Stream file ownership

My UNIX friend gave me notes in a different order:

- the owner, group, and PUBLIC are in same order
- read=4, write=2, execute=1

So umask 754 =

Owner = 7 = 4 + 2 + 1 (read + write + execute)
Group = 5 = 4 + 1 (read + execute)
Public = 4 (read)

A question that I never had answered: does this apply to stream files only, or
to database files, too? We have some utilities that read SAP files, and we want
to have PUBLIC have *USE authority on the DB files. But anything new created,
or after SE14 maintenance, I believe, PUBLIC is reset to *EXCLUDE.

Hi Rick,

I'm not a UNIX-Expert, but it is similar as described below:

077, 022, ...

All these are octal numbers. The first digit is the authority for the owner,
the second for the group of the owner and the third for *PUBLIC.
You have read (=1), write (=2) and execute (=4) (I hope this is the right
order?). When you want e.g. write and execute, you'd add 2 + 4 = 6

=> 022 means: for the group and everybody there is write-access.

Regards

Volker
