different umask for different user


I have this profile script right now...

#/etc/profile

if [ `id -gn` = `id -un` -a `id -u` -gt 14 ]; then
umask 002
else
umask 022
fi

How do I make it so that user "mm4" has a umask of 002 without messing up the original security permissions? Rigth now every file that is created within mm4's directory has permissions of 600 and I need them to be 775. Thanks

Okay, maybe I was dealing with the wrong thing. I don't really log in. The web server is running all the time and there is a folder (users/mm4) that whenever files are put in it or created in it by software running on the server, their default permission is 600. I called the software company and they said it was cause my default permissions for that folder were set to 600 so anything created in there would have those permissions. Thats when I thought it was a umask issue but I guess I was wrong. How do I set default permissions for a certain folder??

Umasks aren't given to dirs, but to users and groups.

Simple example: umask 077; mkdir TEST: TEST would be created with rights 700. Now
umask 002; touch TEST/test; ls -al TEST.
Now it'll return permissions as 0664 on TEST/test, because the user mask is now 002, even tho the dir's permissions where set to 0700.

So you could set the user mask to 007 if you would allow default file creation to be set to user and group read-write and world none. *Note this doesn't prevent manual chmodding it to 0777 by user or group members.

HTH somehow
