| .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 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. |
| .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. |
| For full details of the options listed below, and their possible values, see |
| .Xr ssh_config 5 . |

| .El |
| .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. |
