Heh... Well, you need to know the protection system in RSX...


Yeah.   I'm skimming the Manager's guide (which doesn't actually have the
commands.   Seriously.   There are blank spaces where the command should be)

I think you've found a scan where anything in red turned invisible. There are other scans of the manuals that are better.

File protection is totally unrelated to the terminal privilege status.
File protection comes in four categories.
System - Any access from a group <=10 (octal)
Owner - Should be obvious
Group - Matching group but not member
World - Everybody else

So, in your case, either having a UIC of [131,54] or any system UIC
should have done it. Maybe any member of 131 as well.
[137,10] means you'll fall under the WORLD mask.


Ahhhhhhh.   That makes much more sense, thanks!

It all makes sense, once you know it. :-)

The terminal privilege status on the other hand allows you to change
your terminal UIC to anything you want. If you are unprivileged, you
cannot change your UIC.

Ahhhhhhhh.   I was thinking of it in VMS terms.

Hmm. Terminals are not privileged under VMS, I thought. I though it was users who have various privileges.

And then, of course, tasks can be installed to run under another UIC
than your terminal UIC...
But installing tasks also requires that your terminal is privileged...


Good thing I've not managed to make the console unprivileged. ;)

Yes. If you make it non-privileged, you will not be able to turn it back to privileged again, since that is a privileged command... :-)
However, by default, the system manager account has the password "SYSTEM" if I remember right. And that leaves you logged in with privileges...
