Command line Administration limits??

I must state explicitly that I do not care about the GUI tools. ?No real administrator of systems capable of handling thousands of users will ever care about the GUI tools. I appreciate apples limited documentation, but it doesn't address everything I would need to have done. ?The 'adding a user', 'modifying a user', and 'deleting a user' are covered. ?But at no time have I found what I need to be able to explicitly: ????Create a user ????Create their home directory ????Set their disk quota ????Set their email quota ????Modify a users disk quota ????Modify a users email quota ????Modify a users name, adjust home directories and mail ????????configuration to match new account parameters. ????Delete a users disk quota ????Delete a users email quota ????Delete a users account have it automatically remove their ????????quotas, home directories, and files included therein. All from the command line. ?I am more than capable of writing scripts if I need to run multiple commands for each, finding those commands via OS X has not been easy. ?I know how to 'make a directory'. ?I do not know how, in the OS X way of doing things, how to do the rest. That is the part that stumped me and used up most of my time for a project I am working on I know how to: ????Create a user in OpenDirectory. ????Change a users password in OpenDirectory. ????Change a users 'gecos' or full name in OpenDirectory. ????Change a users login name in OpenDirectory. ????Delete a user in OpenDirectory. Anyone have a better reference than apples standard docs? Thanks in advance
