SHELL脚本编程和文件软件包管理工具
作者:互联网
1、编写脚本 createuser.sh,实现如下功能:使用一个用户名做为参数,如果 指定参数的用户存在,就显示其存在,否则添加之;显示添加的用户的id号等信息
[root@centos8 data]# vim createuser.sh
#!/bin/bash

#******************************************************
set -ue
NAME=$1
id $NAME &> /dev/null && echo "$NAME is exist" || { useradd "$NAME";echo "$NAME is created";echo "id $NAME";id "$NAME"; }
[root@centos8 data]# chmod +x createuser.sh
[root@centos8 data]# ./createuser.sh lqf
lqf is exist
[root@centos8 data]# ./createuser.sh test
test is created
id test
uid=1001(test) gid=1001(test) groups=1001(test)
2、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@centos8 ~]# vim .vimrc
set ignorecase
set cursorline
set autoindent
autocmd BufNewFile *.sh exec ":cal SetTitle()"
func SetTitle()
if expand("%:e")=='sh'
call setline(1,"#!/bin/bash")
call setline(2,"#")
call setline(3,"#*****************************************************")
call setline(4,"#Author: lqf")
call setline(5,"#QQ: 393833084")
call setline(6,"#Date: ".strftime("%Y-%m-%d"))
call setline(7,"#FileName: ".expand("%"))
call setline(8,"#URL: http://www.magedu.com")
call setline(9,"#Description: The test script")
call setline(10,"#Copyright(c): ".strftime("%Y")." All rights reserved")
call setline(11,"#******************************************************")
call setline(12,"")
endif
endfunc
脚本格式结果如下图
