Re: Read-only dir & files within?

Well I read https://en.wikipedia.org/wiki/Chmod
If I did
qsh
chmod 775 /home/ROB/JT
this basically gave me the first digit 4(read) + 2(write) +1(execute) = 7
The group I belong to the second digit 4(read) + 2(write) +1(execute) = 7
and *public the third digit 4(read) + 1(execute) = 5

Which can easily be done with the IBM i Command GRTAUT
Either way you end up with
Data --Object Authorities--
User Authority Exist Mgt Alter Ref
*PUBLIC *RX X X X X
-------------Data Authorities-------------
Objopr Read Add Update Delete Execute
X X X

When I ran qsh's chmod 777 /home/ROB/JT
DUMMY can do create files in that directory
and you end up with
Data --Object Authorities--
User Authority Exist Mgt Alter Ref
*PUBLIC *RWX X X X X
-------------Data Authorities-------------
Objopr Read Add Update Delete Execute
X X X X X X

Six of one, half a dozen of another. At least you know that that an
attribute was the wrong thing to be looking for. It was the security
instead.
Then the user DUMMY could not create a new file in that directory

This sort of thing is an antipattern in our community.

Learn to use Unix permissions and permission commands for stream files in
the IFS.

Only bring OS/400 commands and notions of authorities if there is a
genuine use case ...

An' I tells youse peoples, there be precious few genuine use cases for
that.

Subject: Re: Read-only dir & files within?

I do not find any documentation on this. However this testing may answer
that:

MD DIR('/home/ROB/JT')

Directory created.

CHGATR OBJ('/home/ROB/JT') ATR(*READONLY) VALUE(*YES)

Attributes changed for 1 objects. 0 objects not changed.

EDTF STMF('/home/ROB/JT/test.txt')

The EDTF did create the file

DSPF STMF('/home/ROB/JT/test.txt')

The DSPF showed the changes.

There is an attribute called *RSTDRNMUNL you might want to read up on.

If a directory is marked read-only, can you still create & delete files
