Answer 2

只需在终端中执行env。

示例输出：

$ env
TERM=xterm
SHELL=/bin/bash
USER=joksnet
USERNAME=joksnet
DESKTOP_SESSION=gnome
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
PWD=/home/joksnet
GDM_KEYBOARD_LAYOUT=us
LANG=en_US.utf8
HOME=/home/joksnet
DISPLAY=:0.0
COLORTERM=gnome-terminal
_=/usr/bin/env

Answer 3

输入export，不带任何参数。
