Data User Access Rights

Hi Folks,

My problem is an easy one for the experts here. All my applications run using a user id that creates files with only the following default rights:
-rw-r-----

I want to modify this user's account such that it creates files that assign read access to the everyone group by default:
-rw-r--r--

Can someone help with this?

Thanks and Regards,
Umair.

Hi.

Yes, you can do this by changing the "umask".

For rw-r--r--, the umask should be 133:

Code:
umask 133
touch x
ll x
-rw-r--r--    1 me mygroup              0 Aug 25 12:22 x

See the man page for more information.

Hi Umair,

It goes like this:

You want the default permissions 644.

So you need to give umask with the option 777-644 i.e 133

umask 133

Cheers,
Shazin

I would suggest using umask 022 instead. Otherwise newly created directories will get invalid permissions and will not be accessible.

I used umask 022 as it is the recommended option for the read access rights I needed to grant to other users.

Hi Folks,

That solution only works while I am logged in and I start the application using my login. I have the umask 022 command in my .bashrc file too. When the application is started using the Cron (using my user), this property seems to disappear. How do I make this permanent?


Thanks,
Umair.
