UNIX for Dummies Questions & Answers

Have a sudo statement inside of a here document. It prompts me for a password, but doesnt wait for me to enter my password. Is there a way I can use the command without sudo or anyway that I can enter the password correctly?

Eg :

Code:

while read  remotehost
do
  ssh -t $2@$remotehost  <<REMOTE

   ls /path/to/file/ | while read line
     do
              sudo  vserver \$line enter
              echo "\$line Hello world"
      done

REMOTE
done < "$remotehostlist"

This asks for password for the following line sudo vserver $line enter. But it doesnt wait for me to enter password. Also if I type something it appears in cleartext.

Please help!!
