- 让所有用户的PATH环境变量的值多出一个路径，例如：/usr/local/apache/bin
[root@localhost ~]# cat /etc/profile.d/path.sh
#!/bin/bash
PATH=$PATH:/usr/local/apache/bin
- 用户 root 登录时，将命令指示符变成红色，并自动启用如下别名：
rm=‘rm –i’
cdnet=‘cd /etc/sysconfig/network-scripts/’
editnet=‘vim /etc/sysconfig/network-scripts/ifcfg-eth0’
editnet=‘vim /etc/sysconfig/network-scripts/ifcfg-eno16777736 或 ifcfg-ens33 ’ (如果系统是CentOS7)
[root@localhost ~]$echo 'PS1="\e[1;31m\][\u@\h \W]\$\e[0m\]"' >> ~/.bashrc
[root@localhost ~]$. .bashrc
[root@localhost ~]# cat .bashrc
# .bashrc
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
alias free="free -h"
alias cdnet="cd /etc/sysconfig/network-scripts/"
alias editnet='vim /etc/sysconfig/network-scripts/ifcfg-eth0'
- 任意用户登录系统时，显示红色字体的警示提醒信息“Hi,dangerous！”
[root@localhost ~]# cat /etc/profile.d/env.sh
#!/bin/bash
echo -e '\033[1;31m Hi,dangerous! \033[0m'
- 编写生成脚本基本格式的脚本，包括作者，联系方式，版本，时间，描述等
[root@localhost ~]# cat .vimrc
set et
set ts=4
autocmd BufNewFile *.sh exec ":call SetTitle()"
func SetTitle()
if expand("%:e") == 'sh'
call setline(1,"#!/bin/bash")
call setline(2,"#")
call setline(3,"#********************************************************************")
call setline(4,"#Author: Richard")
call setline(5,"#QQ： 41668690")
call setline(6,"#Email： 41668690@qq.com")
call setline(7,"#Date: " .strftime('%Y-%m-%d'))
call setline(8,"#FileName： " .expand('%'))
call setline(9,"#URL: underdefine")
call setline(10,"#Version： underdefine")
call setline(11,"#Description： underdefine")
call setline(12,"#Copyright: " .strftime("%Y")." All rights reserved")
call setline(13,"#********************************************************************")
call setline(14,"")
endif
endfunc
