Hi Patrick.

Unix permissions work like this:

1 - execute (or traverse if a directory)
2 - write
4 - read

further.. the groupings are 

owner group others

so 755 = rwxr-xr-x

Read/Write/Execute for owner
Read and Execute for owner's groups and Others

so for someone random (i.e. everyone) to get into a directory, it would need at least

d--------x

now... they won't be able to list files.. that needs  r-x

The utility to change permissions is chmod


chmod -R 755 michael.users testdir

means that I want to assign rwxr-xr-x to testdir AND everything below it  (-R is recurse)
