pass a password to sudo su
===

I wanted to sudo to different user after ssh'ing into remote server, for this i tried the following:

    cat remote-test.sh
    ssh -t -t abcuser@test-server.net 'bash -s' << EOF
      /tmp/test.sh
    EOF

when i execute the remote-test.sh from development-server.net, I wanted to ssh to test-server.net as abcuser and then sudo as xyzuser .

    cat /tmp/test.sh
    
    echo "password" | sudo -S su - xyzuser
    cd /tmp/some/directory

Can someone please advice how to pass a password while doing sudo su in a script.
