.Sh NAME
.Nm sftp
.Nd Secure file transfer program
.Sh SYNOPSIS
.Nm sftp
.Op Fl vC
.Op Fl b Ar batchfile
.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 b Ar batchfile
Batch mode reads a series of commands from an input
.Ar batchfile
instead of
.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
.Ic lmkdir .
.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 .
.It Fl v
Raise logging level. This option is also passed to ssh.
.El
.Sh INTERACTIVE COMMANDS

.Nm
understands a set of commands similar to those of 
.Xr ftp 1 .
Commands are case insensitive.
