Err, ulimit is part of bash, run 'man bash' and search for ulimit.
--=20
ulimit [-SHacdflmnpstuv [limit]]
Provides control over the resources available to
the shell and to processes started by it, on sys=AD
tems that allow such control. The -H and -S
options specify that the hard or soft limit is set
for the given resource. A hard limit cannot be
increased once it is set; a soft limit may be
increased up to the value of the hard limit. If
neither -H nor -S is specified, both the soft and
hard limits are set. The value of limit can be a
number in the unit specified for the resource or
one of the special values hard, soft, or unlimited,
which stand for the current hard limit, the current
soft limit, and no limit, respectively. If limit
is omitted, the current value of the soft limit of
the resource is printed, unless the -H option is
given. When more than one resource is specified,
the limit name and unit are printed before the
value. Other options are interpreted as follows:
-a All current limits are reported
-c The maximum size of core files created
-d The maximum size of a process's data segment
-f The maximum size of files created by the
shell
-l The maximum size that may be locked into
memory
-m The maximum resident set size
-n The maximum number of open file descriptors
(most systems do not allow this value to be
set)
-p The pipe size in 512-byte blocks (this may
not be set)
-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 avail=AD
able to the shell
If limit is given, it is the new value of the spec=AD
ified resource (the -a option is display only). 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,
and -n and -u, which are unscaled values. The
return status is 0 unless an invalid option or
argument is supplied, or an error occurs while set=AD
ting a new limit.
