Wrench How to write automated interactive shell script?

Hello everyone, I just want to write a shell script for automatic feeding the username and password prompts when running my commands,
I tried this one but it did not work. Please help me for any way out.

Code:
#!/bin/bash
#!/usr/bin/expect

cd ~/workspace/mimosanetworks_mimosa-nms

ls -ltr

spawn sudo git pull

expect "[sudo] password for sandeep:"

send "sandeep123\n"

expect "Username :"

send "sandeep\n"

expect "Password :"

send "sandeep121\n"

Code:
sandeep@K2-Sandeep-08:~$ ./checkout.sh 
total 64
./checkout.sh: line 8: spawn: command not found
couldn't read file "Username:": no such file or directory
./checkout.sh: line 16: send: command not found
couldn't read file "Password:": no such file or directory
./checkout.sh: line 20: send: command not found

i would strongly advise against scripting a password-required process for the usual security reasons ...

anyways, see if a here document could work for you ... (see sample below) ...
Code:
otto@susegeek:~> su - << EOF
> B0r3d2!
> id
> ps
> EOF
Password: uid=0(root) gid=0(root) groups=0(root)
  PID TTY          TIME CMD
 6423 pts/1    00:00:00 su
 6426 pts/1    00:00:00 bash
 6455 pts/1    00:00:00 ps
