Here document supports user interaction?
Hi,
I am trying to ssh into a remote machine and then enter a vserver on the remote machine. I am using here document to carry out these commands on the remote machine. My here document looks like this
Code:
ssh username@remotemachine  << HERE
sudo vserver vservername enter
HERE

however the sudo vserver vservername enter does not wait for user interaction which is to enter a passphrase for sudo. It simply prompts me for password 3 times and exists. Smilie

How do i handle user interaction inside a here document,!

DESCRIPTION

       hwloc-assembler-remote is a frontend to hwloc-assembler.  It takes care of retrieving the remote nodes' topologies before  assembling  them
       with hwloc-assembler.

EXAMPLES

       To assemble three nodes topologies:

	   $ hwloc-assembler-remote output.xml host1 host2 host3

       To assemble the topology of a multi-process MPI job defined as a machinefile:

RETURN VALUE

       Upon successful execution, hwloc-assembler-remote returns 0.
