"No such file or directory" error while executing shell script

Question

I am executing the below
#!/bin/bash

###############################################################################
# This script can copy any file from Present machine to machine with IP as Test_ip and execute it :)  #
###############################################################################

############################ Main code starts here ####################################
Test_ip="10.20.12.206"

home=`pwd`
expect -c "
   spawn ssh root@$Test_ip \"mkdir /test_machine\"
   expect yes/no { send yes\r; exp_continue }
   expect password { send gaur\r; exp_continue }
   exit
        "
 expect -c "
   spawn scp $home/run_check_node.sh $home/script_3.sh $home/script_2.sh  root@$Test_ip:/test_machine/
   expect yes/no { send yes\r; exp_continue }
   expect password { send gaur\r; exp_continue }
   exit
        "       

expect -c "
    spawn ssh root@$Test_ip \"chmod +x /test_machine/run_check_node.sh /test_machine/script_2.sh /test_machine/script_3.sh;\"
    expect yes/no { send yes\r; exp_continue }
    expect password { send gaur\r; exp_continue }
    exit
        "

expect -c "
    spawn ssh root@$Test_ip \". /test_machine/script_2.sh\"
    expect yes/no { send yes\r; exp_continue }
    expect password { send gaur\r; exp_continue }
    exit
        "

The script shown is script_1.sh.

In the above code, I am creating a directory on Test_ip and then copying all 3 files ( script_2.sh, script_3.sh and run_check_node.sh) from current machine to other machine (Test_ip) using scp. Then I gave execute permission to them. When I am trying to do spawn ssh root@$Test_ip \". /test_machine/script_2.sh\", it is accepting password and then displaying "/test_machine/script_2.sh: No such file or directory".

I am not getting why it is telling like that. It just made all of them executable and at next command, claiming that the file does not exist!

it looks as though you copy the file to $home/script_2.sh but try and execute it from /test_machine/script_2.sh? — Jason Lewis, Jun 10 '14 at 07:16
for scp, i am copying files from `pwd` to `test_machine` directory on other machine. So, nothing seems like what you are thinking. — Aakash Goyal, Jun 10 '14 at 07:25
The working of scp command is: scp files_to_copy where_to_copy — Aakash Goyal, Jun 10 '14 at 07:28
There is more relevant information in this page [http://stackoverflow.com/questions/13298487/bash-script-to-ssh-into-a-machine-without-prompting-password-and-without-using-k] That may be worth a look as well. — David C. Rankin, Jun 10 '14 at 07:43
Well when you log in to those machines have those files actually been created? Perhaps the copy failed ... I don't know expect but it doesn't look to me like you check the error code returned. So if the previous command failed you just keep going. — dave, Jun 10 '14 at 07:48
@dave The files are there. That why I told that "I am not getting why it is telling like that. It just made all of them executable and at next command, claiming that the file does not exist!" — Aakash Goyal, Jun 10 '14 at 07:54

Instead of using
expect -c " spawn ssh root@$Test_ip \". /test_machine/script_2.sh\" expect yes/no { send yes\r; exp_continue } expect password { send gaur\r; exp_continue } exit "

use
expect -c " spawn ssh root@$Test_ip \"***bash*** /test_machine/script_2.sh\" expect yes/no { send yes\r; exp_continue } expect password { send gaur\r; exp_continue } exit "

Note: The . is replaced with bash above.

What I feel happening is, although the script script_2.sh is made executable, when trying to execute it from local machine to remote machine, because of using #!/bin/bash, it may not be allowing it to run as a shell script (by using . /file_path). See the difference between using bash and sh clearly here
