Done with this script: cd hw for i in `find . -name '*.h' | sed 's/^..//'`; do echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,' done | sed -i -f - `find . -type f` This is so that paths remain valid as files are moved. Instead, files in hw/dataplane are referenced with the relative path. We know they are not going to move to include/, and they are the only include files that are in subdirectories _and_ move.
