CentOS - Nov 2004 - File permission

Hello all,

  I think my file permission are completely screwed up?  I created a 
file called text file called test as root user and have done chgrp on 
that file to a group called admin.  I have added the users ozzie and 
root to that group.  I then did a chmod g+wr on the test file and ozzie 
can still not write to the file.  If I take away read access from the 
group, ozzie can still read the file.  The group permissions have no 
effect what so ever.  If you add or take away permissions from the other 
permissions, that will effect the test file.   What did I do wrong?  
Could someone please point me in the right direction?

Thanks all.

Dominic

I don't think I was really going to get an answer for this anyway but, I 
figured it out. After making my change I logged out and back in again 
and it worked. I think I get it but if someone could explain it to me 
that would be nice.

Thanks

In very simple terms, if you add someone to a group, until they
re-authenticate, i.e. logout & login again, the new permissions will not be
seen by said user.

Simple is very good for me.

I definitely understand this.

Thanks :)
