Batch that would open CMD and execute commands without closing CMD

Question

I have a testt.bat file that contains:

echo abc
echo cba

When I open command prompt and enter testt.bat I receive output:

C:\>testt.bat
C:\>echo abc
abc
C:\>echo cba
cba
C:\>

The command prompt stays open waiting for me to enter more commands.

Problem: If I double click testt.bat I receive the same output but cmd exits immediately. I want to be able to keep the prompt and enter more commands.

So basically I want to integrate the "opening CMD" part into the batch file.

I've tried:

start cmd /k "echo abc" & "echo bca"

but it only executes the first part "echo abc" without the second part.

Edit: I managed to do it by creating a second batch file "TESTX.bat" that contains:

start testt.bat

Is there a way to do the same thing without needing to use 2 batch files?

Answer 1

This should work for you.

start cmd /k "echo abc & echo bca"

Answer 2

add pause at the end and you will recieve something like press any key to continue

or, if its only echo commands you could do something like:

@echo off
:set1
echo abc
echo cba
cls
goto set1

and if you want that C:/> to be gone, just type @echo off in the beginning.
