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:
- -V
- Show version information and exit.
- -pgpfp
- 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.
- -bc
- Output batchfile commands.
- -be
- Don't stop batchfile processing on errors.
- -v
- 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.
- -batch
- Disable interactive prompts.
- -no-sanitise-stderr
- 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.
- -pwfile
filename
- Open the specified file, and use the first line of text read from it as
the remote password.
- -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 `ps' or `w'). Use -pwfile
instead.
- -1
- Force use of SSH protocol version 1.
- -2
- Force use of SSH protocol version 2.
- -ssh-connection
- 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.
- -ssh
- 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.
- -C
- 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.
- -noagent
- Don't try to use an authentication agent.
- -agent
- Allow use of an authentication agent. (This option is only necessary to
override a setting in a saved session.)
- -no-trivial-auth
- Disconnect from any SSH server which accepts authentication without ever
having asked for any kind of password or signature or token. (You might
want to enable this for a server you always expect to challenge you, for
instance to ensure you don't accidentally type your key file's passphrase
into a compromised server spoofing PSFTP's passphrase prompt.)
- -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.
- -logoverwrite
- If PSFTP is configured to write to a log file that already exists, discard
the existing file.
- -logappend
- If PSFTP is configured to write to a log file that already exists, append
new log data to the existing file.
