When I asked this question, someone posted something like this:
Prepare a directory hierarchy for group use, do the following as
root:
# chgrp -R $group $dir
# find $dir -type d -print0 | xargs -0 chmod 2770
(You can use mode 2775, depending on needs for further information see
'man chmod' and google on Linux permissions)
# sudo find $dir -type f -print0 | xargs -0 chmod 660
(likewise, you may also use mode 664...)
An alternative to the above is:
# sudo find $dir -type f -print0 | xargs -0 chmod g=u,o=-rwx
This will clear permissions for others and set group permissions to the
user permissions. This will preserve executable permissions. Give
yourself membership of the various groups to test permissions,
ownership, etc.
