DESCRIPTION
If you call env with no arguments, it displays the environment that it received from its parent
(presumably the shell).

let you add new variables or change the value of existing variables of the environment.
If you specify command, env calls command with the arguments that appear on the command
line, passing the accumulated environment to this command. The command is executed
directly as a program found in the search
PATH , and is not interpreted by a shell.
