ipconfig: merge two batch files (.bat) into one

Question

I have two .bat files in use to toggle my Internet connection:

1) "ipconfig /release" (to switch off)

2) "ipconfig /renew" (to switch on)

Could somebody please rewrite it, so I can use ONE single file instead of two?

Specifically:

• one click - switch off;
• another one (no delay, any time, same file) - switch on;
• and so on, and so on (just clicking, without any other actions required).

Answer 1

This uses a toggle file in the batch file directory to implement the behaviour.

pushd
if exist __toggle__.txt (
    del __toggle__.txt
    ipconfig /renew
) else (
    echo. > __toggle__.txt
    ipconfig /release
)
