.Sh DESCRIPTION
.Nm
is an interactive file transfer program, similar to
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.
+The third usage format allows the sftp client to start in a remote directory.
.Pp
+The final usage format allows for automated sessions using the
+.Fl b
+option.
+In such cases, it is usually necessary to configure public key authentication
+to obviate the need to enter a password at connection time (see
+.Xr sshd 8
+and
+.Xr ssh-keygen 1
+for details).
The options are as follows:
.Bl -tag -width Ds
.It Fl 1
Specify the use of protocol version 1.
+.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 b Ar batchfile
Batch mode reads a series of commands from an input
.Ar batchfile
.Em stdin .
Since it lacks user interaction it should be used in conjunction with
non-interactive authentication.
+A
+.Ar batchfile
+of
+.Sq \-
+may be used to indicate standard input.
.Nm
will abort if any of the following
commands fail:
-.Ic get , put , rename , ln , rm , mkdir , chdir , lchdir
+.Ic get , put , rename , ln ,
+.Ic rm , mkdir , chdir , ls ,
+.Ic lchdir , chmod , chown , chgrp , lpwd
and
.Ic lmkdir .
+Termination on error can be suppressed on a command by command basis by
+prefixing the command with a
+.Sq \-
+character (for example,
+.Ic -rm /tmp/blah* ) .
.It Fl C
Enables compression (via ssh's
.Fl C
.It Fl F Ar ssh_config
Specifies an alternative
per-user configuration file for
-.Nm ssh .
+.Xr ssh 1 .
This option is directly passed to
.Xr ssh 1 .
.It Fl o Ar ssh_option
Can be used to pass options to
.Nm ssh
-in the format used in the
-.Xr ssh 1
-configuration file. This is useful for specifying options
+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:
+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.
+For full details of the options listed below, and their possible values, see
+.Xr ssh_config 5 .

+.El
+.It Fl P Ar sftp_server_path
+Connect directly to a local sftp server
+(rather than via
+.Xr ssh 1 )
+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
The program must understand
.Xr ssh 1
options.
+.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
+.Nm
+over protocol version 1, or when the remote
+.Xr sshd 8
+does not have an sftp subsystem configured.
.It Fl v
-Raise logging level. This option is also passed to ssh.
