psftp — interactive SFTP (secure file transfer protocol) client


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.
-l user
Set remote username to user.
Disable interactive prompts.
-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.
Enable SSH compression.
-i path
Private key file for user authentication.
-hostkey key

Specify an acceptable host public key. This option may be specified multiple times; each key can be either a fingerprint (99:aa:bb:...) 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.
