12 rcp: Copy files between machines

rcp copies files between machines. Each file or directory argument is either a remote file name of the form ‘rname@rhost:path’, or a local file name (containing no ‘:’ characters, or a ‘/’ before any ‘:’s).

     rcp [option]... old-file new-file
     rcp [option]... files... directory
-K
--kerberos
Turns off all Kerberos authentication.
-k
--realm=realm
The option requests rcp to obtain tickets for the remote host in realm realm instead of the remote host's realm.
-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 file are preserved if it already existed; otherwise the mode of the source file modified by the umask function on the destination host is used.
-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.
-x
--encrypt
Turns on DES 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.
