In order to change the umask for a user you can use the following command:

sudo chfn -o umask=007 username

Experiment with the umask value in order to suit your needs :)

You can try ~/.bashrc beside ~./profile.

sudo nano /home/user/.bashrc

Add line:

umask 002

Save file, exit and try again.

Also you can try to execute command as another user:

su -c "command" user

In your case:

su -c "umask 002" user

I’ve just edited .bashrc logged in with ftp as the user and uploaded a file and it still gets created as 755 rather than 775.

Presumably it’s something to do with the fact that it’s using ftp rather than ssh/bash, although I don’t really understand the way in which the two are different/similar.

Hi, robjbrain. If you’re root, i think you can resolve your situation creating a file in /etc/profile.d/with this code:

userumask=$(id -un)
if [ "$userumask" = "user-of-your-interes" ]; then
        umask 033 ; or the umask you want to that user
fi

/etc/profile calls the files in /etc/profile.d/ after setting umask with default rules, so your custom rule would take effect. I resolve a similar case with this code, but there is no clear documentation for this use cases.
