39 | .Sh DESCRIPTION | |
40 | .Nm | |
41 | copies files between hosts on a network. It uses | |
42 | .Xr ssh 1 | |
43 | for data transfer, and uses the same authentication and provides the | |
44 | same security as | |
45 | .Xr ssh 1 . | |
46 | Unlike | |
47 | .Xr rcp 1 , | |
48 | .Nm | |
49 | will ask for passwords or passphrases if they are needed for | |
50 | authentication. | |
51 | .Pp | |
52 | Any file name may contain a host and user specification to indicate | |
53 | that the file is to be copied to/from that host. Copies between two | |
54 | remote hosts are permitted. | |
55 | .Pp | |
56 | The options are as follows: | |
57 | .Bl -tag -width Ds | |
58 | .It Fl c Ar cipher | |
59 | Selects the cipher to use for encrypting the data transfer. This | |
60 | option is directly passed to | |
61 | .Xr ssh 1 . | |
62 | .It Fl i Ar identity_file | |
63 | Selects the file from which the identity (private key) for RSA | |
64 | authentication is read. This option is directly passed to | |
65 | .Xr ssh 1 . | |
66 | .It Fl p | |
67 | Preserves modification times, access times, and modes from the | |
68 | original file. | |
69 | .It Fl r | |
70 | Recursively copy entire directories. | |
71 | .It Fl v | |
72 | Verbose mode. Causes | |
73 | .Nm | |
74 | and | |
75 | .Xr ssh 1 | |
76 | to print debugging messages about their progress. This is helpful in | |
77 | debugging connection, authentication, and configuration problems. | |
78 | .It Fl B | |
79 | Selects batch mode (prevents asking for passwords or passphrases). | |
80 | .It Fl q | |
81 | Disables the progress meter. | |
82 | .It Fl C | |
83 | Compression enable. Passes the | |
84 | .Fl C | |
85 | flag to | |
86 | .Xr ssh 1 | |
87 | to enable compression. | |
88 | .It Fl P Ar port | |
89 | Specifies the port to connect to on the remote host. Note that this | |
90 | option is written with a capital | |
91 | .Sq P , | |
92 | because | |
93 | .Fl p | |
94 | is already reserved for preserving the times and modes of the file in | |
95 | .Xr rcp 1 . | |

103 | California. | |
