Retaining Permissions During File Save

[jmarkus]

Hello,

My default permissions are 664. This allows other people in my group to work on and save files which I work on. I have one file, however, that needs to be soley under my control. That is, I want the permissions to be 644. Unfortunately, when I save that file, the permissions revert back to my default permission.

Is there any way I can set the permissions of this file so that even after saving it from an application, the desired permissions stay intact?

Thanks,
Jeff

664 is -rw-rw-r--

Yes, I am talking about umask (when referring to default permissions), but I don't want to change for all files, I only want to protect 1 file.

umask is not the problem in this case

User Commands                                            umask(1)

NAME
     umask - get or set the file mode [b]creation[/b] mask

what editor do you use to edit this file? does it just write and close? You can debug this by using truss

eg. truss -o /tmp/mytrussfile.out editor filename

next just close the file and look at the /tmp/mytrussfile.out...

I'm not suggesting umask is the problem. I am simply looking for a way to protect a file so that it doesn't revert to the default permissions after saving.

This is not a text file. It is a data file from an Engineering Design application (CAD).

Thanks,

I think it's an application fault; if you open a file eg. in vi it does not change access rights.
You can write a workaround: chmod filename with cron ;-)
