Any program or script that is using it in such a way is broken and should be corrected. That's not true, -A displays the apparent size not the actual disk usage which is what we want. Disk usage is not equal to file size. 'ls -al' shows file size, 'du' shows disk usage. Use the one you need, but don't expect them to be the same thing. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D This e.mail is private and confidential between Multiplay (UK) Ltd. and the person or entity to whom it is addressed.
