can someone please suggest, I am trying to update user password on remote server. user who is trying to run this script have sudo rules setup with password less. I am not sure where I am missing here.

Code:
$ ssh -t 10.10.10.89 "bash -s" < 'sudo echo Welcome | passwd --stdin neen'
-bash: sudo echo Welcome | passwd --stdin neen: No such file or directory
$ ssh -t 10.10.10.89 "bash -s" < sudo echo Welcome | passwd --stdin neen
-bash: sudo: No such file or directory
Only root can do that.
$

Thanks,

< doesn't work that way. Try a here-document.

Code:
ssh -t 10.10.10.89 <<EOF
        echo "password" | sudo passwd --stdin username
EOF

It's entirely possible sudo isn't configured to allow you to do that, and/or passwd can't take passwords from stdin.
