search for files in a directory hierarchy

find [-H] [-L] [-P] [-D debugopts] [-Olevel] [path...] [expression]

-iname pattern
       Like  -name,  but  the match is case insensitive.  For example, the patterns `fo*' and `F??' match
       the file names `Foo', `FOO', `foo', `fOo', etc.   In these patterns, unlike filename expansion  by
       the  shell,  an  initial  '.' can be matched by `*'.  That is, find -name *bar will match the file
       `.foobar'.   Please note that you should quote patterns as a matter of course, otherwise the shell
       will expand any wildcard characters in them.
