.Sh DESCRIPTION
|
|
.Nm
|
|
copies files between hosts on a network.
|
|
It uses
|
|
.Xr ssh 1
|
|
for data transfer, and uses the same authentication and provides the
|
|
same security as
|
|
.Xr ssh 1 .
|
|
Unlike
|
|
.Xr rcp 1 ,
|
|
.Nm
|
|
will ask for passwords or passphrases if they are needed for
|
|
authentication.
|
|
.Pp
|
|
File names may contain a user and host specification to indicate
|
|
that the file is to be copied to/from that host.
|
|
Local file names can be made explicit using absolute or relative pathnames
|
|
to avoid
|
|
.Nm
|
|
treating file names containing
|
|
.Sq :\&
|
|
as host specifiers.
|
|
Copies between two remote hosts are also permitted.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl 1
|
|
Forces
|
|
.Nm
|
|
to use protocol 1.
|
|
.It Fl 2
|
|
Forces
|
|
.Nm
|
|
to use protocol 2.
|
|
.It Fl 4
|
|
Forces
|
|
.Nm
|
|
to use IPv4 addresses only.
|
|
.It Fl 6
|
|
Forces
|
|
.Nm
|
|
to use IPv6 addresses only.
|
|
.It Fl B
|
|
Selects batch mode (prevents asking for passwords or passphrases).
|
|
.It Fl C
|
|
Compression enable.
|
|
Passes the
|
|
.Fl C
|
|
flag to
|
|
.Xr ssh 1
|
|
to enable compression.
|
|
.It Fl c Ar cipher
|
|
Selects the cipher to use for encrypting the data transfer.
|
|
This option is directly passed to
|
|
.Xr ssh 1 .
|
|
.It Fl F Ar ssh_config
|
|
Specifies an alternative
|
|
per-user configuration file for
|
|
.Nm ssh .
|
|
This option is directly passed to
|
|
.Xr ssh 1 .
|
|
.It Fl i Ar identity_file
|
|
Selects the file from which the identity (private key) for public key
|
|
authentication is read.
|
|
This option is directly passed to
|
|
.Xr ssh 1 .
|
|
.It Fl l Ar limit
|
|
Limits the used bandwidth, specified in Kbit/s.
|
|
.It Fl o Ar ssh_option
|
|
Can be used to pass options to
|
|
.Nm ssh
|
|
in the format used in
|
|
.Xr ssh_config 5 .
|
|
This is useful for specifying options
|
|
for which there is no separate
|
|
.Nm scp
|
|
command-line flag.
|
|

.It Fl P Ar port
|
|
Specifies the port to connect to on the remote host.
|
|
Note that this option is written with a capital
|
|
.Sq P ,
|
|
because
|
|
.Fl p
|
|
is already reserved for preserving the times and modes of the file in
|
|
.Xr rcp 1 .
|
|
.It Fl p
|
|
Preserves modification times, access times, and modes from the
|
|
original file.
|
|
.It Fl q
|
|
Quiet mode: disables the progress meter as well as warning and diagnostic
|
|
messages from
|
|
.Xr ssh 1 .
|
|
.It Fl r
|
|
Recursively copy entire directories.
|
|
Note that
|
|
.Nm
|
|
follows symbolic links encountered in the tree traversal.
|
|
.It Fl S Ar program
|
|
Name of
|
|
.Ar program
|
|
to use for the encrypted connection.
|
|
The program must understand
|
|
.Xr ssh 1
|
|
options.
|
|
.It Fl v
|
|
Verbose mode.
|
|
Causes
|
|
.Nm
|
|
and
|
|
.Xr ssh 1
|
|
to print debugging messages about their progress.
|
|
This is helpful in
|
|
debugging connection, authentication, and configuration problems.
