Linux中支持自定义command的prompt字符，但是有很多LINUX操作系统的新手并不知道如何使用，不过没关系，小编在本文就给大家介绍下了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 "33]0;%s@%s:%s07" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"'

fi

;;

screen)

if [ -e /etc/sysconfig/bash-prompt-screen ]; then

PROMPT_COMMAND=/etc/sysconfig/bash-prompt-screen

else

PROMPT_COMMAND='printf "33]0;%s@%s:%s33\" "${USER}" "${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]\$ "

编辑etc目录下的bashrc文件，可以修改提示符
