linux 命令提示符的设置

Linux shell is very powerful. Sometimes I use it. But the long command prompts make me uncomfortable.

This is my favorate command prompt:

export PS1="> "

PS1 is the environmental variable to set the command prompt of shell.

Off course, they are many other optional argument you can select.

argument	explaination
\d	date
\H	full hostname
\h	short hostname
\t	for 24 hours
\T	for 12 hours
\u	user name
\w	the full path
\W	the last full dir name
#	the number of the command

Example:

export PS1="\#"
25
export PS1="\W \u \t"
~ zhulin 22:32:49
export PS1="\H \w \u"
DESKTOP-RGJAM13 ~ zhulin
