General question about Linux

[William F. Acker WB2FLW +1-303-777-8123]

Thomas: I think that 755 is what you would have said if you had taken the
time to experiment before you posted.  744 is useless!  Others can sort of
list the files, but they can't get to them.  In most cases, 5 is what you
need for the group or others to allow folks other than the owner to get at
the files, but not add or delete any.  What they can do with them depends
on the permissions of the individual file.  If you want to allow someone
to access a file only if they know its name, then 1 is the digit to use.  
BTW, Teddy, the word here is permissions, *not* rights.  Rights is a
windows term, permissions is the correct Unix term.
