remote sudo from local script with local redirection

Question

Okay I'm sure this has been asked before but the life of me I can't find an answer (it's not possible / how to do it).

I have a shell script script.sh which runs a command on a remote server using:

    ssh -t [SERVER] "[COMMAND TO BE EXECUTED REMOTELY]"

This works fine including if the command contains sudo.

However, sometimes I redirect the output of this script.sh and of course if the remote command contains sudo the sudo password prompt is redirected also.

Is there a way to:

    ./script.sh > script.out

and still get the remote sudo password prompt on the terminal?

Passing the sudo password on the cli for script.sh is not an option.

Many thanks,

Alasdair.

You can use tee to duplicate the standard input:

./script.sh | tee script.out

After that you can filter what is output with an awk command

./script.sh | tee script.out | awk '/^Password/ {print;}'
