| .Nm sftp |
| .Op [\fIuser\fR@]\fIhost\fR[:\fIdir\fR[\fI/\fR]] |
| .Sh DESCRIPTION |
| .Nm |
| is an interactive file transfer program, similar to |
| .Xr ftp 1 , |
| which performs all operations over an encrypted |
| .Xr ssh 1 |
| transport. |
| It may also use many features of ssh, such as public key authentication and |
| compression. |
| .Nm |
| connects and logs into the specified |
| .Ar host , |
| then enters an interactive command mode. |
| .Pp |
| The second usage format will retrieve files automatically if a non-interactive |
| authentication method is used; otherwise it will do so after |
| successful interactive authentication. |
| .Pp |
| The last usage format allows the sftp client to start in a remote directory. |
| .Pp |
| The options are as follows: |
| .Bl -tag -width Ds |
| .It Fl b Ar batchfile |
| Batch mode reads a series of commands from an input |
| .Ar batchfile |
| instead of |
| .Em stdin . |
| Since it lacks user interaction it should be used in conjunction with |
| non-interactive authentication. |
| .Nm |
| will abort if any of the following |
| commands fail: |
| .Ic get , put , rename , ln , |
| .Ic rm , mkdir , chdir , lchdir |
| and |
| .Ic lmkdir . |
| .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 sftp |
| command-line flag. For example, to specify an alternate |
| port use: |
| .Ic sftp -oPort=24 . |
| .It Fl s Ar subsystem | sftp_server |
| Specifies the SSH2 subsystem or the path for an sftp server |
| on the remote host. A path is useful for using sftp over |
| protocol version 1, or when the remote |
| .Nm sshd |
| does not have an sftp subsystem configured. |
| .It Fl v |
| Raise logging level. This option is also passed to ssh. |
| .It Fl B Ar buffer_size |
| Specify the size of the buffer that |
| .Nm |
| uses when transferring files. Larger buffers require fewer round trips at |
| the cost of higher memory consumption. The default is 32768 bytes. |
| .It Fl C |
| Enables compression (via ssh's |
| .Fl C |
| flag). |
| .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 P Ar sftp_server path |
| Connect directly to a local |
| .Nm sftp-server |
| (rather than via |
| .Nm ssh ) |
| This option may be useful in debugging the client and server. |
| .It Fl R Ar num_requests |
| Specify how many requests may be outstanding at any one time. Increasing |
| this may slightly improve file transfer speed but will increase memory |
| usage. The default is 16 outstanding requests. |
| .It Fl S Ar program |
| Name of the |
| .Ar program |
| to use for the encrypted connection. |
| The program must understand |
| .Xr ssh 1 |
| options. |
| .It Fl 1 |
| Specify the use of protocol version 1. |
| .El |
| .Sh INTERACTIVE COMMANDS |
| Once in interactive mode, |
| .Nm |
| understands a set of commands similar to those of |
| .Xr ftp 1 . |
| Commands are case insensitive and pathnames may be enclosed in quotes if they |
| contain spaces. |
