Yes and no. It's a POSIX glob, which means "**" is equivalent to "*", 
and that's what's supported. Whether it's MS-Windows shouldn't matter.

Looks like you found it already.

Hello,

I was using grep for Windows version 3.5.

I was trying to pattern match files.

At first, I thought I could put a regex as the file pattern in the command, but that didn't seem to work.

Then I looked at the --include option.

I tried

grep -l --include="**/*.xml" foo .
grep -l --include="**\*.xml" foo .
grep -l --include="**\\*.xml" foo .

Adding the recursive -r didn't help either.

However, this worked:
grep -rl --include="*.xml" foo .

Is the double star supported on Windows? What is the proper way to do it?

All the best,

Alex
