In each of the following opts, n may be =, indicating that the soft limit should be set equal to the hard limit.

opts controlling memory use:

-m n Same as -d n -s n -l n -a n.
-d n Limit the data segment per process to n bytes.
-s n Limit the stack segment per process to n bytes.
-l n Limit the locked physical pages per process to n bytes. This option has no effect on some operating systems.
-a n Limit the total of all segments per process to n bytes. This option has no effect on some operating systems.
-o n Limit the number of open file descriptors per process to n. This option has no effect on some operating systems.
-p n Limit the number of processes per uid to n.
opts controlling file sizes:
-f n Limit output file sizes to n bytes.
-c n Limit core file sizes to n bytes.

-r n Limit the resident set size to n bytes. This limit is not enforced unless physical memory is full.
-t n Limit the CPU time to n seconds. This limit is not enforced except that the process receives a SIGXCPU signal after n seconds.
