I've got a development Ubuntu system for which I have several users: myself (with full sudo) and about 5 other users. (I've set up the system so everything in this respect is still at its default setting)

I'm trying to set the system up so that multiple people can collaborate in a single directory by using grouing and I want the default permissions to be 664. However when some users edit files the permissions were 644.

After a lot of investigating most users have a umask (checked at the prompt) of 0002 and when they create files they are 664 (as expected) but there are 2 (myself and one other) who have 0022 umask (so the files that come out are 644 and nobody else can write to them).

I've looked everywhere but can't figure out why a couple users wind up with a different umask e.g. there is nothing the .bash_profile or anything like that)

Any ideas for the source of the discrepancy?

/etc/bashrc

if [ $UID -gt 199 ] && [ "`id -gn`" = "`id -un`" ]; then
   umask 002
else
   umask 022
fi

/etc/profile

if [ $UID -gt 199 ] && [ "`id -gn`" = "`id -un`" ]; then
    umask 002
else
    umask 022
fi

EDIT:

My (bad) ~/.bashrc

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
    . /etc/bashrc
fi

# User specific aliases and functions


export LANG=en_US.utf8

Other user (good) .bashrc

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
    . /etc/bashrc
fi

# User specific aliases and functions
