Hi Chris,


-f Requests ssh to go to background just before command
execution. This is useful if ssh is going to ask
for passwords or passphrases, but the user wants it
in the background.

I presume that "-f" is the same thing as a local "bg" or "&"
background command. Especially if it is going to ask me for
a password. How does one enter a password, if it is in the background?
Why would I want to run this in the background
anyway?

What am I missing?

No, it's not the same at all. (Re-read the second sentence that you've
quoted, above.)

It isn't in the background when it asks for a password. Once it has
established the connection - including any password/token negotiation -
and is about to fire off the command, it backgrounds itself.

Because that appears to be what you're trying to achieve.
