.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 host
.Nm sftp
.Op [\fIuser\fR@]\fIhost\fR[:\fIfile\fR [\fIfile\fR]]
.Nm sftp
.Op [\fIuser\fR@]\fIhost\fR[:\fIdir\fR[\fI/\fR]] 
.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 second usage format will fetch files automaticly if a non-interactive 
authentication is used, else it do so after an interactive authentication 
is used.
.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
.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 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
Once in interactive mode,
.Nm
understands a set of commands similar to those of 
.Xr ftp 1 .
Commands are case insensitive and pathnames may be enclosed in quotes if they
contain spaces.
.Bl -tag -width Ds
.It Ic cd Ar path
Change remote directory to 
.Ar path .
.It Ic lcd Ar path
Change local directory to 
.Ar path .
.It Ic chgrp Ar grp Ar path
Change group of file 
.Ar path
to
.Ar grp .
.Ar grp
must be a numeric GID.
.It Ic chmod Ar mode Ar path
Change permissions of file 
.Ar path
to
.Ar mode .
.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 exit
Quit sftp.
.It Xo Ic get
.Op Ar flags
.Ar remote-path
.Op Ar local-path
.Xc
Retrieve the
.Ar remote-path
and store it on the local machine.
If the local
path name is not specified, it is given the same name it has on the 
remote machine. If the 
.Fl P
flag is specified, then the file's full permission and access time are
copied too.
.It Ic help
Display help text.
.It Ic lls Op Ar ls-options Op Ar path
Display local directory listing of either 
.Ar path
or current directory if
.Ar path
is not specified.
.It Ic lmkdir Ar path
Create local directory specified by
.Ar path .
.It Ic ln Ar oldpath Ar newpath
Create a symbolic link from 
.Ar oldpath
to
.Ar newpath .
.It Ic lpwd

.It Ic ls Op Ar path
Display remote directory listing of either
.Ar path
or current directory if
.Ar path
is not specified.
.It Ic lumask Ar umask

.Ar umask .
.It Ic mkdir Ar path
Create remote directory specified by
.Ar path .
.It Xo Ic put
.Op Ar flags
.Ar local-path
.Op Ar local-path
.Xc
Upload
.Ar local-path
and store it on the remote machine. If the remote path name is not 
specified, it is given the same name it has on the local machine. If the

flag is specified, then the file's full permission and access time are
copied too.
.It Ic pwd
Display remote working directory.
.It Ic quit
Quit sftp.
