search for files in a directory hierarchy

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

-type c
       File is of type c:

       b      block (buffered) special

       c      character (unbuffered) special

       d      directory

       p      named pipe (FIFO)

       f      regular file

       l      symbolic link; this is never true if the -L option or the  -follow  option  is  in  effect,
              unless the symbolic link is broken.  If you want to search for symbolic links when -L is in
              effect, use -xtype.

       s      socket

       D      door (Solaris)

-maxdepth levels
       Descend  at  most  levels  (a  non-negative  integer) levels of directories below the command line
       arguments.  -maxdepth 0
        means only apply the tests and actions to the command line arguments.

-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.
