.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 fetch files automaticly if a non-interactive
-authentication is used, else it do so after an interactive authentication
-is used.
+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.
+The third usage format allows
+.Nm
+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 necessary to configure non-interactive 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 2
+Specify the use of protocol version 2.
+.It Fl 4
+Forces
+.Nm
+to use IPv4 addresses only.
+.It Fl 6
+Forces
+.Nm
+to use IPv6 addresses only.
+.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
+will abort if any of the following
+commands fail:
+.Ic get , put , rename , ln ,
+.Ic rm , mkdir , chdir , ls ,
+.Ic lchdir , chmod , chown ,
+.Ic chgrp , lpwd , df ,
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 Ar cipher
+Selects the cipher to use for encrypting the data transfers.
+This option is directly passed to
+.Xr ssh 1 .
+.It Fl D 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 F Ar ssh_config
+Specifies an alternative
+per-user configuration file for
+.Xr ssh 1 .
+This option is directly passed to
+.Xr ssh 1 .
+.It Fl i Ar identity_file
+Selects the file from which the identity (private key) for public key
+authentication is read.
+This option is directly passed to
+.Xr ssh 1 .
.It Fl o Ar ssh_option
-Specify an option to be directly passed to
+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 .
+For full details of the options listed below, and their possible values, see
+.Xr ssh_config 5 .

+Preserves modification times, access times, and modes from the

+.It Fl q
+Quiet mode: disables the progress meter as well as warning and
+diagnostic messages from
.Xr ssh 1 .
+.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 64 outstanding requests.
+.It Fl r
+Recursively copy entire directories when uploading and downloading.
+Note that
+.Nm
+does not follow symbolic links encountered in the tree traversal.
+.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 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

+over protocol version 1, or when the remote
+.Xr sshd 8
+does not have an sftp subsystem configured.
