How to change lvuser default permission when creating file

Hi,

 

I am currently working on a project using Linux R-T and I had some questions about the permissions when lvuser create a tdms file. I was wondering if it was possible to change the default permissions when a file is created because we want to be able to delete the files once they have been copied. 

 

Right now, the permissions are drwxr-xr-x for the directories and -r--rw-r-- for the files

 

I tried to change the umask in the profile but nothing change, same for setfacl

 

When I do a chmod, the files permissions changes but everytime one new file is created, I have to redo the chmod and I think it is not a good solution for the long term and I would like something that I have to configure only one time.

 

I am open to any solutions

 

Thank you!
