umask & dot forward

775 would give you rwxrwxr-x, which does not give "everyone" write
perms.  You'd want 776 (or 777 if you want them to be able to execute
it.)

4 digit mask includes (first digit) special bits, such as 'd' 't' 's',
Which are all explained quite well in the chmod man page.

The UMASK is the inverse of permissions.  Basically if you have a UMASK
of 022 then those bits are subtracted from a normal bitmask.  Like so:

UMASK = 022 == Permissions = 755

Hope that helps.
