psftp [options] [user@]host
psftp is an interactive text-based client for the SSH-based SFTP (secure file transfer) protocol.
The command-line options supported by psftp are:
Show version information and exit.
Display the fingerprints of the PuTTY PGP Master Keys and exit, to aid in verifying new files released by the PuTTY team.
- -b batchfile
Use specified batchfile.
Output batchfile commands.
Don't stop batchfile processing on errors.
Show verbose messages.
- -load session
Load settings from saved session.
- -P port
Connect to port port.
- -proxycmd command
Instead of making a TCP connection, use command as a proxy; network traffic will be redirected to the standard input and output of command. command must be a single word, so is likely to need quoting by the shell.
The special strings %host and %port in command will be replaced by the hostname and port number you want to connect to; to get a literal % sign, enter %%.
Backslash escapes are also supported, such as sequences like \n being replaced by a literal newline; to get a literal backslash, enter \\. (Further escaping may be required by the shell.)
(See the main PuTTY manual for full details of the supported %- and backslash-delimited tokens, although most of them are probably not very useful in this context.)
- -l user
Set remote username to user.
Disable interactive prompts.
By default, PSFTP will filter control characters from the standard error channel from the server, to prevent remote processes sending confusing escape sequences. This option forces the standard error channel to not be filtered.
- -pw password
Set remote password to password. CAUTION: this will likely make the password visible to other users of the local machine (via commands such as `w').
Force use of SSH protocol version 1.
Force use of SSH protocol version 2.
Force use of the `bare ssh-connection' protocol. This is only likely to be useful when connecting to a psusan(1) server, most likely with an absolute path to a Unix-domain socket in place of host.
Force use of the SSH protocol. (This is usually not needed; it's only likely to be useful if you need to override some other configuration of the `bare ssh-connection' protocol.)
- -4, -6
Force use of IPv4 or IPv6 for network connections.
Enable SSH compression.
- -i keyfile
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.
If you are using an authentication agent, you can also specify a public key here (in RFC 4716 or OpenSSH format), to identify which of the agent's keys to use.
Don't try to use an authentication agent.
Allow use of an authentication agent. (This option is only necessary to override a setting in a saved session.)
- -hostkey key
Specify an acceptable host public key. This option may be specified multiple times; each key can be either a fingerprint (SHA256:AbCdE..., 99:aa:bb:..., etc) or a base64-encoded blob in OpenSSH's one-line format.
Specifying this option overrides automated host key management; only 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.
- -sshlog logfile
- -sshrawlog logfile
These options make psftp log protocol details to a file. (Some of these may be sensitive, although by default an effort is made to suppress obvious passwords.)
-sshlog logs decoded SSH packets and other events (those that -v would print). -sshrawlog additionally logs the raw encrypted packet data.
If PSFTP is configured to write to a log file that already exists, discard the existing file.
If PSFTP is configured to write to a log file that already exists, append new log data to the existing file.
