You're right.  I knew there was something wrong with using the -H switch
in this circumstance, but I never went back and investigated why after
David's post.  Also, if you don't care about grep's output, you can
redirect it to /dev/null, and just get the name of the jar file.

Then again, if that's what you want, you could just do "grep -H *.jar".
