Ok heres the situation
I've been studying Solaris 8 for about 6 months now and some things click in my head but others don't.
One of the things that don't click are file permissions.
For example I login at work and I use the ls -l command to get a long listing of the files w/ the permissions.

What does -r-xr-xr-x mean???
I understand a little about world, group and user but I need it explained in laymens terms

Please help, any info you could spare would be much appreciated
