Batch file: program output in different folder

Question

So I'm using luac to compile some .lua into .lub recursively through a batch file.

I'm also having an issue that the output of the luac (same name as the .lua, but with .lub extension) is not going to the folder where the .lua was found.

I've used:

for /r %%r in (*.lua) do luac5.1.4.exe -o "%%~nr.lub" "%%r"

and the .lub of a .lua in a deeper folder is outputted in the root folder.

What should I change in the script so it outputs inside the .lua's location folder?

Answer 1

I solved this situation simply altering the end of the script. It now looks like this:

for /r %%r in (*.lua) do "luac5.1.4.exe" -o "%%~pnr.lub" "%%r"

Now the batch will output to %%~pnr, which serves as the file name and its path, excluding the extension, so I could add the .lua at the end, solving this little issue.
