Each.Ar fileor.Ar directoryargument is either a remote file name of theform ``rname@rhost:path'', or a local file name (containing no `:' characters,or a `/' before any `:'s)..Pp.Bl -tag -width flag.It Fl KThe.Fl Koption turns off all Kerberos authentication..It Fl kThe.Fl koption requests.Nm rcpto obtain ticketsfor the remote host in realm.Ar realminstead of the remote host's realm as determined by.Xr krb_realmofhost  3  ..It Fl pThe.Fl poption causes.Nm rcpto attempt to preserve (duplicate) in its copies the modificationtimes and modes of the source files, ignoring the.Ar umask  .By default, the mode and owner of.Ar file2are preserved if it already existed; otherwise the mode of the source filemodified by the.Xr umask  2on the destination host is used..It Fl rIf any of the source files are directories,.Nm rcpcopies each subtree rooted at that name; in this casethe destination must be a directory..It Fl xThe.Fl xoption turns on.Tn DESencryption for all data passed by.Nm rcp .This may impact response time and.Tn CPUutilization, but providesincreased security..El.PpIf.Ar pathis not a full path name, it is interpreted relative tothe login directory of the specified user.Ar ruseron.Ar rhost  ,or your current user name if no other remote user name is specified.A.Ar pathon a remote host may be quoted (using \e, ", or \(aa)so that the metacharacters are interpreted remotely..Pp.Nm Rcpdoes not prompt for passwords; it performs remote executionvia.Xr rsh  1  ,and requires the same authorization..Pp.Nm Rcphandles third party copies, where neither source nor target filesare on the current machine..Sh SEE ALSO.Xr cp 1 ,.Xr ftp 1 ,.Xr rsh 1 ,.Xr rlogin 1.Sh HISTORYThe.Nm rcpcommand appeared in.Bx 4.2 .The version of.Nm rcpdescribed herehas been reimplemented with Kerberos in.Bx 4.3 Reno ..Sh BUGSDoesn't detect all cases where the target of a copy mightbe a file in cases where only a directory should be legal..PpIs confused by any output generated by commands in a.Pa \&.login ,.Pa \&.profile ,or.Pa \&.cshrcfile on the remote host..PpThe destination user and hostname may have to be specified as``rhost.rname'' when the destination machine is running the.Bx 4.2version of.Nm rcp  .
