Linux如何設置命令提示字符

  Linux中支持自定義command的prompt字符,但是有很多LINUX操作系統(tǒng)的新手并不知道如何使用,不過沒關系,學習啦小編在本文就給大家介紹下了如何設置命令提示字符。

  Linux如何設置命令提示字符

  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

  這是vi /etc/bashrc文件的內(nèi)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

  # Turn on checkwinsize

  shopt -s checkwinsize

  [ "$PS1" = "\s-\v\$ " ] && PS1="[\u@\h \W]\$ "

  編輯etc目錄下的bashrc文件,可以修改提示符
