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 current 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.

       When looping over  multiple  resources,  the  shell
       will abort immediately if it detects a badly formed
       argument.  However, if it fails to set a limit  for
       some  other  reason  it will continue trying to set
       the remaining limits.

       resource can be one of:

       addressspace
              Maximum amount of address space used.
       aiomemorylocked
              Maximum amount of memory locked in  RAM  for
              AIO operations.
       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 system.  resource can be abbreviated
       to any unambiguous prefix.  It can also be an inte-
       ger,  which  corresponds to the integer defined for
       the resource by the operating system.

       If argument corresponds to a number which is out of
       the  range  of  the  resources  configured into the
       shell, the shell will try  to  read  or  write  the
       limit  anyway,  and  will  report  an error if this
       fails.  As the shell does not store such  resources
       internally,  an  attempt to set the limit will fail
       unless the -s option is present.

       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
