|A||max address space (KB)|
|C||max core file size (KB)|
|D||max data size (KB)|
|F||maximum file size (KB)|
|M||max locked-in-memory address space (KB)|
|N||max number of open files|
|R||max resident set size (KB)|
|S||max stack size (KB)|
|T||max CPU time (MIN)|
|U||max number of processes|
|P||process priority -20..20 (negative = high priority)|
