SYNOPSIS
       env [OPTION]... [-] [NAME=VALUE]... [COMMAND [ARG]...]

DESCRIPTION
       Set each NAME to VALUE in the environment and run COMMAND.

       Mandatory arguments to long options are mandatory for short options too.

       -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
