find bash.exe location from a .bat file if only git.exe is in %PATH%

[Ilia Basin]

Hi. In my git for windows installation only git.exe is in path. I'm writing a wrapper .bat file that is supposed to launch the actual .sh file and I need to find the proper shell interpreter (and not launch WSL by accident). Can git print the location of bash it uses for hooks and other scripts?

I do not know whether GfW provides "something" which you could "query"
to find the location of bash.exe, but possibly you could roll like this:

* The location of bash.exe may be expected to be reasonably stable
between GfW releases.

* It is supposedly also stable relative to the location of git.exe.

* Since git.exe is in the path, you could first locate its full pathname -
say, calling

where git.exe

if writing a batch (for cmd.exe), or something analogous in other
environments.

* Use other tools for path manipulation to construct the pathname
of bash.exe.
