qsh find syntax help

Hi Folks, Merry Christmas and Happy Holidays and happy new year to you
all.

I have a question about qsh command syntax to find where ever the
string/word tivoli is found on any file in my ifs.
I can run this cmd;
find /home/frbocchino -name ''*.log'' -exec grep -rl ''tivoli'' {} \; which
will return a list of .log files that contain tivoli in them for directory
/home/frbocchino but now I want to run the find command that will search
the entire root and all subdirectories and all file types and return the
list of files containing tivoli...what's the proper syntax for that? I
know / will replace /home/frbocchino but what should replace .log? Any
info or help appreciated, Frank
