       This manual page documents the GNU version  of  eennvv.   eennvv
       runs  a	command with an environment modified as specified
       by the command line  arguments.	Arguments  of	the  form
       `variable=value'	set the environment variable _v_a_r_i_a_b_l_e to
       value _v_a_l_u_e.  _v_a_l_u_e may be empty (`variable=').	Setting a
       variable to an empty value is different from unsetting it.

       The  first  remaining  argument	specifies  a  program  to
       invoke;	it is searched for according to the specification
       of the PATH environment variable.  Any arguments following
       that are passed as arguments to that program.

       If  no command name is specified following the environment
       specifications,	the  resulting	environment  is	printed.
       This is like specifying a command name of `printenv'.

   OOPPTTIIOONNSS
       _-_u_, _-_-_u_n_s_e_t _n_a_m_e
	      Remove  variable	_n_a_m_e  from the environment, if it
	      was in the environment.

       _-_, _-_i_, _-_-_i_g_n_o_r_e_-_e_n_v_i_r_o_n_m_e_n_t
	      Start  with  an  empty  environment,  ignoring  the
	      inherited environment.

       The  long-named options can be introduced with `+' as well
       as `--', for compatibility with previous releases.   Even-
       tually  support	for  `+'  will	be removed, because it is
       incompatible with the POSIX.2 standard.
