test@localhost: /unix find . -maxdepth 1 -size 0 -ls
90353467524120775 0 drwxr-xr-x 1 test Domain Users 0 Jun 15 11:43 .
9007199255261921 0 -rw-r--r-- 1 test Domain Users 0 Jun 15 11:44 ./empty.txt
19421773393554899 0 drwxr-xr-x 1 test Domain Users 0 Jun 15 11:43 ./empty_dir
test@localhost: /unix find . -maxdepth 1 -size 0 -ls
90353467524120775 0 drwxr-xr-x 1 test Domain Users 0 Jun 15 11:43 .
9007199255261921 0 -rw-r--r-- 1 test Domain Users 0 Jun 15 11:44 ./empty.txt
