+.Sh SYNOPSIS
+.Nm sftp
+.Op Fl v Li | Fl C
+.Op Fl o Ar ssh_option
+.Op Ar hostname | user@hostname
+.Sh DESCRIPTION
+.Nm
+is an interactive file transfer program, similar to
+.Xr ftp 1 ,
+which performs all operations over an encrypted
+.Xr ssh 1
+transport.
+It may also use many features of ssh, such as public key authentication and
+compression.
+.Nm
+connects and logs into the specified
+.Ar hostname
+then enters an interactive command mode.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl C
+Enables compression (via ssh's
+.Fl C
+flag)
+.It Fl v
+Raise logging level. This option is also passed to ssh.
+.It Fl o Ar ssh_option
+Specify an option to be directly passed to
+.Xr ssh 1 .
+.El
+.Sh INTERACTIVE COMMANDS
+Once in interactive mode
+.Nm ,
+understands a set of commands similar to those of
+.Xr ftp 1 .
+Commands are case insensitive.
+.Bl -tag -width Ds
+.It Ic CD Ar path
+Change remote directory to
+.Ar path
+.It Ic LCD Ar path
+Change local directory to

+.It Ic CHOWN Ar own Ar path
+Change owner of file
+.Ar path to
+.Ar own .
+.Ar own
+must be a numeric UID.
+.It Ic HELP
+Display help text
+.It Ic GET Ar remote-file Op Ar local-file
+Retrieve the
+.Ar remote-file
+and store it on the local machine.
+If the local
+file name is not specified, it is given the same name it has on the
+remote machine.
+.It Ic LLS Op Ar ls-options Op Ar path
+Display local directory listing of either
+.Ar path
+or current directory if
+.Ar path
+was not specified.
+.It Ic LMKDIR Ar path
+Create local directory specified by
+.Ar path
+.It Ic LPWD
+Print local working directory
+.It Ic LS Op Ar path
+Display remote directory listing of either

+or current directory, is
+.Ar path not specified.
+.It Ic LUMASK Ar umask
+Set local umask to
+.Ar umask
+.It Ic MKDIR Ar path
+Create remote directory specified by
+.Ar path
+.It Ic PUT local-file Op Ar remote-file
+Upload
+.Ar local-file
+and store it on the remote machine. If the local file name is not specified,
+it is given the same name it has on the local machine.
