.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 b Ar batchfile
will abort if any of the following
commands fail:
.Ic get , put , rename , ln ,
-.Ic rm , mkdir , chdir , lchdir
+.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 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
-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
+on the remote host.
+A path is useful for using
+.Nm
+over protocol version 1, or when the remote

does not have an sftp subsystem configured.

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.
