/usr/bin/chown john /home/john/*
!/usr/bin/chown john /home/john/*..*
!/usr/bin/chown john /home/john/* *
You can do something similar for chmod, but it depends on what they
need. For example:
/usr/bin/chmod g+r,o+r /home/john/*
!/usr/bin/chmod g+r,o+r /home/john/*..*
!/usr/bin/chmod g+r,o+r /home/john/* *
Be careful. A combination of sudo's for chmod and chown set too widely
can easily lead to a root shell.
