.Sh DESCRIPTION
.Nm
is an interactive file transfer program, similar to
compression.
.Nm
connects and logs into the specified
-.Ar hostname ,
+.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
-.Fn batchfile
+.Ar batchfile
instead of
-.Fn stdin .
-Since it lacks user interaction it should be used in conjuction with a
-non-interactive authentication. Sftp will abort if any of the following
-commands fail:
-.Pa get, put, rename, ln, rm, mkdir, chdir, lchdir
+.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 , rm , mkdir , chdir , lchdir
and
-.Pa lmkdir.
-.It Fl C
-Enables compression (via ssh's
-.Fl C
-flag)
+.Ic lmkdir .
.It Fl o Ar ssh_option
-Specify an option to be directly passed to
-.Xr ssh 1 .
+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
+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 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.
