Damien Miller22c77262000-04-13 12:26:34 +100044.Sh DESCRIPTION
Damien Miller32aa1441999-10-29 09:15:49 +100045.Nm
Damien Miller450a7a12000-03-26 13:04:51 +100046copies files between hosts on a network.
47It uses
Damien Miller32aa1441999-10-29 09:15:49 +100048.Xr ssh 1
49for data transfer, and uses the same authentication and provides the
50same security as
51.Xr ssh 1 .
Damien Miller32aa1441999-10-29 09:15:49 +100052.Nm
53will ask for passwords or passphrases if they are needed for
54authentication.
55.Pp
Damien Millerb508faa2008-02-10 22:28:45 +110056File names may contain a user and host specification to indicate
Damien Miller450a7a12000-03-26 13:04:51 +100057that the file is to be copied to/from that host.
Damien Millerb508faa2008-02-10 22:28:45 +110058Local file names can be made explicit using absolute or relative pathnames
59to avoid
60.Nm
61treating file names containing
62.Sq :\&
63as host specifiers.
64Copies between two remote hosts are also permitted.
Damien Miller32aa1441999-10-29 09:15:49 +100065.Pp
66The options are as follows:
67.Bl -tag -width Ds

Damien Millerf1211432011-01-06 22:40:30 +110076.It Fl 3
77Copies between two remote hosts are transferred through the local host.
78Without this option the data is copied directly between the two remote
79hosts.
Damien Miller907998d2011-01-06 22:41:21 +110080Note that this option disables the progress meter.

Darren Tucker1f203942003-10-15 15:50:42 +100089.It Fl B
90Selects batch mode (prevents asking for passwords or passphrases).
91.It Fl C
92Compression enable.
93Passes the
94.Fl C
95flag to
96.Xr ssh 1
97to enable compression.
98.It Fl c Ar cipher
99Selects the cipher to use for encrypting the data transfer.
100This option is directly passed to
101.Xr ssh 1 .
102.It Fl F Ar ssh_config
103Specifies an alternative
104per-user configuration file for
105.Nm ssh .
106This option is directly passed to
107.Xr ssh 1 .
108.It Fl i Ar identity_file
Damien Millera034baf2008-07-12 17:12:49 +1000109Selects the file from which the identity (private key) for public key
Darren Tucker1f203942003-10-15 15:50:42 +1000110authentication is read.
111This option is directly passed to
112.Xr ssh 1 .
113.It Fl l Ar limit
114Limits the used bandwidth, specified in Kbit/s.
115.It Fl o Ar ssh_option
116Can be used to pass options to
117.Nm ssh
118in the format used in
119.Xr ssh_config 5 .
120This is useful for specifying options
121for which there is no separate
122.Nm scp
123command-line flag.
