在prompt字串做變化:

另一範例: export PS1='n u@h e[32m W e[0m'

Color	Foreground	Background
Black	30	40
Red	31	41
Green	32	42
Yellow	33	43
Blue	34	44
Magenta	35	45
Cyan	36	46
White	37	47

PS1 提示符號的完整說明必須用man bash來查詢; 但bash的內容太多了, 不易瀏覽, 由Google找到

查詢man指令的網站: http://www.mediacollege.com/linux/man/index.html

可以顯示得較容易觀看. PS1的變更要找其內的PROMPTING, 特殊字元如下:
