How to make a toggle switch in batch?
I need a batch file that will toggle between running two command lines;
nircmd.exe setdefaultsounddevice "Speakers"
The other being
nircmd.exe setdefaultsounddevice "Headset"
Ive tried using the existence of a .txt file as a flag, but for some reason it just always sees it as not existing. How do you make a batch file (silently) tick/tock every time it runs?
You can store the toggle value in the Batch file itself in a very simple way:
@echo off setlocal rem Get current value and update it call :GetToggle set /P "=+1" < nul >> "%~F0" set /A "toggle%%=2" if %toggle% equ 0 ( echo Set "Speakers" ) else ( echo Set "Headset" ) goto :EOF :GetToggle rem Be sure that next line does NOT end in CR+LF: set /A toggle=0
This method works correctly for a little less than 4096 times. If the Batch file run once everyday, this covers more than 11 years! If this is not enough for you, just add an
if command after get the toggle value to check if it exceeds 4090, and in such a case insert a breaking CR+LF characters at end of the file followed by a new line with
set /A toggle=0
Note that this method also allows to know how many times the Batch file had been used, so it may be used in other scenario...

A good solution is to store the switch in an
ADS (alternative data stream) in the bat itself (will work only if your file system is
You just will get a
file not found warning at the first run while it can find the
ADS stream but after that it will be created
@echo off set "$activ=" set /p $activ=<%~nx0:activ if not defined $activ ( echo speaker>%~nx0:activ set "$activ=speaker" ) echo actual [%$activ%] if /i "%$activ%"=="speaker" ( nircmd.exe setdefaultsounddevice "Headset" echo headset>%~nx0:activ ) else ( nircmd.exe setdefaultsounddevice "Speakers" echo speaker>%~nx0:activ )
EDIT : Thanks
@aschipfl here is the solution to avoid the first run Warning
@echo off set "$activ=" 2> nul (set /P $activ= < "%~nx0:activ") || set "$activ=speaker" echo actual [%$activ%] if /i "%$activ%"=="speaker" ( nircmd.exe setdefaultsounddevice "Headset" echo headset>%~nx0:activ ) else ( nircmd.exe setdefaultsounddevice "Speakers" echo speaker>%~nx0:activ )
very easy and don't need any temp file and don't have call limitation

- Edit your question to include the code you tried, which uses the existence of a
.txtfile as a flag, but always sees it as not existing. We cannot help you with your failing code if we cannot see it, and not posting it means you're expecting somebody to write the script for you, (which is rude and off-topic).

- It would be very useful if you simply edited your answer to include the information so people like me who don't know very much about coding can simply change the name of the device. I still don't know where to put those lines. Thanks!
- does nircmd.exe setdefaultsounddevice "Speakers" go after echo set or before? please help
- Ok ignore me then. I'll find help somewhere else.
- I just was about to suggest to use
if existfor the very first run, but then I found that this does not work for ADSs, unfortunately. What you could do though is:
2> nul (set /P $activ= < "%~nx0:activ") || set "$activ=speaker". Anyway, nice approach!
- Thanks @aschipfl ! Better and Cleaner ! Edited with your solution too!
- this works great but only works once. Any ideas why?
