and uses the same authentication and provides the +same security as +.Xr ssh 1 . +.Nm +will ask for passwords or passphrases if they are needed for +authentication. +.Pp +The +.Ar source +and +.Ar target +may be specified as a local pathname, a remote host with optional path +in the form +.Sm off +.Oo user @ Oc host : Op path , +.Sm on +or a URI in the form +.Sm off +.No scp:// Oo user @ Oc host Oo : port Oc Op / path . +.Sm on +Local file names can be made explicit using absolute or relative pathnames +to avoid +.Nm +treating file names containing +.Sq :\& +as host specifiers. +.Pp +When copying between two remote hosts, if the URI format is used, a +.Ar port +may only be specified on the +.Ar target +if the +.Fl 3 +option is used. +.Pp +The options are as follows: +.Bl -tag -width Ds +.It Fl 3 +Copies between two remote hosts are transferred through the local host. +Without this option the data is copied directly between the two remote +hosts. +Note that this option disables the progress meter and selects batch mode +for the second host, since +.Nm +cannot ask for passwords or passphrases for both hosts. +.It Fl 4 +Forces +.Nm +to use IPv4 addresses only. +.It Fl 6 +Forces +.Nm +to use IPv6 addresses only. +.It Fl A +Allows forwarding of +.Xr ssh-agent 1 +to the remote system. +The default is not to forward an authentication agent. +.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 J Ar destination +Connect to the target host by first making an +.Nm +connection to the jump host described by +.Ar destination +and then establishing a TCP forwarding to the ultimate destination from +there. +Multiple jump hops may be specified separated by comma characters. +This is a shortcut to specify a +.Cm ProxyJump +configuration directive. +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

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 T +Disable strict filename checking. +By default when copying files from a remote host to a local directory +.Nm +checks that the received filenames match those requested on the command-line +to prevent the remote end from sending unexpected or unwanted files. +Because of differences in how various operating systems and shells interpret +filename wildcards, these checks may cause wanted files to be rejected. +This option disables these checks at the expense of fully trusting that +the server will not send unexpected filenames. +.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. +.El +.Sh
