.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 form 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 batchfile
Batch mode reads a series of commands from an input
.Ar batchfile
.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 .
-.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 .
+Termination on error can be suppressed on a command by command basis by
+prefixing the command with a
+.Ic '-'
+character (For example,
+.Ic -rm /tmp/blah*
+).
.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
+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
+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
The program must understand
.Xr ssh 1
options.
-.It Fl v
-Raise logging level. This option is also passed to ssh.
+.It Fl 1
+Specify the use of protocol version 1.
