1 key point - find

# expr1 -o expr2
#   Or; expr2 is not evaluated if expr1 is true.

# expr1 expr2
#   Two expressions in a row are taken to be joined with an  implied
#   "and"; expr2 is not evaluated if expr1 is false.

# expr1 -a expr2
#   Same with expr1 expr2

# -print
#    True; print the full file name on the standard output, followed
#    by a newline. If  you  are  piping  the output of find into
#    another program and there is the faintest possibility  that  the
#    files  which you are searching for might contain a newline, then
#    you should seriously consider using the -print0  option  instead
#    of  -print. 

# -path pattern
#    To  ignore  a whole directory tree, use -prune rather
#    than checking every file in the tree.  For example, to skip  the
#    directory  `src/emacs'  and  all files and directories under it,
#    and print the names of the other files found, do something  like
#    this:
#           find . -path ./src/emacs -prune -o -print
#    It  would  only  make sense to use an absolute path name here if
#    the relevant start point is also an absolute path.
