It's also suitable for use with git-send-email --cc-cmd Some examples picking a random file (drivers/net/b44.c): Get maintainers for a single file (this includes git -by: signatories and the script does a sort | uniq so the maintainer is not listed first) $ ./scripts/get_maintainer.pl -f drivers/net/b44.c "Miguel Botón" <mboton@...il.com> Gary Zambrano <zambrano@...adcom.com> Jeff Garzik <jeff@...zik.org> Jeff Garzik <jgarzik@...ox.com> John W.
