Answer 3

只需在終端執行env。

輸出示例：

$ 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
