12.1 Command line options

-4 ¶

--ipv4

Use only IPv4.

-6 ¶

--ipv6

Use only IPv6.

-d directory ¶

--target-directory=directory

Copy all source arguments into directory.

-f ¶

--from

(Server mode only.) Copying from remote host.

-k realm ¶

--realm=realm

The option requests rcp to obtain tickets for the remote host in realm realm instead of the remote host’s realm.

-K ¶

--kerberos

Turns off all Kerberos authentication.

-p ¶

--preserve

Causes rcp to attempt to preserve (duplicate) in its copies the modification times and modes of the source files, ignoring the umask. By default, the mode and owner of the target file are preserved if the target itself already exists; otherwise the mode of the source file is modified by the umask setting on the destination host.

-r ¶

--recursive

If any of the source files are directories, rcp copies each subtree rooted at that name; in this case the destination must be a directory.

-t ¶

--to

(Server mode only.) Copying to remote host.

-x ¶

--encrypt

Turns on encryption for all data passed via the rcp session. This may impact response time and CPU utilization, but provides increased security.

rcp doesn’t detect all cases where the target of a copy might be a file in cases where only a directory should be legal.

rcp can be confused by any output generated by commands in a .login, .profile, or .cshrc file on the remote host.

The destination user and hostname may have to be specified as ‘rhost.rname’ when the destination machine is running the 4.2BSD version of rcp.
