The way to achieve group collaboration is to have new files and
directories
become the group name of the group, not the default group name of the
creator. Also, new files and directories need to have the group's
write bit set. Here are the commands:
1) sudo chmod g+wxs .
2) sudo chgrp psacln .
3) sudo echo "umask 0002" >> /etc/profile
The key is the s-bit set on the directory. This has the special meaning
of setting new files' and directories' group name to the group name
of the directory, not the creator.
The umask command says to always turn on the group's write bit for new
files and directories.
All of the users are members of the group psacln and when they create files or upload them via FTP, the files have the correct group assignment. However, even after going through the steps you outlined above, new files are not created with the proper permissions. When I FTP test.test with Rita's account, the file has permissions -rw-r--r-- set. I need it to be -rw-rw-r-- so that, say, Robin can edit or even overwrite test.test.
