39.Sh NAME
40.Nm rcp
41.Nd remote file copy
42.Sh SYNOPSIS
43.Nm
44.Op Fl Kpx
45.Op Fl k Ar realm
46.Ar file1 file2
47.Nm ""
48.Op Fl Kprx
49.Op Fl k Ar realm
50.Ar file ...
51.Ar directory
52.Sh DESCRIPTION
53.Nm
54copies files between machines.
55Each
56.Ar file
57or
58.Ar directory
59argument is either a remote file name of the
60form ``rname@rhost:path'', or a local file name (containing no `:' characters,
61or a `/' before any `:'s).
62.Pp
63.Bl -tag -width flag
64.It Fl K
65The
66.Fl K
67option turns off all Kerberos authentication.
68.It Fl k
69The
70.Fl k
71option requests
72.Nm
73to obtain tickets
74for the remote host in realm
75.Ar realm
76instead of the remote host's realm as determined by
77.Xr krb_realmofhost  3  .
78.It Fl p
79The
80.Fl p
81option causes
82.Nm
83to attempt to preserve (duplicate) in its copies the modification
84times and modes of the source files, ignoring the
85.Ar umask  .
86By default, the mode and owner of
87.Ar file2
88are preserved if it already existed; otherwise the mode of the source file
89modified by the
90.Xr umask  2
91on the destination host is used.
92.It Fl r
93If any of the source files are directories,
94.Nm
95copies each subtree rooted at that name; in this case
96the destination must be a directory.
97.It Fl x
98The
99.Fl x
100option turns on
101.Tn DES
102encryption for all data passed by
103.Nm "" .
104This may impact response time and
105.Tn CPU
106utilization, but provides
107increased security.
108.El
109.Pp
110If
111.Ar path
112is not a full path name, it is interpreted relative to
113the login directory of the specified user
114.Ar ruser
115on
116.Ar rhost  ,
117or your current user name if no other remote user name is specified.
118A
119.Ar path
120on a remote host may be quoted (using \e, ", or \(aa)
121so that the metacharacters are interpreted remotely.
122.Pp
123.Nm
124does not prompt for passwords; it performs remote execution
125via
126.Xr rsh  1  ,
127and requires the same authorization.
128.Pp
129.Nm
130handles third party copies, where neither source nor target files
131are on the current machine.
132.Sh SEE ALSO
133.Xr cp 1 ,

138.Xr rhosts 5
139.Sh HISTORY
140The
141.Nm
142utility appeared in
143.Bx 4.2 .
144The version of
145.Nm
146described here
147has been reimplemented with Kerberos in
148.Bx 4.3 Reno .
149.Sh BUGS
150Doesn't detect all cases where the target of a copy might
151be a file in cases where only a directory should be legal.
152.Pp
153Is confused by any output generated by commands in a
154.Pa \&.login ,
155.Pa \&.profile ,
156or
157.Pa \&.cshrc
158file on the remote host.
159.Pp
160The destination user and hostname may have to be specified as
161``rhost.rname'' when the destination machine is running the
162.Bx 4.2
163version of
164.Nm "" .
