It makes whole executable process quicker on UNIX, especially for large bundles containing many files, since using find narrows results to only files having executable flags then all further tests follow. Since find ... -perm +0111 is not clearly POSIX compliant and some Linux versions refuse it, it is better to use longer but portable: find ... -perm \( -perm -0100 -o -perm -0010 -o -perm -0001 \)
