- 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'.

- _-_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.
