Remote Copy – move files between machines.
Each file or directory is either a remote filename of the form rname@rhost:path or a local filename.
rcp [options] file1 file2
rcp [options] file ... directory
-k Attempt to get tickets for remote host; query krb_realmofhost to determine realm.
-p Preserve modification times and modes of the source files.
-r If any of the source files are directories, rcp copies each subtree rooted at that name.
The destination must be a directory.
-x Turns on DES encryption for all data passed by rcp.
