and arguments:

source_file , source_dir

This option speciﬁes the name of an existing ﬁle or directory on a local or remote

machine that you want to be copied to a speciﬁed destination. The source ﬁle and

directory names are constructed as follows:

user_name

@hostname :pathname /ﬁlename

user_name

@hostname :pathname /dirname

Component parts of ﬁle and directory names are described below. If multiple exist-

ing ﬁles and/or directory subtrees (source_ﬁle1, source_ﬁle2, ..., etc.) are speciﬁed,

then the destination must be a directory. Shell ﬁle name expansion is allowed on

rcp(1) rcp(1) both local and remote systems. Multiple files and directory subtrees can be copied from one or more systems to a single destination directory by using a single command. dest_file This option specifies the name of the destination file. If host name and path name are not specified, then the existing file is copied into a file named dest_file in the current directory on the local system. If dest_file already exists and is writable, then the existing file is overwritten.
PAGE 3
rcp(1) rcp(1) hostname Hostname of remote system where directories and files are located. pathname Absolute directory path name or directory path name relative to the login directory of user user_name . filename Actual name of source or destination file. File name expansion is allowed on source file names. dirname Actual name of source or destination directory subtree. File name expansion is allowed on source directory names.
PAGE 4
rcp(1) rcp(1) will certainly fail on one of the source systems. Perform such a transfer using two separate commands. With the existing implementation of rcp, the remote copy may result in a system overwrite as described in the following example. rcp -r path root@hostname: / In this example, if you run rcp as root, and unintentionally type a space between the colon (:) and the slash (/), then rcp assumes both path and root@hostname: (the remote machine’s root directory) as source.
