+git-whatchanged -p v2.6.12.. include/scsi drivers/scsi::
+
+       Show as patches the commits since version 'v2.6.12' that changed

+
+git-whatchanged --since="2 weeks ago" \-- gitk::
+
+       Show the changes during the last two weeks to the file 'gitk'.
+       The "--" is necessary to avoid confusion with the *branch* named
