Shell csript linux auto connect ssh to server and deployment

I want deploy code to server. I dont want connect ssh in command. I write shell script linux auto connect to server and cd go to directory project and execute git command or svn command if it done exit connect .

- Step 1:  Install package expect  if not install on my computer.
- Step 2 : create file deploy_project.sh and paste code .

#!/usr/bin/expect

set login "root" # user  login

set addr "192.168.1.44" # ip server 

set pw "123456" # password login ssh 

spawn ssh $login@$addr

expect "$login@$addr\'s password:"

send "$pw\r"

expect "#"

send "cd /var/www/html/project_example\r" # go to directory project

expect "#"

send "git pull\r" # command git pull source code

expect "#"

send "exit\r" # disconnect to server 

interact # close shell

- Step 3 Open terminal cd to directory  run command ./deploy_project.sh

Please have any questions. 

Good Luck !
