description

Set each NAME to VALUE in the environment and run COMMAND.
-i, --ignore-environment

start with an empty environment

-0, --null

end each output line with 0 byte rather than newline

-u, --unset=NAME

remove variable from the environment

--help

display this help and exit

--version

A mere - implies -i. If no COMMAND, print the resulting environment.
