If _l_i_m_i_t is given, it is the new value of the specified resource
(the --aa option is display only). If no option is given, then --ff
is assumed. Values are in 1024-byte increments, except for --tt,
which is in seconds, --pp, which is in units of 512-byte blocks,
and --nn and --uu, which are unscaled values. The return status is
0 unless an invalid option or argument is supplied, or an error
is assumed. Values are in 1024-byte increments, except for --tt,
which is in seconds, --pp, which is in units of 512-byte blocks,

occurs while setting a new limit.
uummaasskk [--pp] [--SS] [_m_o_d_e]
The user file-creation mask is set to _m_o_d_e. If _m_o_d_e begins with
a digit, it is interpreted as an octal number; otherwise it is
interpreted as a symbolic mode mask similar to that accepted by
_c_h_m_o_d(1). If _m_o_d_e is omitted, the current value of the mask is
printed. The --SS option causes the mask to be printed in sym-
bolic form; the default output is an octal number. If the --pp
a digit, it is interpreted as an octal number; otherwise it is
interpreted as a symbolic mode mask similar to that accepted by
_c_h_m_o_d(1). If _m_o_d_e is omitted, the current value of the mask is
printed. The --SS option causes the mask to be printed in sym-
bolic form; the default output is an octal number. If the --pp
option is supplied, and _m_o_d_e is omitted, the output is in a form
that may be reused as input. The return status is 0 if the mode
was successfully changed or if no _m_o_d_e argument was supplied,
was successfully changed or if no _m_o_d_e argument was supplied,
and false otherwise.

Remove each _n_a_m_e from the list of defined aliases. If --aa is

is true unless a supplied _n_a_m_e is not a defined alias.

For each _n_a_m_e, remove the corresponding variable or function.
If no options are supplied, or the --vv option is given, each _n_a_m_e
refers to a shell variable. Read-only variables may not be
unset. If --ff is specified, each _n_a_m_e refers to a shell func-
tion, and the function definition is removed. Each unset vari-
able or function is removed from the environment passed to sub-
sequent commands. If any of RRAANNDDOOMM, SSEECCOONNDDSS, LLIINNEENNOO, HHIISSTTCCMMDD,

wwaaiitt [_n _._._.]
Wait for each specified process and return its termination sta-

job spec is given, all processes in that job's pipeline are
waited for. If _n is not given, all currently active child pro-
cesses are waited for, and the return status is zero. If _n
specifies a non-existent process or job, the return status is
