how can recursively copy user-executable files in folder folder? example, have in folder folder/one : -rwxrwxr-x 1 user group 7777777 jun 1 12:00 executable1 -rw-rw-r-- 1 user group 4444 jun 1 12:00 text1.txt in folder folder/two : -rwxrwxr-x 1 user group 7777777 jun 1 12:00 executable2 -rw-rw-r-- 1 user group 4444 jun 1 12:00 text2.txt it should recursively copy executable1 , executable2 folder destination folder without preserving original hierarchy. destination folder should have: -rwxrwxr-x 1 user group 7777777 jun 1 12:00 executable2 -rwxrwxr-x 1 user group 7777777 jun 1 12:00 executable1 you use find command: find folder -type f -executable -exec echo "{}" /tmp \; replace echo cp -p after verify output correct.

i have backend in laravel, rest api, because i'm using angularjs in fronend , making ajax requests. let's have make crud users and don't know if there difference between putting of parameters in route or of them in form input. for example: route::post('/users/update', 'userscontroller@update); and call 'id' parameter from: input::get('id') or route::post('/users/update/:id', 'userscontroller@update); and include parameter of function update like: public function update($id) { } is there real difference between 2 ways? maybe security issues? coding standards? or same? should use laravel's rest controllers? if building rest api should have url example.com/posts/42 , not example.com/posts?id=42 because cleaner , coding standard. i drop uppercase characters in urls , go second choice of implementation. way, if need update user should use put request so: put users/:id .
