grep random "#include <(bits/)?random(\.h)?>" *

expected: on the include/c++/bits dir of a gcc compiler should produce a couple of results.

actual: produces pages and pages with just about every file in it. anything with the word random in it. grep is ignoring #include <(bits/)? and (\.h)?> and I have no clue why.

all I wanted was the header files in the compiler which #included anything related to random.h because I had a bug in gcc I was trying to report, so I ended up finding a bug in grep too.
