 .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 host ,
 then enters an interactive command mode.
 .Pp
 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.
 .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

 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 a symbolic link from
 .Ar oldpath
 to
 .Ar newpath .
 .It Ic lpwd

 or current directory if
 .Ar path
 is not specified.

 Set local umask to
 .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
 .Fl P
 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.
 .It Ic rename Ar oldpath Ar newpath
 Rename remote file from
 .Ar oldpath
 to
 .Ar newpath .
 .It Ic rmdir Ar path
 Remove remote directory specified by
 .Ar path .
