.Sh DESCRIPTION
.Nm
executes
.Ar utility
after modifying the environment as
specified on the command line.  The option
.Ar name Ns No = Ns Ar value
specifies
an environment variable,
.Ar name  ,
with a value of
.Ar value  .
The
.Fl i
option
causes
.Nm
to completely ignore the environment
it inherits.
.Pp
If no
.Ar utility
is specified,
.Nm
prints out the names and values
of the variables in the environment, with one
.Ar name Ns No = Ns Ar value
pair per line.
.Sh DIAGNOSTICS
If the
.Ar utility
is invoked, the exit status of
.Nm
shall be the exit status of
.Ar utility ;
otherwise, the
.Nm
utility exits with one of the following values:
.Bl -tag -width Ds
.It 0
The
.Nm
utility completed successfully.
