No need to use expect.

First, you need set a ssh keyless pass with root on all servers. With that, you needn't provide password to ssh to other servers.

Second, set your new password on your local server. and get the new unix keypass from /etc/shadow.

Code:
nimo:QKDPc5E$S.:12825:0:90:5:30:13096:

run the command: (sample only)

Code:
for server in `cat server_list`
do
   ssh root@$server perl -pe -i.bak 's/^nimo:$SWlkjRWexrXYgc98F/^nimo:QKDPc5E$S./' /etc/shadow
done

Please test it on one server first, then go for next servers.

if the Unix keypass includes \ or some other special chars, maybe you need add \ before them.
