Command used: sed -i -e '/file is part of /d' $(git grep "file is part of " |egrep ":( */\*.*\*/\$|#|;#|-- | *\* )" | cut -d: -f1 |grep -v crossgcc |grep -v gcov | grep -v /elf.h |grep -v nvramtool) The exceptions are for: - crossgcc (patch file) - gcov (imported from gcc) - elf.h (imported from GNU's libc) - nvramtool (more complicated header) The removed lines are: - fmt.Fprintln(f, "/* This file is part of the coreboot project. */") -# This file is part of a set of unofficial pre-commit hooks available -/* This file is part of coreboot */ -# This file is part of msrtool. -/* This file is part of msrtool. */ - * This file is part of ncurses, designed to be appended after curses.h.in -/* This file is part of pgtblgen. */ - * This file is part of the coreboot project. - /* This file is part of the coreboot project. */ -# This file is part of the coreboot project. -# This file is part of the coreboot project. -## This file is part of the coreboot project. --- This file is part of the coreboot project. -/* This file is part of the coreboot project */ -/* This file is part of the coreboot project. */ -;## This file is part of the coreboot project. -# This file is part of the coreboot project.
