.SH "DESCRIPTION"
.PP
\fBpsftp\fP is an interactive text-based client for the SSH-based SFTP (secure file transfer) protocol.
.SH "OPTIONS"
.PP
The command-line options supported by \fBpsftp\fP are:
.IP "\fB-V\fP"
Show version information and exit.
.IP "\fB-pgpfp\fP"
Display the fingerprints of the PuTTY PGP Master Keys and exit, to aid in verifying new files released by the PuTTY team.
.IP "\fB-b\fP \fIbatchfile\fP"
Use specified batchfile.
.IP "\fB-bc\fP"
Output batchfile commands.
.IP "\fB-be\fP"
Don't stop batchfile processing on errors.
.IP "\fB-v\fP"
Show verbose messages.
.IP "\fB-load\fP \fIsession\fP"
Load settings from saved session.
.IP "\fB-P\fP \fIport\fP"
Connect to port \fIport\fP.
.IP "\fB\-proxycmd\fP \fIcommand\fP"
Instead of making a TCP connection, use \fIcommand\fP as a proxy; network traffic will be redirected to the standard input and output of \fIcommand\fP. \fIcommand\fP must be a single word, so is likely to need quoting by the shell.
.RS
.PP
The special strings \fB%host\fP and \fB%port\fP in \fIcommand\fP will be replaced by the hostname and port number you want to connect to; to get a literal \fB%\fP sign, enter \fB%%\fP.
.PP
Backslash escapes are also supported, such as sequences like \fB\en\fP being replaced by a literal newline; to get a literal backslash, enter \fB\e\e\fP. (Further escaping may be required by the shell.)
.PP
(See the main PuTTY manual for full details of the supported \fB%\fP- and backslash-delimited tokens, although most of them are probably not very useful in this context.) 
.RE
.IP "\fB-l\fP \fIuser\fP"
Set remote username to \fIuser\fP.
.IP "\fB-batch\fP"
Disable interactive prompts.
.IP "\fB-pw\fP \fIpassword\fP"
Set remote password to \fIpassword\fP. \fICAUTION:\fP this will likely make the password visible to other users of the local machine (via commands such as `\fBw\fP').
.IP "\fB-1\fP"
Force use of SSH protocol version 1.
.IP "\fB-2\fP"
Force use of SSH protocol version 2.
.IP "\fB-4\fP, \fB-6\fP"
Force use of IPv4 or IPv6 for network connections.
.IP "\fB-C\fP"
Enable SSH compression.
.IP "\fB-i\fP \fIkeyfile\fP"
Private key file for user authentication. For SSH-2 keys, this key file must be in PuTTY's PPK format, not OpenSSH's format or anyone else's.
.RS
.PP
If you are using an authentication agent, you can also specify a \fIpublic\fP key here (in RFC 4716 or OpenSSH format), to identify which of the agent's keys to use. 
.RE
.IP "\fB\-noagent\fP"
Don't try to use an authentication agent.
.IP "\fB\-agent\fP"
Allow use of an authentication agent. (This option is only necessary to override a setting in a saved session.)
.IP "\fB\-hostkey\fP \fIkey\fP"
Specify an acceptable host public key. This option may be specified multiple times; each key can be either a fingerprint (\fB99:aa:bb:...\fP) or a base64-encoded blob in OpenSSH\*(Aqs one-line format.
.RS
.PP
Specifying this option overrides automated host key management; \fIonly\fP the key(s) specified on the command-line will be accepted (unless a saved session also overrides host keys, in which case those will be added to), and the host key cache will not be written. 
.RE
.IP "\fB\-sshlog\fP \fIlogfile\fP"

.IP "\fB\-sshrawlog\fP \fIlogfile\fP"
These options make \fBpsftp\fP log protocol details to a file. (Some of these may be sensitive, although by default an effort is made to suppress obvious passwords.)
.RS
.PP
\fB\-sshlog\fP logs decoded SSH packets and other events (those that \fB\-v\fP would print). \fB\-sshrawlog\fP additionally logs the raw encrypted packet data.

.SH "MORE INFORMATION"
