It uses 42.Xr ssh 1 43for data transfer, and uses the same authentication and provides the 44same security as 45.Xr ssh 1 . 46Unlike 47.Xr rcp 1 , 48.Nm 49will ask for passwords or passphrases if they are needed for 50authentication. 51.Pp 52Any file name may contain a host and user specification to indicate 53that the file is to be copied to/from that host. Copies between two 54remote hosts are permitted. 55.Pp 56The options are as follows: 57.Bl -tag -width Ds 58.It Fl c Ar cipher 59Selects the cipher to use for encrypting the data transfer. This 60option is directly passed to 61.Xr ssh 1 . 62.It Fl i Ar identity_file 63Selects the file from which the identity (private key) for RSA 64authentication is read. This option is directly passed to 65.Xr ssh 1 . 66.It Fl p 67Preserves modification times, access times, and modes from the 68original file. 69.It Fl r 70Recursively copy entire directories. 71.It Fl v 72Verbose mode. Causes 73.Nm 74and 75.Xr ssh 1 76to print debugging messages about their progress. This is helpful in 77debugging connection, authentication, and configuration problems. 78.It Fl B 79Selects batch mode (prevents asking for passwords or passphrases). 80.It Fl q 81Disables the progress meter. 82.It Fl C 83Compression enable. Passes the 84.Fl C 85flag to 86.Xr ssh 1 87to enable compression. 88.It Fl P Ar port 89Specifies the port to connect to on the remote host. Note that this 90option is written with a capital 91.Sq P , 92because 93.Fl p 94is already reserved for preserving the times and modes of the file in 95.Xr rcp 1 . 96.It Fl 4 97Forces 98.Nm 99to use IPv4 addresses only. 100.It Fl 6 101Forces 102.Nm 103to use IPv6 addresses only. 104.Sh AUTHORS 105Timo Rinne <tri@iki.fi> and Tatu Ylonen <ylo@cs.hut.fi> 106.Sh HISTORY 107.Nm 108is based on the 109.Xr rcp 1 110program in BSD source code from the Regents of the University of 111California. 112.Sh SEE ALSO 113.Xr rcp 1 , 114.Xr ssh 1 , 115.Xr ssh-add 1 , 116.Xr ssh-agent 1 , 117.Xr ssh-keygen 1 , 118.Xr sshd 8 119
