How can you do a one liner with sftp to login with the password on the same line?

Solution 1:

As others have mentioned, a command-line password should be the last resort.

However, if nothing else is possible; one can go for ssh pass

sshpass -p <password> sftp user@host

Solution 2:

Generally including a password in a command line is considered a security risk because it will show up to anyone else who can run ps/top, and it may be saved in your shell's history.

It would be a much better idea to setup key-based authentication if you are able.

Also, I don't believe it is going to be possible with sftp. It is meant to be used for secure transfers. If you really had to do something like this and you have no other choice then you probably need to be looking at automating with expect.

Solution 3:

Don't do that - setup SSH public key authentication for automatic login.

Solution 4:

Just use perl, ruby or python to script what you are trying to do. In case of ruby it's just (taken from the net-sftp API docs):

require 'net/sftp'

Net::SFTP.start('host', 'username', :password => 'password') do |sftp|

  # upload a file or directory to the remote host

  sftp.upload!("/path/to/local", "/path/to/remote")

end

Solution 5:

As the other answers have stated, use public key authentication. There is a great, although a little dated, IBM developerWorks series that should explain everything you want to know about it, as well as some useful supplemental tools such as keychain.
