# You could replace the three items with whatever you need.
# "/usr/bin/fake_atos" is the thing to enable for 15 minutes only.
# "/usr/bin/atos" is the location at which ANY of these items is invoked. (by your compiler, or other process)
# "/usr/bin/REAL_atos" is the ORIGINAL exe to restore after 15 min.


cp /usr/bin/fake_atos /usr/bin/atos

# some mac osx security update made it so you must 'sudo' to run `at`
echo "cp /usr/bin/REAL_atos /usr/bin/atos" | sudo at now + 15 minutes

echo "real exe should be restored in 15 minutes."
echo "to restore it sooner, you can run this:"
echo "    cp /usr/bin/REAL_atos /usr/bin/atos"
