limit [ -hs ] [ resource [ limit ] ] ...
       Set  or  display  resource limits.  Unless the -s flag is given,
       the limit applies only the children of  the  shell.   If  -s  is
       given  without  other arguments, the resource limits of the cur-
       rent shell is set to the previously set resource limits  of  the
       children.

       If  limit  is  not  specified, print the current limit placed on
       resource, otherwise set the limit to the  specified  value.   If
       the  -h  flag  is given, use hard limits instead of soft limits.
       If no resource is given, print all limits.

       resource can be one of:

       addressspace
              Maximum amount of address space used.
       aiomemorylocked
              Maximum amount of memory locked in  RAM  for  AIO  opera-
              tions.
       aiooperations
              Maximum number of AIO operations.
       cachedthreads
              Maximum number of cached threads.
       coredumpsize
              Maximum size of a core dump.
       cputime
              Maximum CPU seconds per process.
       datasize
              Maximum data size (including stack) for each process.
       descriptors
              Maximum value for a file descriptor.
       filesize
              Largest single file allowed.
       maxproc
              Maximum number of processes.
       maxpthreads
              Maximum number of threads per process.
       memorylocked
              Maximum amount of memory locked in RAM.
       memoryuse
              Maximum resident set size.
       resident
              Maximum resident set size.
       sockbufsize
              Maximum size of all socket buffers.
       stacksize
              Maximum stack size for each process.
       vmemorysize
              Maximum amount of virtual memory.

       Which of these resource limits are available depends on the sys-
       tem.  resource can be abbreviated to any unambiguous prefix.

       limit is a number, with an optional scaling factor, as follows:

       nh     hours
       nk     kilobytes (default)
       nm     megabytes or minutes
       [mm:]ss
              minutes and seconds
