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.
