Pseudo-terminal will not be allocated because stdin is not a terminal auto login

[admin]

I write the following command :

#!/bin/bash
echo "Connecting to Server.......";
# ssh pass is third party first install it by sudo apt-get install sshpass
sshpass -p "xxxxxxxx" ssh -o StrictHostKeyChecking=no username@domain.com -p 22 <<EOF
  cd /home/same/public_html/
  ls
EOF

Output :

Everything working well but a line shows and the text come

Solution :

Try ssh -t -t(or ssh -tt for short) to force pseudo-tty allocation even if stdin isn’t a terminal.

See also: Terminating SSH session executed by bash script

From ssh man page:

-T      Disable pseudo-tty allocation.

-t      Force pseudo-tty allocation.  This can be used to execute arbitrary 
        screen-based programs on a remote machine, which can be very useful,
        e.g. when implementing menu services.  Multiple -t options force tty
        allocation, even if ssh has no local tty.
