	53	.Sh DESCRIPTION
	54	.Nm
	55	executes
	56	.Ar utility
	57	after modifying the environment as
	58	specified on the command line. The option
	59	.Ar name=value
	60	specifies
	61	an environmental variable,
	62	.Ar name ,
	63	with a value of
	64	.Ar value .
	65	The option
	66	.Sq Fl i
	67	causes
	68	.Nm
	69	to completely ignore the environment
	70	it inherits.
	71	.Pp
	72	If no
	73	.Ar utility
	74	is specified,
	75	.Nm
	76	prints out the names and values
	77	of the variables in the environment, with one
	78	.Ar name=value
	79	pair per line.
	80	.Sh DIAGNOSTICS
	81	If the
	82	.Ar utility
	83	is invoked, the exit status of
	84	.Nm
	85	shall be the exit status of
	86	.Ar utility;
	87	otherwise, the
	88	.Nm
	89	utility exits with one of the following values:
	90	.Bl -tag -width Ds
	91	.It 0
	92	The
	93	.Nm
	94	utility completed successfully
	95	.It 1-125
	96	An error occurred in the
	97	.Nm
	98	utility.
	99	.It 126
	100	The utility specified by
	101	.Ar utility
	102	was found, but could not be invoked.
	103	.It 127
	104	The utility specified by
	105	.Ar utility
	106	could not be found.
	107	.El
	108	.Sh COMPATIBILITY
	109	The historic
	110	.Fl
	111	option has been deprecated but is still supported in this implementation.
	112	.Sh SEE ALSO
	113	.Xr execvp 3 ,
	114	.Xr environ 7
	115	.Sh STANDARDS
	116	The
	117	.Nm
	118	utility conforms to
	119	.St -p1003.2-92 .
	120	.Sh BUGS
	121	.Nm
	122	doesn't handle commands with equal
	123	.Pq Dq =
	124	signs in their
	125	names, for obvious reasons.
