.Nm
is an interactive file transfer program, similar to

+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 lmkdir .
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
-.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

-.Nm

This option may be useful in debugging the client and server.
