read on remote machine

I want to run read using a local bash script on a remote machine. It works in a string but not as a file.


anon@HP-xw4600:~$ ssh anon@aids.net "read aids ; echo \$aids"
anon@aids.net's password:
aids!
aids!
anon@HP-xw4600:~$ ssh anon@aids.net 'bash -s' < aids.sh
anon@aids.net's password:
anon@HP-xw4600:~$ cat aids.sh
#! /bin/bash
read aids
echo \$aids
exit 0

Tell me why-eee!

And what happens when you remove 'bash -s'? Ie, you just type

ssh anon@aids.net < aids.sh
