  37 .Sh NAME
  38 .Nm rcp
  39 .Nd remote file copy
  40 .Sh SYNOPSIS
  41 .Nm rcp
  42 .Op Fl Kpx
  43 .Op Fl k Ar realm
  44 .Ar file1 file2
  45 .Nm rcp
  46 .Op Fl Kprx

  48 .Ar file ...
  49 .Ar directory
  50 .Sh DESCRIPTION
  51 .Nm Rcp
  52 copies files between machines.  Each
  53 .Ar file
  54 or
  55 .Ar directory
  56 argument is either a remote file name of the
  57 form ``rname@rhost:path'', or a local file name (containing no `:' characters,
  58 or a `/' before any `:'s).
  59 .Pp
  60 .Bl -tag -width flag
  61 .It Fl K
  62 The
  63 .Fl K
  64 option turns off all Kerberos authentication.
  65 .It Fl k
  66 The
  67 .Fl k
  68 option requests
  69 .Nm rcp
  70 to obtain tickets
  71 for the remote host in realm
  72 .Ar realm
  73 instead of the remote host's realm as determined by
  74 .Xr krb_realmofhost  3  .
  75 .It Fl p
  76 The
  77 .Fl p
  78 option causes
  79 .Nm rcp
  80 to attempt to preserve (duplicate) in its copies the modification
  81 times and modes of the source files, ignoring the
  82 .Ar umask  .
  83 By default, the mode and owner of
  84 .Ar file2
  85 are preserved if it already existed; otherwise the mode of the source file
  86 modified by the
  87 .Xr umask  2
  88 on the destination host is used.
  89 .It Fl r
  90 If any of the source files are directories,
  91 .Nm rcp
  92 copies each subtree rooted at that name; in this case
  93 the destination must be a directory.
  94 .It Fl x
  95 The
  96 .Fl x
  97 option turns on
  98 .Tn DES
  99 encryption for all data passed by
 100 .Nm rcp .
 101 This may impact response time and
 102 .Tn CPU
 103 utilization, but provides
 104 increased security.
 105 .El
 106 .Pp
 107 If
 108 .Ar path
 109 is not a full path name, it is interpreted relative to
 110 the login directory of the specified user
 111 .Ar ruser
 112 on
 113 .Ar rhost  ,
 114 or your current user name if no other remote user name is specified.
 115 A
 116 .Ar path
 117 on a remote host may be quoted (using \e, ", or \(aa)
 118 so that the metacharacters are interpreted remotely.
 119 .Pp
 120 .Nm Rcp
 121 does not prompt for passwords; it performs remote execution
 122 via
 123 .Xr rsh  1  ,
 124 and requires the same authorization.
 125 .Pp
 126 .Nm Rcp
 127 handles third party copies, where neither source nor target files
 128 are on the current machine.

 131 .Xr ftp 1 ,

 133 .Xr rlogin 1
 134 .Sh HISTORY
 135 The
 136 .Nm rcp
 137 command appeared in
 138 .Bx 4.2 .
 139 The version of
 140 .Nm rcp
 141 described here
 142 has been reimplemented with Kerberos in
 143 .Bx 4.3 Reno .
 144 .Sh BUGS
 145 Doesn't detect all cases where the target of a copy might
 146 be a file in cases where only a directory should be legal.
 147 .Pp
 148 Is confused by any output generated by commands in a
 149 .Pa \&.login ,
 150 .Pa \&.profile ,
 151 or
 152 .Pa \&.cshrc
 153 file on the remote host.
 154 .Pp
 155 The destination user and hostname may have to be specified as
 156 ``rhost.rname'' when the destination machine is running the
 157 .Bx 4.2
 158 version of
 159 .Nm rcp  .
