Interactive Putty after remote commands & remotely sudo login

Question

I'm trying to run commands in putty remotely & unfortunately i stuck on two problems.

Putty cli closed after running those commands.

I want sudo login remotely without prompt for password

Note: I already found solution for both problems & posting this question for future use.

Answer 1

First problem solution detail in here

Second problem solved by first two line of RemoteCommands.txt first line suggested here & after running that i run sudo -i to do sudo login but it didn't prompt for password. so it solve accidentally.

VBScript.vbs

Set WshShell = WScript.CreateObject("WScript.Shell")

WshShell.Exec("C:\Putty\putty.exe -ssh <username>@<ip> -pw <password> -P <port> -m ""E:\putty\RemoteCommands.txt"" -t")

RemoteCommands.txt

sudo -S <<< "<password>" ls
sudo -i
/bin/bash

BatchFile.bat to run vbscript easily

@echo off
start cmd /k "cd /d E:\putty & cscript VBScript.vbs & exit"

Edited

To run commands after sudo login you can write something like this

sudo -i -- bash -c 'cmd1; cmd2' or sudo -i -- bash -c 'cmd1 && cmd2'

I found this workaround from this link & with random tries. so i got no explanation about this :D ... if any one know detail about this please edit this answere & provide links

RemoteCommands.txt

sudo -S <<< "<password>" ls
sudo -i -- bash -c 'cd /home/shajji && npm start && /bin/bash'
/bin/bash
