ACLs and standard file permissions seem to be synchronized:
$ getfacl test.cpp # file: test.cpp # owner: scdmb # group: scdmb user::rw- group::rw- other::r-- $ ls -l test.cpp -rw-rw-r-- 2 scdmb scdmb 173 Jan 1 1970 test.cpp
However as I've read there are two locations in inode to save file permissions (i_mode field) and these extended file attributes where ACLs are placed. So when I access file then which file permissions are used – standard or ACLs? Or maybe this is the same thing presented in different ways?
