Linux如何设置命令提示字符

Linux如何设置命令提示字符
使用echo $PS1命令查看prompt字符
[root@golonglee ~]# echo $PS1
[\u@\h \W]$
[root@golonglee ~]#
在/etc/inittab文件中可以是初始化列表
这是vi /etc/bashrc文件的内容
# /etc/bashrc
# System wide functions and aliases
# Environment stuff goes in /etc/profile
# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.
# are we an interactive shell?
if [ "$PS1" ]; then
if [ -z "$PROMPT_COMMAND" ]; then
case $TERM in
xterm*)
if [ -e /etc/sysconfig/bash-prompt-xterm ]; then
PROMPT_COMMAND=/etc/sysconfig/bash-prompt-xterm
else
PROMPT_COMMAND='printf "3]0;%s@%s:%s
