How do I increment a value in a textfile using the regular Windows command-line?

Question

I'd like to keep a "compile-counter" for one of my projects. I figured a quick and dirty way to do this would be to keep a text file with a plain number in it, and then simply call upon a small script to increment this each time I compile.

How would I go about doing this using the regular Windows command line?

I don't really feel like installing some extra shell to do this but if you have any other super simple suggestions that would accomplish just this, they're naturally appreciated as well.

Answer 1

You can try a plain old batchfile.

@echo off
for /f " delims==" %%i in (counter.txt) do set /A temp_counter= %%i+1
echo %temp_counter% > counter.txt

assuming the count.bat and counter.txt are located in the same directory.

Answer 2

It would be an new shell (but I think it is worth it), but from PowerShell it would be

[int](get-content counter.txt) + 1 | out-file counter.txt
