1、使用echo $PS1命令查看prompt字符[root@golonglee ~]# echo $PS1[\u@\h \W]\$[root@golonglee ~]#
2、在/etc/inittab文件中可以是初始化列表
3、这是vi /etc/水瑞侮瑜bashrc文件的内容# /etc/bashrc# System wide fun艘早祓胂ctions and aliases# Environment stuff goes in /etc/profile# It's NOT a good idea to change this file unless you know what you# are doing. It's much better to create a custom.sh shell script in# /etc/profile.d/ to make custom changes to your environment, as this# will prevent the need for merging in future updates.# are we an interactive shell?if [ "$PS1" ]; then if [ -z "$PROMPT_COMMAND" ]; then case $TERM in xterm*) if [ -e /etc/sysconfig/bash-prompt-xterm ]; then PROMPT_COMMAND=/etc/sysconfig/bash-prompt-xterm else PROMPT_COMMAND='printf "\033]0;%s@%s:%s\007" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"' fi ;; screen) if [ -e /etc/sysconfig/bash-prompt-screen ]; then PROMPT_COMMAND=/etc/sysconfig/bash-prompt-screen else PROMPT_COMMAND='printf "\033]0;%s@%s:%s\033\\" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"' fi ;; *) [ -e /etc/sysconfig/bash-prompt-default ] && PROMPT_COMMAND=/etc/sysconfig/bash-prompt-default ;; esac fi # Turn on checkwinsize shopt -s checkwinsize [ "$PS1" = "\\s-\\v\\\$ " ] && PS1="[\u@\h \W]\\$ "
4、编辑etc目录下的bashrc文件，可以修改提示符
5、如果以上经验帮到您，麻烦在左下角给点个赞，谢谢！
6、这是/etc/inittab文件的内容[root@golonglee ~]# cat /etc/inittab# inittab is o荏鱿胫协nly used by upstart for the default runlevel.## ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.## System initialization is started by /etc/init/rcS.conf## Individual runlevels are started by /etc/init/rc.conf## Ctrl-Alt-Delete is handled by /etc/init/control-alt-delete.conf## Terminal gettys are handled by /etc/init/tty.conf and /etc/init/serial.conf,# with configuration in /etc/sysconfig/init.## For information on how to write upstart event handlers, or how# upstart works, see init(5), init(8), and initctl(8).## Default runlevel.
