Once that is done, here are some functions that I wrote to help manage these ACLs.

Here is an example of a command that grants apache permission to read a directory with these functions:

> source aclfunctions.bash; grantUserRead 'apache' /var/www '*';

aclfunctions.bash:

function resetAll
{
   echo "Resetting permissions on all files in directory $1";

   echo "Removing ACLs...";
   setfacl -Rb $1;

   echo "Resetting directories...";
   find $1 -type d -exec chmod 770 {} \;

   echo "Resetting files...";
   find $1 -type f -exec chmod 660 {} \;
