Details

Excerpt from:   Bash source   >>   ulimit command

Possible #if / #endif blocks are compile options. There is no mechanism yet on BoxMatrix to detect which of these are set per model.

ulimit [-SHabcdefiklmnpqrstuvxPT] [limit]

Modify shell resource limits.

Provides control over the resources available to the shell and processes
it creates, on systems that allow such control.

Options:
  -S    use the `soft' resource limit
  -H    use the `hard' resource limit
  -a    all current limits are reported
  -b    the socket buffer size
  -c    the maximum size of core files created
  -d    the maximum size of a process's data segment
  -e    the maximum scheduling priority (`nice')
  -f    the maximum size of files written by the shell and its children
  -i    the maximum number of pending signals
  -k    the maximum number of kqueues allocated for this process
  -l    the maximum size a process may lock into memory
  -m    the maximum resident set size
  -n    the maximum number of open file descriptors
  -p    the pipe buffer size
  -q    the maximum number of bytes in POSIX message queues
  -r    the maximum real-time scheduling priority
  -s    the maximum stack size
  -t    the maximum amount of cpu time in seconds
  -u    the maximum number of user processes
  -v    the size of virtual memory
  -x    the maximum number of file locks
  -P    the maximum number of pseudoterminals
  -T    the maximum number of threads

Not all options are available on all platforms.

If LIMIT is given, it is the new value of the specified resource; the
special LIMIT values `soft', `hard', and `unlimited' stand for the
current soft limit, the current hard limit, and no limit, respectively.
Otherwise, the current value of the specified resource is printed.  If
no option is given, then -f is assumed.

Values are in 1024-byte increments, except for -t, which is in seconds,
-p, which is in increments of 512 bytes, and -u, which is an unscaled
number of processes.

Exit Status:
Returns success unless an invalid option is supplied or an error occurs.

Excerpt from:   bashref.info   >>   Bash Builtins   >>   ulimit command

ulimit [-HSabcdefiklmnpqrstuvxPT] [LIMIT]

'ulimit' provides control over the resources available to processes
started by the shell, on systems that allow such control.  If an
option is given, it is interpreted as follows:

-S
     Change and report the soft limit associated with a resource.

-H
     Change and report the hard limit associated with a resource.

-a
     All current limits are reported.

-b
     The maximum socket buffer size.

-c
     The maximum size of core files created.

-d
     The maximum size of a process's data segment.

-e
     The maximum scheduling priority ('nice').

-f
     The maximum size of files written by the shell and its
     children.

-i
     The maximum number of pending signals.

-k
     The maximum number of kqueues that may be allocated.

-l
     The maximum size that may be locked into memory.

-m
     The maximum resident set size (many systems do not honor this
     limit).

-n
     The maximum number of open file descriptors (most systems do
     not allow this value to be set).

-p
     The pipe buffer size.

-q
     The maximum number of bytes in POSIX message queues.

-r
     The maximum real-time scheduling priority.

-s
     The maximum stack size.

-t
     The maximum amount of cpu time in seconds.

-u
     The maximum number of processes available to a single user.

-v
     The maximum amount of virtual memory available to the shell,
     and, on some systems, to its children.

-x
     The maximum number of file locks.

-P
     The maximum number of pseudoterminals.

-T
     The maximum number of threads.

If LIMIT is given, and the '-a' option is not used, LIMIT is the
new value of the specified resource.  The special LIMIT values
'hard', 'soft', and 'unlimited' stand for the current hard limit,
the current soft limit, and no limit, respectively.  A hard limit
cannot be increased by a non-root user once it is set; a soft limit
may be increased up to the value of the hard limit.  Otherwise, the
current value of the soft limit for the specified resource is
printed, unless the '-H' option is supplied.  When setting new
limits, if neither '-H' nor '-S' is supplied, both the hard and
soft limits are set.  If no option is given, then '-f' is assumed.
Values are in 1024-byte increments, except for '-t', which is in
seconds; '-p', which is in units of 512-byte blocks; '-P', '-T',
'-b', '-k', '-n' and '-u', which are unscaled values; and, when in
POSIX Mode (*note Bash POSIX Mode::), '-c' and '-f', which are in
512-byte increments.

The return status is zero unless an invalid option or argument is
supplied, or an error occurs while setting a new limit.
