@Rudic I tried using the -b option of sftp but it is still failing.

I changed by ssh_commands.txt as below:

Code:
cd /app/sftp;    <--- success
touch insidesftp.txt;   <--- success
echo "cd Moht;" >execmd.txt  <--- success
echo "get *;" >>execmd.txt  <--- success
echo "quit;" >>execmd.txt   <--- success
sshpass -p mypass -b execmd.txt sftp myuser@10.9.88.195;   <--- Fails (Although the command executes on remote Linux host I get an error in output)
touch sftpcompleted.txt    <--- success

Below is the error received:
Code:
EFT Server Enterprise 7.3.2.8Permission denied (password,keyboard-interactive).
Couldn't read packet: Connection reset by peer

However, when i fire the command manualy one by one this works fine. See output of Manual steps.

Code:
sshpass -p mypass sftp myuser@10.9.88.195
EFT Server Enterprise 7.3.2.8Connected to 10.9.88.195.
sftp> cd Moht
sftp> get *
Fetching /Moht/Jenkins_v1.0.docx to Jenkins_v1.0.docx
sftp> quit
[me_user@myremotelinuxhost sftp]$

Also the terminal closes instead of getting me the shell prompt.

Same point? Same error?

Sounds like a "permission denied" error (to me). Are you sure about the users including their respective permissions and the applications / programs / commands (putty, ssh, sftp) on ALL THREE sides (windowsuser@windowssystem, myuser@10.8.66.126, myuser@10.9.88.195) of your experiment? Where do the scripts reside?

How about trying
Code:
sshpass -p mypass -b execmd.txt sftp myuser@10.9.88.195

in manual steps?

That's why you need to run / exec your shell after having closed the sftp connection.

@Rudic

Code:
$ cat getcmd.txt 
cd Moht
get *
quit

We have come to a point that this has nothing to do with windows as all issues have been addressed with your help / inputs.

The current issue i wish to deal with is when i fire the below command manually on target Linux host i get the below error:
Code:
sshpass  -p mypass sftp -b getcmd.txt myuser@10.9.88.195
EFT Server Enterprise 7.3.2.8Permission denied (password,keyboard-interactive).
Couldn't read packet: Connection reset by peer

However; removing the -b parameter resolves the issue in a way that I'm able to login to sftp and then i can fire the commands in getcmd.txt one by one manually successfully on sftp prompt like below.

Code:
$ sshpass  -p mypass sftp myuser@10.9.88.195
EFT Server Enterprise 7.3.2.8Connected to 10.9.88.195.
sftp> cd Moht
sftp> get *
Fetching /Moht/Jenkins_v1.0.docx to Jenkins_v1.0.docx
sftp> quit
[ sftp]$

For some reason it is not liking the -b option. I have made sure that getcmd.txt file has 775 file permission.

Can you please suggest ?

sftp's -b option doesn't seem to cooperate well with sshpass, which in itself is a security risk. Comments on the net: Never Use on Production Server, Users of sshpass are encouraged to use one of the other password passing techniques, which are all more secure.

man sshpass:

- doesn't sound too secure, does it?

Quote:
-b batchfile
Batch mode reads a series of commands from an input batchfile instead of stdin. Since it lacks user interaction it should be used in conjunction with non-interactive authentication
So - all that boils down to: Consider non-interactive, passwordless authentication.
