-path pattern
File name matches shell pattern pattern. The metacharacters do not treat `/' or `.' specially; so, for example, 
find . -path './sr*sc' 
will print an entry for a directory called './src/misc' (if one exists). 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
